highlight
         material differences, if any, in the terms and price of securities

Business
         Combination, please:

                Revise your disclosure here, and elsewhere throughout the proxy
              statement/prospectus as appropriate, to show the potential impact
of redemptions on
              the per share value of the shares owned by non-redeeming
shareholders by including
              a tabular presentation relating to redemption sensitivity showing
a range of
              redemption scenarios, including an interim redemption level in
addition to the
              minimum and maximum levels that you are already showing.
                Disclose all possible sources and extent of dilution that
shareholders who elect not to
              redeem their shares may experience in connection with the
business combination.
              Provide disclosure of the impact of each significant source of
dilution, including the
              amount of equity held by founders, convertible securities,
including warrants retained
              by redeeming shareholders, at each of the redemption levels
detailed in your
              redemption sensitivity analysis, including any needed
assumptions.

                It appears that underwriting fees remain constant and are not

Interests of ENVI Directors and Officers in the Business Combination, page 13

6.       Please expand your disclosure here and in the similarly captioned
section on page 140 as
         follows.
             Quantify the aggregate dollar amounts contributed and describe the
nature of what
              the sponsor and its affiliates have at risk that depends on
completion of a business
              combination. Include the current value of securities held, loans
extended, fees due,
              out-of-pocket expenses and any other items for which the sponsor
and its affiliates
              are awaiting reimbursement. Provide similar disclosure for the
company   s officers
              and directors, if material.
             Highlight the risk that the sponsor will benefit from the
completion of a business
              combination and may be incentivized to complete an acquisition of
a less favorable
              company or on term less favorable to shareholders rather than
liquidate. Please also
              highlight this in the bulleted risk factors beginning on page 76.
             We note disclosure here and throughout the proxy
statement/prospectus regarding
              conflicts of interest stemming from current investments by the
sponsor and its
              affiliates that are at risk and will become worthless without the
consummation of a
              business combination. Please revise your disclosure here and in
the similarly
              captioned section beginning on page 140 to highlight that the
sponsors and public
              shareholders may experience different rates of return in the
combined company
              should the business combination occur. Discuss in both
quantitative and qualitative
              terms how economic incentives could result in substantial
misalignment of
              interests. For example, since your sponsor acquired a 20% stake
for approximately
              $0.0001 per share and the merger consideration is based on a
deemed price per share
              of $10.00 a share, the insiders could make a substantial profit
after the initial business
              combination even if public investors experience substantial
losses. Please also
              highlight this information in your Questions and Answers and in
the bulleted risk
              factors beginning on page 76.
Risk Factors
After the completion of the Business Combination, we may be required to record
write-downs or
write-offs..., page 78

7.       Please revise your disclosure here to explain that the process for
acquiring GreenLight
         differs from a traditional IPO. Disclose the material risks to
unaffiliated investors
         presented by taking GreenLight public through a merger rather than an
underwritten
         offering. These risks could include the absence of due diligence
conducted by an
         underwriter that would be subject to liability for any material
misstatements or omissions
         in a registration statement.

The ability of our public stockholders to exercise redemption rights with
respect to a large
number of our shares..., page 79

8.       We note the following risk disclosure on page 79: "Raising additional
third-party
         financing may involve dilutive equity issuances or the incurrence of
indebtedness at
         higher than desirable levels. Furthermore, this dilution would
increase to the extent that
         the anti-dilution provision of the ENVI Class B Common Stock result in
the issuance of
         ENVI Class A Common Stock on a greater than one-to-one basis upon
conversion of the
         ENVI Class B Common Stock at the time of the Business Combination."
             The disclosure in the latter quoted sentence appears to conflict
with disclosures
              elsewhere in the proxy statement/prospectus, such as on pages 4
and 117, where you
              state that pursuant to the Sponsor Letter Agreement, the parties
to that agreement,
              including the Initial Stockholders, agreed to waive their
anti-dilution rights or similar
              protection with respect to their shares of ENVI Class B Common
Stock whether
              resulting from the transactions contemplated by the Business
Combination
              Agreement or otherwise. Please revise your disclosures throughout
to reconcile this
              inconsistency or advise.
             If your sponsor will receive additional securities pursuant to an
anti-dilution
              adjustment based on the company   s additional financing
activities, please quantify
              the number and value of securities the sponsor will receive. In
addition, disclose the
              ownership percentages in the company before and after the
additional financing to
              highlight dilution to public stockholders.

