IV) INTRODUCTION

With the growing population even the environmental problems are increasing and of late they have taken a demonic size, which is commanding expert attention to be solved. There are problems like Air Pollution, Drinking waterpollution, Global warming, Hazardous Waste, Ozone Depletion and many others, which makes the list endless. As globalization paves its way across the world these problems no longer remain local problems but become international issues and there are numerous causes of these problems, some of which are created by man and can also be controlled by man. However, some people do something to control thoseproblems which are related with the environment, but nobody mind about those problems. In fact, it is really difficult to change people’s mind because all the stuff that they do are dangerous for the environment, but the main things which contaminate the ecosystem are the factories .Besides the environmental problems is makes to happen the “species extinction” . The environmental problems in theworld are increasing because the people and the factories contaminate the whole world. Nowadays, the global warming, resource depletion, pollution, and others are still causing some problems which are really dangerous, those problems have to be solving otherwise the earth is going to disappear.

V) DEVEPLOMENT OF THE TOPIC
DEFINITION
The environmental problems are some troubles which makesthe ecosystems destroyed. Those problems are classified in some groups, but as we said in the introduction some of them are really dangerous.

* The environmental problems related with land.
Those problems are evolved with the problems which theecosystem always suffers.
TYPES OF ENVIRONMENTAL PROBLEMS

Every year in the U.S. factories release over 3 million tons of toxic chemicals into the land, air and water. This hazardous waste causes us to lose over 15 million acres of land every year, it leads to respiratory complications and other health problems and it makes our rivers and lakes too polluted for us to swim in and drink. Butfactories are only part of the problem of pollution. Pollution is caused by industrial and commercial waste, agriculture practices, everyday human activities and most notably, modes of transportation. No matter where you go and what you do, there are remnants of pollution.
