REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM


To the Board of Directors of Humankind Benefit
Corporation
and the Shareholder of Humankind US Stock ETF


In planning and performing our audit of the financial
statements of Humankind US Stock ETF, a series of
shares of beneficial interest in Humankind Benefit
Corporation (the "Fund"), as of December 31, 2021,
and for the period then ended, in accordance with the
standards of the Public Company Accounting
Oversight Board (United States) ("PCAOB"), we
considered the Fund's internal control over financial
reporting, including controls over safeguarding
securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion
on the financial statements and to comply with the
requirements of Form N-CEN, but not for the purpose
of expressing an opinion on the effectiveness of the
Fund's internal control over financial reporting.
Accordingly, we express no such opinion.

The management of the Fund is responsible for
establishing and maintaining effective internal control
over financial reporting.  In fulfilling this responsibility,
estimates and judgments by management are
required to assess the expected benefits and related
costs of controls.  A fund's internal control over
financial reporting is a process designed to provide
reasonable assurance regarding the reliability of
financial reporting and the preparation of financial
statements for external purposes in accordance with
accounting principles generally accepted in the United
States of America ("GAAP").  A fund's internal
control over financial reporting includes those policies
and procedures that (1) pertain to the maintenance of
records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets
of the fund; (2) provide reasonable assurance that
transactions are recorded as necessary to permit
preparation of the financial statements in accordance
with GAAP, and that receipts and expenditures of the
fund are being made only in accordance with
authorizations of management and directors of the
fund; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized
acquisition, use or disposition of a fund's assets that
could have a material effect on the financial
statements.

Because of inherent limitations, internal control over
financial reporting may not prevent or detect
misstatements.  Also, projections of any evaluation of
effectiveness to future periods are subject to the risk
that controls may become inadequate because of
changes in conditions or that the degree of
compliance with the policies or procedures may
deteriorate.

A deficiency in internal control over financial reporting
exists when the design or operation of a control does
not allow management or employees, in the normal
course of performing their assigned functions, to
prevent or detect misstatements on a timely basis.  A
material weakness is a deficiency, or combination of
deficiencies, in internal control over financial
reporting, such that there is a reasonable possibility
that a material misstatement of the Fund's annual or
interim financial statements will not be prevented or
detected on a timely basis.


Our consideration of the Fund's internal control over
financial reporting was for the limited purpose
described in the first paragraph and would not
necessarily disclose all deficiencies in internal control
that might be material weaknesses under standards
established by the PCAOB.  However, we noted no
deficiencies in the Fund's internal control over
financial reporting and its operation, including controls
over safeguarding securities, that we consider to be a
material weakness, as defined above, as of
December 31, 2021.

This report is intended solely for the information and
use of management and the shareholders of
Humankind US Stock ETF, the Board of Directors of
Humankind Benefit Corporation and the Securities
and Exchange Commission and is not intended to be
and should not be used by anyone other than these
specified parties.
