Guilty Parties

Pollution

Like example fertilizer is washed away into bodies of water like Gulf and Mexico which causes rapid growth of undesirable types of algae.

Pollution is when harmful substances we release into the air, land and water. They include poisonous gases or particles.

Like Plants tree humans animals and sometimes In extreme cases an entire ecosystem could be lost

Kills natural resources and Living Things

Habitat Loss

Like example the conversion of tropical forests to palm oil plantations is placing stress on population of orangutans, tigers,elephants and rhinos

When humans and their activities destroy and fragment natural habitats.

Human activities destroy fragment natural habitats

Overharvesting

Like example monogany is a threatened species of tree found in the forests of central and south America

Like example a brown tree snake and it was mistakenly shipped to Guam to ships and the population grew very fast

Causes loss of habitat from overharvesting the trees or the loss of a species of fish as a commercial source of food

This happens when human's overuse natural resources

Causes loss of biodiversity and environmental consequences

Climate Change

Like example in the artic the sea ice is melting because of the rising temputares

Climate change is when long term change  is in the patterns of earths weather

Human activities  like burning fossils release large amount of carbon dioxide and other gases in the air

Many species cannot adapt to higher temperate and changing climate patterns

Invasive species

It is causes when humans bring plants or animals from one ecosystem to another

May change the way the ecosystem functions. If no natural predator a population of invasive species often grows quickly

Introduced Species sometimes compete with native species for resources
