Human Impact Assessment

Deforestation will most directly result in an immediate increase in

• carbon dioxide in the air

• oxygen in the air

• wildlife populations

• renewable resources

Some organizations are buying up sections of forest land. Once purchased, these sections of forest will never be cut down. The main reason for protecting these sections of forest is to

• cause the extinsion of undesirable animals

• prevent these trees from reproducing too fast

• maintain the biodiversity of the living environment

• provide more land for agriculture purposes

The rapid destruction of tropical rain forests may be harmful because of all the following EXCEPT

• the land will be used for animal agriculture which could lead to desertification and increase methane prodution

• the cutting down of trees will result in increased carbon dioxide in the air

• deforestation will decrease biodiversity and can lead to the collapse of other ecosystems

• the removal of trees will increase the space for wildlife

Increased production of goods makes our lives more comfortable, but causes an increase in the demand for energy and other resources. One negative impact of the situation on ecosystems is the increase of

• pollution levels in the atmosphere

• renewable resources

• the diversity of plant species

• increased habitat space for wildlife

One way that humans could have a positive impact on local environments is to

• generate waste products as a result of technological advances

• use resources that are renewable

• increase the land used for animal agriculture

• increase the use of pesticides

When human-made chemicals and garbage find their way into nature and harm the air, soil, and water it is called

• pollution

• habitat destruction

• overexploitation

• climate change
