Air Contamination

Air Contamination

One of the most serious problems that we have in the world is the air contamination because the air is essential for our life.
I think that we can do a lot of things to improve the air we breathe all.
In Ecuador, one of the most important problem that causes a high degree of air pollution are the bad conditions of the cars that a lot of people have and didn’t care about this problem.
Many people drive in the city in cars that pollute a lot: the people do not realize this.

I think that the government must have to do something because our planet is coming down.

The air we breathe is composed of 78% nitrogen, 21% oxygen, 0.093% argon and a portion of steam or air, when we talk about air pollution, we refer to the alteration of this composition, produced by natural causes caused by man, the first can not be avoided, but the second is our obligation to avoid them. The more we contaminate; the less pure air we are going to have to breathe.

River Contamination

River Contamination

Contamination is a terrible problem around the world, water pollution too.
Water pollution all around the world is a topic known by everybody, but nobody is doing anything serious to stop it. A few foundations like NATURA is trying to prevent more contamination in our country, but people don’t make a real effort to give a hand to this projects; it’s very disappointing if that there are just a few of this kind of foundations. Pitifully the earth will not endure for ever.
What is water pollution?
Incorporation of foreign matter into the water, such as microorganisms, chemicals, industrial waste and other types, or sewage. These substances impair water quality and make it useless for the intended uses.
Why is water contaminated?The water is polluted because of human activity, since man multiplies and needs more and more food, more water, clothing, transportation, medicine, entertainment. The burden on the biosphere and increases occur:
· Emission of toxic gases;
· Pollution from pesticides, metals, sewage;
· Accidents such as oil spills;
· Discharge of chemical waste and radioactive material;
· Decline of Freshwater maps and deeper

All pure water comes from rain, sometimes before reaching the ground gets its first pollutant load, which dissolve substances such as oxides of sulfur and nitrogen that make acid rain. Once on the ground, the water flows over the surface and infiltrates into underground layers. Is water runoff, which in the layers and farm pesticide loads of excess nutrients and in the cities carries oil products such as water, heavy metals and gasoline. The point is the pollution coming from point sources is controllable by treatment plants. But any control measures would be effective if not accompanied by provisions designed to reduce waste and recycle everything we can, that seepage water passing through municipal and industrial landfills contaminate aquifers that supply drinking water to millions.
We are facing a new challenge. The lakes and rivers may become a desert never expected. Man must respect nature, to live in harmony, meet their needs without neglecting those of future generations. Pollution, over-predation and lead to poverty and hunger. But not all is negative with respect to pollution of lakes and rivers. In the last twenty years have established many international agreements with the overriding goal of reducing water pollution, and there are already concrete achievements. However, we must be clear that time is short and that is everyone’s responsibility.
Polluting the enviroment, we will only make that the world ends soon.
