Human Impact

Introduction to Human Impact

Human impact on the environment carries many negative longterm consequences.

Consumption, altering habitats, and carbon emissions are all human activities destroying the natural world.

Habitat Alteration

Habitat alteration is changing earth's natural compositing by destroying habitats to build upon or fragmenting habitats for roads and access. This is the biggest threat to biodiversity.

Pollution

Pollution is the contamination of Earth's atmosphere and surface (land and bodies of water).

Disposal of human waste results in land pollution, while burning fossil fuels results in air pollution. Land and air pollution affect water contamination.

Deforestation

Deforestation is the removal and destruction of forests.

Clear cutting completely removes all trees in an area for human consumption, such as building materials, paper products, etc.

Human Population Growth

The human population has continued to increase, which means human impact on the environment will increase as well.

Concerns include lack of space, food, and other resources, as well as disease outbreaks.

Acid Rain

Acid rain is caused by burning fossil fuels, which releases acidic gases into the atmosphere. The gases latch on to water molecules and the result is acid (low pH) rain.

Acid rain results in organism death and destruction of infrastructure.
