If we would see the color of our future, we must look for it in our present; if we would gaze on the star of our destiny, we must look for it in our hearts.

Our growing need for food, goods and energy has had many harmful effects on the environment. Gases produced by cars, power stations and factories cause acid rain, which kills trees and fish and damages buildings. By using more environmentally-friendly forms of transport, we help reduce this form of pollution.

A layer of carbon dioxide and other gases traps heat and keeps the earth at the right temperature. This is called the greenhouse effect. By burning fossil fuels (oil,coal,prtrol,etc) we are producing too much carbon dioxide, which is causing temperature to rise gradually. This global warming could lead to dramatic changes in climate.

A layer of gas called ozone protects the earth from harmful ultraviolet radiation. Certain chemicals used in industry, such as CFC's have caused a hole to develop in the ozone layer. The increased level of ultraviolet radiation damage plants and sea life, and increase the risk of skin cancer.

Most of the energy we use to heat and light buildings, run machines is made by burning fossil fuels. This will eventually run out, so we need to use more alternative sources of energy, such as wind and solar power, that are renewable and do not pollute air. We should also avoid wasting energy by using less electricity and water and insulating our houses.

We are destroying our forests, which produce oxygen and provide habitants for animals and birds. Deforestation also allows rain to wash away all the soil, making the land useless for growing things.

We pollute water by dumping waste from factories and houses, and by accidentally spilling chemicals and oil. Chemical fertilizers damage rivers and lakes by causing a layer of tiny plants, called algae, to cover the surface of the water. Organic farming does not harm the water supply.

Burying rubbish in landfills can let harmful chemicals leak through the groung into the rivers, and it uses a lot of land. Buening rubbish adds to global warming. By sorting our rubbish for recycling, we can cut down on waste.
