Izaki bizidun guztiak ESPEZIEetan biltzen dira.

Espezie horretako kideek POPULAZIO bat osatzen dute.

Populazio guztien multzoak, KOMUNITATEA osatzen du.

Beste izaki bizidunbatzuetatik lortu behar

Izaki bizidunen hondarrakerabat deskonposatzen

dituzte. Hondar horietako gazt mineralak

lurrera itzultzen dira, lurra emankormantenduz.

Pollution

What is it?

It´s the release of harmful substances into the environment.

Air pollution

Water pollutionLand pollution

noise pollution

light pollution

Page 14: Ingurumena babesten- Protecting the environment

Global warming

Carbon dioxide mantains heat on

Earth and life is possible. The

atmosphere lets light in but does

not let heat out.

This effect is called Greenhouse

effect.

Too much Carbon dioxide

in the atmosphere

stops this heat from escaping.

This causes world temperatures to increase

Deforestation

It is the loss of forests.

What is it?

People cut down trees for wood and to make space for farmland.

Why?

Consequently

When trees disappear many living things around them disappear.

Beingresponsible

citizens

Save water- Have showers

instead of baths.

-Turn off taps.

Save electricity-Turn off lights

- Turn off appliances when

not using.

Save fuel-Use public transport

- Turn down heater´s

temperature.

Use waste recycling bins

Respect fauna and flora
