Biodiversity

Habitat Loss

Alien/Invasive species

Habitat fragmentation is the division of a large habitat area into smaller areas. Affects the amount and type of species that live in the smaller areas.

This is a problem because it is resulting in loss of biodiversity and it is damaging the ecosystem.

Air Pollution

Air pollution Consists of chemical substances and particles released into the atmosphere, mainly by human activities. The major cause is the burning of fossil fuels.

Water pollution puts chemicals in water supply. Chemicals are the cause of it

Acid rain is when air pollution causes rain to become acidic. It forms from low ph of water.

Overpopulation

One effect of this is habitat losses.

Overexploitation

Overexploitation is basic overuse of animals and land that leads to a decrease in populations. It can cause a disease to spread.

Pollution

Biomagnification is the increase in concentration of a substance as it moves up the food chain (toxins)

DDT magnification almost caused the population to go extinct

Climate Change

Decline in cold-adapted species like polar bears

Melting of glaciers and rising sea levels

Coastal flooding and shoreline erosion

Heat-related human health problems.

Droughts and water shortages

Preventing Biodiversity loss

Sustainable use is the use of natural resources in a way that meets the needs of the present and preserves the resources for the future

Umbrella species are a species that, if protected, also provides protection to other organisms by default.

It is important because if you protect one species you will protect 350 other species.
