This document outlines different terrestrial and aquatic ecosystems and discusses how human activity affects the environment. It describes forest, mountain grasslands, deserts and steppes as terrestrial ecosystems and marine ecosystems such as sandy beaches, rocky shores and the open sea as well as freshwater ecosystems like rivers and lagoons as aquatic ecosystems. The document also explains how pollution, deforestation, desertification, and endangered species are effects of human activity on the environment.

16. Deforestation

17. Desertification

18. Endangered species

19. Effects of human
activity on the
environment
Pollution: The acumulation of
rubbish and harmful substances
in air, water and soil
Deforestation: Disappearance
of forest
Desertification: The slow
transformation of fertile soil
into desert
Endangered species: The living
things at risk of becoming
extinct