9.       We note your disclosure here that in August 2021, ENVI entered into a
loan agreement
         with HB Strategies in the amount of $500,000 for working capital
purposes.
             Please expand your disclosure here and elsewhere throughout the
proxy
             statement/prospectus, as appropriate, to include the material
terms of the promissory
             note, including whether the promissory note is interest bearing,
what amount, if any,
             remains outstanding, and when and how such note is payable. In
that regard, we note
             disclosures elsewhere in the proxy statement/prospectus indicating
that the working
             capital loan from HB strategies may be convertible into private
placement-equivalent
             warrants in connection with the business combination, at the
option of the lender.
             Additionally, please file the promissory note between ENVI and HB
strategies as an
             exhibit or tell us why you believe such filing is not required.

Background to the Business Combination, page 117

12.      With reference to the third full paragraph on page 118, which states
that ENVI approached
         or was approached by over 250 potential business combination targets
and had discussions
         with 96 firms since January 19, 2021, please:
             Explain how you narrowed the potential business combination
targets from over 250
             to 96.
             Revise to clarify whether these 96 companies include the 30
companies ENVI
             approached or was approached by between March 31, 2021 through
mid-April 2021
             referenced on page 119, or whether the group of 96 companies
constituted an initial
             set of business combination targets.
             Describe the analysis and evaluation that was conducted on the set
or sets of
             companies with which ENVI held discussions since January 19, 2021.
Describe in
             more detail how these companies were identified and the varying
levels of
             preliminary due diligence performed, as applicable.
             To the extent material, please identify the individuals who
participated in these
             preliminary and other meetings and discussions.

13.      We note that beginning on March 31, 2021 through mid-April 2021, ENVI
approached
         and was approached directly or indirectly by over 30 separate entities
that may have been
         potential targets for a business combination.
             With reference to your disclosure on page 119 that ENVI approached
GreenLight on
             March 31, 2021 to begin to discuss the terms of a potential
business combination "as
             GreenLight was involved in a process to consider a business
combination," please
             revise here or elsewhere, as appropriate, to discuss how and why
GreenLight became
             interested in a SPAC merger as opposed to a more traditional IPO
transaction.
             With respect to the other 29 companies you approached or were
approached by
             during this period, please disclose the information you had with
respect to the
             candidates being considered, the extent of any negotiations with
the other potential
             targets, and when and why each company was eliminated as a
potential target.
             Disclose when you engaged Latham in connection with both the
GreenLight business
             combination as well as the combination with another entity you
abandoned on March
             31, 2021.
14.      We note your disclosure on page 119 that on April 15, 2021, ENVI

         provide the framework for a potential business combination, and later
sent a revised draft
         of such letter on April 20, 2021 after receiving comments from
GreenLight.
             Please expand your disclosure to describe why ENVI's management
determined to
              send GreenLight a non-binding letter of intent on April 15, 2021.
Describe the basis
              for management's belief, if any, that GreenLight provided an
attractive, or the most
              attractive, potential business combination.
             Please revise your disclosure throughout this section to provide
greater detail as to
              how the material terms of the transaction structure and
consideration evolved during
              the negotiations through proposals and counter-proposals. The
disclosure should
              provide shareholders with an understanding of how, when, and why
the material
              terms of your proposed transaction evolved and why this
transaction is being
              recommended as opposed to any alternatives.
             Please provide additional detail regarding how ENVI arrived at the
initial valuation
              range of $1.0 to $1.2 billion for GreenLight included in the
April 15, 2021 non-
              binding LOI. We note your disclosure that ENVI generally
incorporated proposed
              modifications to the LOI from GreenLight in this regard. Address
the proposed
              modifications in your revisions and if material, discuss any
analysis, its conclusions
              and underlying assumptions, and the extent to which the ENVI
Board considered
              them. Please also expand the discussion of the factors or
conditions that supported
              and led to the selection of the high-end valuation at $1.2

