I. Introduction.
A variety of environmental problems now affect our entire world.  As globalization continues and the earth's natural processes transform local problems into international issues, few societies are being left untouched by major environmental problems.
Some of the largest problems now affecting the world are: Acid Rain,  Air Pollution, GlobalWarming, Hazardous Waste,  Ozone Depletion, and Water Pollution.
II. Justification.
We chose this topic because we wanted to know more about the environmental problems that now affect our planet and inform our classmates abou these problems, their causes and effects, the posible solutions and some actions that we can take to reduce this problem.
III. Objectives.
* General.

In this work we want toinform people about the pollutants, their origin and possible solutions, to promote awareness of this problem and if possible, to develop actions that contribute the control of polluting our environment.

* Specific

* To learn about different environmental problems that now affect Earth.
* To explain and analyze in a simple and easy way to understand environmental problems on theplanet.
* To explain the consequences of some environmental problems.
IV. Development of the topic.
A. Definition.
An environmental problem is a known process that has negative effects on the sustainability of the environmental quality necessary for the well being of the organisms living in it.
B. History
The human beings, appeared late in Earth history, but has been able to modify theenvironment with their activities. Although certainly the first humans lived more or less in harmony with the environment, like other animals, their absence from the wild began in prehistoric times, with the first agricultural revolution. The ability to control and use fire allowed to modify or remove the natural vegetation.
As human populations remained small with modest technology, its impact onthe environment was only local. However, as the population grew and their technology improved and increased, appeared more significant and widespread problems. The rapid technological advance occurred after the Middle Ages led to the Industrial Revolution, which resulted in the discovery, use and exploitation of fossil fuels and the intensive exploitation of mineral resources of the Earth.
It waswith the Industrial Revolution when humans began to really change the face of the planet, the nature of its atmosphere and the quality of the water. Today, unprecedented demand for the rapid human population growth and technological development subject to the environment is producing an ever-accelerating decline in its quality and its ability to support life.

C. Classification of EnvironmentalProblems.
1. Water pollution
The problem of ocean pollution affects every nation around the world.  This is especially true because water is able to transport pollution from one location to another.
For many years, chemicals were dumped into bodies of water without concern.  While many countries have now banned such behavior, it continues to go on today.
As the world has industrialized...
