People take drugs in many types of reasons. Some say that they are curious or bored and just wanted to see how drugs will affect their feelings. But everyone reacts differently to drugs, and there is no no way to predict what your reaction will be. Some drugs can kill people in one use. Other think that drugs can make them feel 'good'. They think that if they are unhappy, drugs can make them feel better. And some say that drugs can dealt with their stress in lives. But drugs don't fix the problems that are causing the stress in the first place, and they don't stop the feeling themselves. Many people also take drugs because they mispercept the phrase 'everyone is doing it'. It can be hard to relate to these facts if some of your friends are using drugs, but what you do need to realise , though, is that drugs could eventually become more important to your friends than your friendship. This is true when users become addicted because they grow so dependent on and interested in getting high that they no longer have time for friends.

I think that Global Warming had caused a lot of threats to our atmosphere. Global Warming is the warming up of Earth and is caused by human activities. It is caused by the emission of greenhouse gases like carbon dioxide, methane and nitrous oxide into the atmosphere which traps heat from the sun on the Earth's surface, preventing it from escaping. Power plants emits a large amount of carbon dioxide which is produced by the burning off fossil fuels to generate electricity. Carbon dioxide emitted to the atmosphere also comes from the burning of car engines of vehicles. Buildings is said that it represent a larger source of global warming as the structure requires a lot of fuels being burnt.

Methane is obtained from the rice paddles, bovine flatulence , bacteria in bogs and fossil fuels manufacturing. Methane is produced when the fields are flooded, resulting in anaerobic situation build up and organic matter in the soils decays. Another cause of global warming is deforestation which is caused by the cutting down of trees for the development of settlements.

The effects of global warming is the rising of the avenge temperature of the earth's surface. A rise in temperature can in turn root to other alternations in the ecology, including an increase in sea levels and modifying the quantity and pattern of rainfall. An effect of global warming, various new diseases are emerging lately. These disease are occurring lately due to the increase in earth's temperature since bacteria can survive better in elevated temperatures and multiples faster in conditions that are favourable. The global warming is expected to cause irreversible changes in the ecosystem and the behaviour of animals.

All of us can do a part to save the environment. We can monitor the air, sea and land pollution, use cleaner fuels, such as natural gases or hydrogen fuel cells, which produce less or no pollutants, use CFC-products and environment friendly products and use public transport more often instead of your personal car. We can also practise the 3'R's, try not to smoke, save energy to reduce air pollutants given out by power plants and many more.
