OUR PLANET -->

In this planet there are many environmental problems, like the greenhouse effect, the global warming, climate change, the destruction of forests and of the Ozone Layer, etc...

And all the problems are serious, because one on one, the planet is going to be destoy.

And this is my opinion:

I think,

we have to think more times in the earth and leave to think in us,

because we buy and us more thinks that we need, and all is plubicities' fault,

because they generate a necessity, we don't need, and is useless.

I'm going to talk about the global warming:

Although greenhouse gases are created by many different human activities,

there are two principal causes of the increase in the amount of CO2 in the earth's atmosphere, burning fossil fuels and deforestation.

It is important to remember the underlying cause of all increases in human activity is the rapidly increasing world population.

and there are some alternatives energies, like hydroelectricity or tidal power:

Hydroelectricity:

the water stored in reserviors created by dams has potential energy.

when it is released though the dam, it produces kinetic energy that can be used to turn turbines.

steep river valleys provide the best natural conditions for hydroelectric dams and reservois are significant sources of fresh water.

Tidal power:

tidal energy is harnessed by constructing a dam or "garrage" across a tidal basin, behind whitch tidal water can be trapped, and then released to create kinetic energy to turn tubines.