             Disclose the extent to which the early development stage of ENVI's

             health product candidates was considered in the decision to pursue
GreenLight as an
             acquisition candidate. Please disclose the type(s) and number of
product
             candidates the other acquisition candidates had in their
respective pipelines and the
             development stages of such candidates.
             With reference to the first paragraph on page 126, please expand
this disclosure to
             discuss how the board considered the various conflicts of
interests of your sponsor
             and your officers and directors, such as those discussed beginning

             210, in negotiating and recommending the business combination.

              information and provide the basis for the exclusion.
Certain Company Projected Financial Information, page 136

17.      We note your disclosure that GreenLight provided the ENVI board with
internally-derived
         forecasts for each of the years in the five-year period ending in
December 2025, including
         material projected financial information summarized in the table at
the top of page 139.
         We have the following comments regarding this disclosure:
             Describe the process undertaken to formulate the forecasts and
assumptions and the
             parties who participated in the preparation of the forecasts.
             We note the "operational assumptions" referred to in your
disclosure beneath the
             projections table are not presented with specificity and should be
revised. Please
             quantify the bases and assumptions underlying the projections,
including earnings
             growth rates, operating costs, projected market penetration rates,
discount rates, etc.
             The level of detail provided must be sufficient enough for an
investor to understand
             the reasonableness of the assumptions underlying the projections
as well as the
             inherent limitations on the reliability of projections in order to
make informed
             investment decisions.
             Particularly in light of the fact that the various GreenLight
programs mentioned in the
             assumptions have not been approved by any regulator, ensure you
fully explain how
             you arrived at your revenue projections. For instance, in the
third to last bullet on
             page 139, we note that you assume that GreenLight will "complete
development of
             all programs in the pipeline and obtain all required regulatory
approvals on time." If
             you assessed the probability of regulatory/technical success,
ensure you provide such
             details.
             Explain how management and the Board considered and relied upon
the forecasts,
             particularly in light of the length of the projections and
GreenLight's current status as
             a development stage company with no approved products.
             Explain to us the extent you have considered providing separate
forecasted financial
             information for each group of product candidates based on their
stage of
             development.
             Additionally, discuss the possible impact if the assumptions are
incorrect.
Fees and Expenses, page 136

18.      Please revise the first paragraph of this section to disclose the
amount of fees Duff
         & Phelps received upon delivery of the fairness opinion to the ENVI
Board and the
         amount it will receive upon completion of the business combination. To
the extent any
         amount otherwise earned is contingent upon completion of the
transaction, so state.

         candidate: "We are implementing good manufacturing practice (GMP)
         systems   practices that ensure pure, safe, and effective products
to support clinical
         production using our process." We also note that with respect to your
influenza vaccine
         candidate, you state on page 237: "This combination of antigens is
expected to provide a
         robust and potentially broad protective immune response to influenza
viruses." As safety
         and efficacy determinations are solely within the authority of the FDA
and comparable
         regulatory bodies, it is inappropriate to state or imply that your
product candidates are safe
         or effective. Please revise these and other similar statements
throughout your prospectus
         that suggest the safety and efficacy of your human health candidates.
Where you deem
         appropriate, you may present objective data without including your
expectations or
         conclusions related to safety or efficacy.
Our pipeline includes 5 human health products and 7 agricultural products, page
234

21.      We note the inclusion of your pipeline table at the top of page
         224. The pipeline table should graphically demonstrate the current
status of your product
         candidates as well as indicate the material stages you will need to
complete before
         marketing your products. The table should be a reflection of the
narrative disclosure in the
         prospectus and should not be used to prematurely project successful
completion of the
         stages required prior to regulatory approval and commercialization. A
narrative discussion
         is more appropriate for the next steps or aspirational plans for your
product candidates,
         such as intended regulatory submissions or potential partnerships. As
such, we have the
         following comments on your pipeline table:
             Disclosure on page 224 indicates that GreenLight is using its
platform to "develop
              and commercialize products that address agricultural, human
health, and animal
              health issues." Given that your human health and agricultural
products will be subject
              to different regulatory review processes, please revise to
present human health
              products and agricultural products (which may include both plant
and animal health
              products) in separate pipeline tables.
             Specifically with respect to your human health product candidate
pipeline table,
              please revise the format as follows: (1) Include separate columns
for each of
              preclinical, Phase 1, Phase 2 and Phase 3 phases of testing. With
respect to columns
              representing preclinical stages of development, note that we will
not object to up to
              two columns labeled as "discovery" and/or "IND-enabling." Ensure
the shaded
              progress arrows in your pipeline table accurately indicate the
current development
              status of each product candidate to date. (2) Also include a
column identifying your

