Question

the united nations conference on environment and development
the biodiversity treaty
the biodiversity treaty was an international agreement signed in 1992. what is the overall purpose of the biodiversity treaty?
to ensure that biodiversity remains the subject of political conflict until it is all goneto promote the conservation, sustainable use, and sharing of biodiversity worldwideto ensure that the richest nations on earth get the greatest benefits from biodiversity forever

Explanation:

The text mentions that the CBD (Biodiversity Treaty) outlined a three - pronged approach: conservation (protecting habitats, species, ecosystems), sustainable use (using nature's resources responsibly), and fair and equitable sharing of benefits. This aligns with promoting conservation, sustainable use, and sharing of biodiversity. The first option about biodiversity being a subject of political conflict until gone is negative and not in line with the treaty's goals. The third option about only the richest nations benefiting is also against the "fair and equitable sharing" principle.

Answer:

to promote the conservation, sustainable use, and sharing of biodiversity worldwide
