Create a short, general list of ways that humans impact the environment.

The affect of human activity

Humans and other organisms change the environment when they obtain food, eliminate wastes, and prepare places to live.

Sustainable Development?

What does sustainable development look like? (DRAWINGS SHOULD BE SCHOOL APPROPRIATE)

Sustainable Development

In economic terms, ecosystems are providers of goods and services (natural resources).

• Healthy ecosystems produce or replace renewable resources.

• Humans must be careful about the use of nonrenewable resources, such as fossil fuels, which cannot be replaced.

• Sustainable development provides for human needs while preserving the ecosystems that provide renewable resources.
