ESSAY
Nowadays, we have many conveniences in our society which have been brought about through technology and science. However, these same advancements in technology and science have caused some very dangerous problems. These problems will not go away easily because people do not want to give up the conveniences of a modern lifestyle. The most critical problems which should be dealt with immediately are those of pollution.
Pollution caused by chemicals is a very serious problem because it causes the loss of the ozone layer. Without our ozone, not only we ourselves but all plant and animal life are exposed to dangerous rays from the sun. Aerosol cans emit chemicals which break down our ozone layer. Refrigeration and air-conditioning systems and cars also have dangerous emissions.
Perhaps the most serious threat to the planet is the warming of the earth’s atmosphere, primarily through carbon dioxide emissions. Many scientists think that the warming could be sufficient to melt the polar ice caps, thus raising the sea levels. This would mean that many parts of the world would be submerged below sea level.
There are other problems caused by pollution. Factories which make our modern conveniences emit poisonous gases into the air we breathe. The chemicals we use for cleaning and wastes from factories go into our water systems and pollute the water we drink and the fish we eat. They also kill much of the wildlife we depend on for food. Some of the pesticides we have sprayed on our crops have been found to be dangerous. This kind of pollution may stay in the ground for a very long period of time.
In conclusion, the problems created by pollution are growing daily. Because people do not want to change their lifestyles, we must invent a way to neutralize the pollutants we are putting into our environment. People need to be educated so they will stop damaging the planet. Furthermore, governments must take action to prevent individuals and companies from harming their environment.