              next anticipated milestone for each program. In this column, only
provide the next
              material step in the regulatory review process rather than
listing all future steps or
              phases. Additionally, throughout the proxy/registration
statement, please revise to
              define shorthand designations, acronyms, scientific/technical and
other material terms
              at first use. For example only, we note that you used the acronym
"SCD" in the
              phrase "SCD gene therapy" in the pipeline table without
definition.
                With respect to your agricultural products pipeline, we note
disclosure on page
              56 that indicates GreenLight currently has one "animal health"
product which is
              intended to control the Varroa mite, which you appear to have
included in your
              pipeline table as an "agricultural product." Please tell us your
consideration of
              identifying the Varroa mite as an "animal health" product in an
agricultural products
              pipeline table.

22.      With reference to the inclusion of "supra-seasonal flu" and "antibody
therapy" as human
         health products in your pipeline table, we refer you to the bulleted
list of "planned
         products and milestones" on page 228 where you indicate that you are
planning to conduct
         Phase 1 trials for supra-seasonal flu and antibody therapy in 2024 and
for sickle cell
         disease gene therapy in 2025. Given the lack of any other substantive
disclosure
         elsewhere in the proxy statement/prospectus regarding the former two
programs and the
         status of any platform development specific to these indications or
uses, it is seemingly
         premature to highlight these programs in your pipeline table.
Similarly, with respect to
         the sickle cell gene therapy program, we note that there is limited
disclosure regarding the
         concept for your sickle cell disease gene therapy candidate on page
238. Similarly, with
         reference to the inclusion of your agricultural candidates intended to
target "fusarium,"
         "diamondback moth," and the "two-spotted spider mite," we note that
proxy
         statement/prospectus lacks any substantive disclosure regarding the
development status of
         these programs. Please revise to remove these programs from the
pipeline table or advise.

Human Health Product Pipeline
Achievements to date and future milestones, page 236

23.      We note your descriptions of the achievements to date and anticipated
milestones for your
         human health candidates beginning on page 235.
             Please revise your discussion of the preclinical studies of your
vaccine candidates and
            human health products conducted to date to provide additional
material details.
            Please expand your discussion of your preclinical animal studies to
briefly describe
            the type and nature of the studies and how they were or will be
conducted, the
            number of animal models used, the number of tests conducted, and
the number of
            participants. Specify the primary and secondary endpoints of the
different studies, the
            results as they relate to the endpoints and any statistical
analysis that was done or will
            be done, including statistical significance, if applicable.

labels.

Our seasonal influenza vaccine candidate
Achievements to date and future milestones, page 237

24.      With respect to your influenza vaccine candidate, you state on page
237: "Further
         preclinical validation in a ferret model is ongoing, and clinical
trials are expected to start
         in the second half of 2022." With respect to this human health product
candidate and
         others, please revise your disclosure as appropriate to provide the
basis for your
         statements regarding expectations of when clinical trials for such
products will
         commence. Describe any testing or additional steps required prior to
submitting an IND
         application to the FDA, and indicate when you plan to submit such
application as you
         stated on page 237 for your COVID vaccine candidate.

Plant Health Product Pipeline, page 239

25.      With respect to each of your plant health product candidates that have
not already been
         submitted to the EPA for approval, please revise your disclosure
regarding field testing to
         indicate the geographies where such ongoing or anticipated testing is
being or will be
         conducted and describe any testing or additional steps required in
order to obtain EPA
         registration approval. Indicate when any field testing will be
completed and outline the
         the timeline for submission to the EPA. Additionally, with respect to
any field tests that
         have demonstrated adverse effects, such as you disclose with respect
to your verroa mite
         candidate on page 241, please discuss any material impact such adverse
effects may have
         on the development or approval of the product candidate.
Strategic Collaborations, page 239

