1 Work elaborated by: Rui Pedro 11ºA Nº14 Escola Secundária de Arganil Ano Lectivo: 2007/2008 Global Threats and Individual Contributes to Protect the Earth

2  Men are polluting nature in many ways and that can be dangerous. Life on earth can become extinct. If we don’t start protecting our environment now, one day it will be too late.

3  We should switch lights off when they aren’t being used so that they don’t use up unnecessary energy. Using unnecessary energy doesn’t help the environment either!  We should stop using aerosols, sprays that contain CFC's which are very harmful for the ozone layer. The CFC's contribute to enlarge the hole in the ozone layer. Individual Contributions to Protect the Earth

4  We should avoid using plastics because they aren’t biodegradable, biodegradable things are destroyed by nature, but most plastics aren’t.  We shouldn’t smoke because that affects our environment and helps contributing to the destruction of the ozone layer.

5  We shouldn’t use chemical products, these are harmful to our environment as well as our health.  We should use public transports as much as possible because the more cars are used the more gases are being released into the atmosphere and these make the ozone layer problem worse.

6  We should save water (control taps, stop water running when brushing teeth or washing or even while using shampoo or shower gel), we will avoid water scarcity.  We must help to keep nature clean so that we may have a better world to live in. When we are preserving nature, we are preserving our lives.
