Diversity and Interdependence

Certain animals live in specific environments. These environments must be preserved by decreasing developments made by humans and maintaining the environments natural conditions. What happens if these environments are not preserved?

• The animals may become extinct

• The animals will learn to live in a new habitat that replaces their current habitat

• The animals will move to a different area

• The animal will have offspring with changed features that match their new habitat
