– its doors are large amount of carbon
– a lodgement of CO2 is released into the atmosphere when P is dog up for:
– compost – land

Question 19

How does an increasing population affect the environment

Create land for buildings, quarrying, farming and dumping waste

Question 21

What problems do deforestation Course

Answer 21

It causes less carbon dioxide to be taken in

More carbon Dioxide in the atmosphere when the trees are burnt to clear land

There is less biodiversity

Question 22

What are the effects of global warming

Answer 22

Rising sea levels

Changing distribution of wild animals and plant species

Less biodiversity

Changes in migration pattern

Answer 23

Reading programs for endangered species

Protection and Regeneration of rare habitats

Rita duction of field margins and hedgerows