26.      We note your disclosure that you intend to seek established
collaborators to co-develop or
         commercialize your human health product candidates so as to "share the
risk and reward
         of [your] portfolio while acquiring the capabilities required to
launch commercial
         products" and that you also reserve certain early-stage programs to
commercialize without
         partners. Please revise to disclose which of the 5 human health
programs referenced in
         the prospectus you reserve for potential commercialization without
partners. In this
         regard, we note that the current pipeline table does not reflect a
yellow dot for
         "partnership milestone" for supra-seasonal flu, antibody therapy, and
SCD gene therapy.
Market Opportunity, page 240

         Here and elsewhere in the proxy statement/prospectus where you discuss
addressable
         markets, please expand your addressable markets estimates and provide
the sources upon
         which you are basing your calculations as well as any material
assumptions and
         limitations associated with your estimates.
Crop physiology, page 243

28.      We note the following statement on page 243: "Until now, insecticides
and fungicides
         have offered us a more rapid and reliable pathway to commercial
products." Given that
         none of your agricultural products has been granted EPA approval and
none has been
         commercialized to date, please remove this statement.
Environmental, Social, and Governance (ESG) Strategy, page 244

29.      We note your discussion of GreenLight's ESG strategy beginning on page
244. We have
         the following initial comments:
             Please revise to define the use of the following terms in this
section and elsewhere in
              the proxy statement/prospectus: "sustainable," "sustainable
solutions," "green,"
              and "clean."
             Please revise to provide support for this claim: "GreenLight   s
RNA is produced from
              natural materials using a clean enzymatic process with very
little waste or harmful
              emissions and after application our RNA product candidates
disappears in a few
              days." Quantify the phrase "very little waste or harmful
emissions."
Patents, page 247

30.      In relation to the company's material patents, please further revise
your disclosure to
         clearly describe on a patent family basis the type of patent
protection granted for each
         product or technology (composition of matter, use, or process), the
range of expiration
         years of each patent, and the jurisdiction, including any foreign
jurisdiction, of each
         material pending or issued patent. Be sure to segregate issued patents
and patent
         applications. In this regard, it may be useful to provide this
disclosure in tabular form.
Intellectual Property Agreements, page 248

31.      With respect to any material license agreement, please revise your
disclosure to describe
         the material terms of such agreements, including:

Research and Development Expenses, page 264

32.      We note the significant increase in your research and development
expenses and it appears
         that you have multiple products in varying stages of development. We
also see from your
         disclosure on page 262 that your direct research and development costs
are tracked on a
         program-by-program basis for your product candidates. Please revise
future filings to
         provide more detail for your research and development expenses for
each period
         presented, including but not limited to by product candidate. To the
extent that you do not
         track expenses by product candidate, please disclose as such. Please
separate research and
         development expenses between your human health program and your plant
health
         program.
Comparison of Stockholders' Rights
Choice of Forum, page 326

33.      We note your disclosure on page 326 regarding the Choice of Forum
provisions in the
         Proposed Charter. In part, you indicate that the Proposed Charter
designates the federal
         district courts of the United States as the exclusive form for the
resolution of any
         complaint asserting a cause of action arising under the Securities Act
of 1933, as
         amended. Please revise this section, and other sections indicated
below, as follows:
             Please revise this section to clearly and specifically state
whether claims arising
              under the Exchange Act may be brought in any U.S. federal court.
             Please revise your risk factor disclosure on page 72 to state that
there is uncertainty as
              to whether a court would enforce your choice of forum provision
applicable to
              Securities Act claims. In that regard, we note that Section 22 of
the Securities Act
              creates concurrent jurisdiction for federal and state courts over
all suits brought to
              enforce any duty or liability created by the Securities Act or
the rules and regulations
              thereunder.
             We note that a section captioned "Forum Selection" on page 338
appears to contain a
              conflicting statement regarding the exclusive forum for
resolution of claims under the
              Securities Act. There, your disclosure states: "The Proposed
Charter designates the
              United States District Court for the District of Delaware as the
exclusive forum for
              the resolution of any complaint asserting a cause of action
arising under the Securities
              Act of 1933, as amended." Please revise your disclosure here, or
