AIR POLLUTION

We are nowadays becoming more aware of pollution matters that affect dramatically our lives, especially there is growing concern about air pollution. There are some reasons that lead to this kind of pollution. Firstly, the development of industrial zones, factories and building construction areas is producing a large amount of dust and poisonous air. Especially in developing countries, people don’t pay much attention to the air treatment process which makes the air pollution even worse. Secondly, because of the increasing urbanization, it can be easily seen that there is always a lot of traffic in rush hour and dust on the road these days. The smoke from vehicles and manufacturing exhaust increases the amount of carbon dioxide in the air which makes US feel really hard to breathe. The consequences are very bad. Smog and dust can do serious harm to our health, especially our lungs. We have thousands of asthma and adult respiratory distress cases each year which raise concern about the air quality. Moreover, acid rain is becoming more and more popular which damages crops and fields. Many people believe that air pollution is also causing global warming and it is difficult to improve the air without the efforts of all countries around the world.

Saving the Environment: One Home at a Time

Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.

First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.

Second, we need to watch the amount of water used in the home. It can be conserved by taking short shower instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.

Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.
