Question

What are sustainable use practices?
any materials that exist in nature and that are used by humans
the managed consumption of natural resources to prevent their depletion or environmental destruction
the deployment of fossil fuels to environments that previously did not have access to such resources
ways in which individuals are able to conserve native animal and plant species

Answer 1

Best choice:
- "the managed consumption of natural resources to prevent their depletion or environmental destruction."

Why: sustainable use practices are methods of using natural resources so they renew or persist, while meeting human needs now and in the future. They involve limits, monitoring, and management to avoid depletion or ecosystem damage.

Notes on the other options:
- "Any materials that exist in nature and that are used by humans" describes natural resources, not sustainable use.
- "The deployment of fossil fuels to environments that previously did not have access to such resources" is not sustainable use and typically increases environmental harm.
- "Ways in which individuals are able to conserve native animal and plant species" describes conservation actions, which are related and complementary to sustainable use but are not a complete definition of it.

Examples of sustainable use practices: selective logging, fishing quotas and seasonal closures, rotational grazing, community-based forest management, agroforestry, water-saving irrigation, harvesting non-timber forest products at sustainable rates, and ecotourism with strict impact limits.
