1. English Project Work: Teresa Borges Nº21 11ºC Escola Secundária de Arganil Global threats versus Personal Strategies to Protect the Environment

2. Introduction Humans think that the Earths resources are something that we will always have. However reality is a bit different. Our planet has never been so dangerously threatened. Nowadays we are constantly reminded that the ozone hole is growing and global warming reaches levels never seen before. This work warns the most heedless to the reality in which we live: we have to take measures to support the continuity of our planet, for the sake of our continuity.

3. Some global threats: Pollution; Global Warming; Deforestation; Depletion of the ozone Layer.

4. Pollution Pollution is the introduction of pollutants, chemical substances or energy (noise, heat, or light), into the environment, arriving at a point which endangers all living creatures or the environment. It can be: Water pollution; Soil pollution; Air pollution; Sound pollution; Light pollution.

5. Global Warming When we talk about global warming we are talking about the increase in the average temperature of the Earths near surface and oceans. There are a lot of possible causes for global warming like the presence of the greenhouse gases, the variation of solar radiation, the destruction of ozone Layer and air pollution.

6. Deforestation Destruction of forests by humans. The most common causes are building of houses, preparing agriculture fields, furniture and fires.
