Clue 9 


Urban sprawl

As the human population increases, we need more places to live. When villages, towns and cities get bigger we need more land to build on which threatens the wildlife that lives there.

Although small areas of wildlife habitat remain, they may be too small to support all the animals that lived there before or may be widely separated from one another. Urban sprawl also increases pollution levels, the amount of energy we use and waste we produce.


Governments can stop this happening by having stricter laws which stop builders destroying natural habitats and encourage new housing to be more environmentally friendly.
