Introduction
Nowadays we live with several environmental problems and we must start to worry about it.
If we think in our planet 50 years ago, we see that none of those problems were talked. But now, with the globalization and the continuous natural process of the earth, it becomes imperative to think about solutions for this problems and mostly important, start to act, instead of thinking and give advices.
In this document, i’ll make a research to explain what the environmental problems are, give some examples, and talk about causes, consequences and possible solutions.

Environmental Problems
I’ve made a selection about the environmental problems I believe it’s necessary to talk about: * Global Warming * Species Extinction * Water Crisis * Deforestation * Nuclear Fallout
Next, I’ll talk about each environmental problems, describing them, explaining causes and consequences and give some possible solutions.

Global Warming

What is Global Warming?
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
Earth's climate is mostly influenced by the first 6 miles or so of the atmosphere which contains most of the matter making up the atmosphere.

Causes
The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans.
One of the first things scientists learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and
