HUMAN BEINGS AND ECOSYSTEMS

HUMAN ACTIVITY ALTERS ECOSYSTEM

Our activities alter ecosystems for three reasons:We overexploit natural resources.

We occupy the natural environment.

We cause pollution.

WE OVEREXPLOIT NATURAL RESOURCES

Natural resources are everything we obtain from ecosystems and consume and use to realise our activities.

Overexploiting means we extract natural resources from the environment faster than they regenerate or replace themselves.

WE OCCUPY AND DESTROY THE NATURAL ENVIRONMENT

We occupy areas that were once natural ecosystems.For example, we substitute forests for cities.

WE CAUSE POLLUTION

We produce dangerous residues that we release into the environment.

WHAT PROBLEMS DO WE CAUSE ?

These actions cause many problems.For example:

Loss of biodiversity.

Loss of natural spaces.

Climate change.

Some ways of protecting the planet

Exploit resources carefully.

Protect natural spaces.

Protect endangered species.

Reduce pollution.
