My View on Environmental Pollution

It is well known that the world we live in is getting worse and worse because of the increasing environmental destruction. For example, many people are cutting down trees for fuel or sale, but deforestation results in the increase of global temperature and unpleasant change of climate. Besides, human beings are being bothered by water pollution, air pollution and noise pollution.
Governments of most countries have taken some measures to stop the environment from being further damaged. Many people are trying hard to find ways to prevent the pollution from going on. Laws concerning environmental protection have been put into effect and siwater pollution
tuations in many regions have improved. 
However, the problem of environmental protection is far from being solved completely. On the one hand, environmental pollution and destruction are getting worse and worse with the rapid development of science and technology. On the other hand, many people have realized the urgency of solving the problem. In brief, we have a long way to go before we can make the earth a better place to live in.

The Greenhouse Effect

    The “Greenhouse Effect” refers to the warming of the earth due to the increasing amount of carbon dioxide in the atmosphere. Carbon dioxide is a gas produced every time a fuel such as coal, oil or natural gas is burned. This carbon dioxide increases the heat of the atmosphere, and thus warms the planet.
    According to scientists, the “Greenhouse Effect” is the most serious problem our planet has ever faced. First of all, the level of the ocean could rise, because ocean water expands as it grows warmer. Melting polar icecaps could also contribute to an increase in the level of the ocean. People living on coastlines might lose their homes, and cities like New Orleans might be completely submerged.
    Parts of the world that are already hot might become unbearably hotter. Hot weather means a huge increase in the use of air conditioning, which uses energy, costs money and creates pollution. It can make some people, especially elderly people and infants very ill.
    Some parts of the world might become much drier. Already many parts of Africa have suffered frequently from severe droughts. Other parts of the world might become wetter. Too much rain in some regions could kill crops traditionally grown there, and lead to hunger.
    Many scientists suggest that people need to learn to conserve fuel, since burning fuel is one of the main causes of the “Greenhouse Effect”. Government should protect forests,
since trees can help reduce the “Greenhouse Effect”. Chemicals, which increase the effect can be banned or strictly controlled. Nations should work together to prevent a global disaster, while at the same time ordinary citizens must do their part.
