Contaminacion del Suelo
Estos agresivos no solo provienen de las actividades del hombre, sino que en menor medida pueden darse mediante la llamada Contaminación Natural, originada por ejemplo en el caso de Erupciones Volcánicas, o bien en aquellos casos donde depósitos de sustancias o metales tóxicos en la tierra comienzan a ascender progresivamente hacia la superficie.
Entre los distintos causantes de este fenómeno, encontramos no solo aquellos que han sido vertidos intencional o accidentalmente por el hombre y sus actividades industriales y económicas en general, sino también a aquellas que se acumulan progresivamente hasta alcanzar niveles tóxicos que degradan al suelo, las especies que allí se desarrollan y hasta lo pueden volver infértil y no apto para cultivo.
Entre los agresivos químicos que podemos encontrar, destacamos los siguientes:
Derivados del petróleo: Hidrocarburos en general, con o sin tratamiento previo Solventes Inorgánicos y Orgánicos Pesticidas Prohibidos Tóxicos Metálicos
No solo encontramos consecuencias nocivas para el estado del suelo en sí, sino también esto puede repercutir directa o indirectamente en las reservas de agua que puedan encontrarse cercanas a la zona afectada, causando que el Agua Potable indebidamente tratada tome contacto con estos tóxicos y se acumulen en ella.
La consecuencia entonces para las personas está en su ingesta, causando problemas de salud con intoxicaciones agudas o crónicas, situación que solo puede ser revertida con un trabajo que conlleve en una delimitación, aislamiento y saneamiento de la zona (lo que lleva una gran inversión económica)

The contaminacion
When we talk about pollution do in very general terms, because something this contaminated with an agent in a medium that is not the usual and caused some instability in the balance, altering their conditions and causing unrest in diverse ecosystems, so be informed is the first thing of caring for the environment and protect it from contamination.

There are many different types of pollution because any chemical substance (organic or synthetic sea) or energy can be causing pollution, if we them present in environments in which non-originating son, as it is the case in the light of the cities at night, they can achieve such intensity baffle an animals, being one of the major cases of light pollution.
Son considered polluting agents exceed natural levels and capable of affecting the life and the ecosystem, although any strange media agent is undesirable.
The types of pollution, the most common and worrying son:
One of the key measures we can take to alleviate planet pollution from our own homes is recycled and organizer better waste, already badly rendered garbage tends to be the main cause of not industrial pollution.
Use products biodegradable as ecological detergents also is recommended, as well as trying to use green energy with no impact on the environment.

Contaminacion sea
Often think that the sea takes it all, and partly is thus unfortunately what if son our waste, Trash and debris, cause them pollution in their waters and mainly affect marine life and specs a species in danger of extinction.

Main not seawater son pollution-causing agents hydrocarbons such as oil and indeed to be soluble in water can stay long and even get an of para coastline contaminate Earth, spreading contamination.
Waste and discharges, mainly industrialists, cast into the sea causing severe disorders to aquatic life, already not only of choking and kills a fish but also eradicates the marine flora avoiding settlements of fish and ecosystems.
What is worse man uses the sea as exploitable resource, for example through fishing, by thing ourselves we consume fish envenenamos affect us directly.

The atmospheric contaminacion
Pollution, air pollution or air pollution can be one of the more damage you are doing to the planet, their side effects already affect not just an isolated areas or ecosystems, but the Pope with sheer as global warming, world by become it aware about his men is a priority, and the reason for this entry.

Air pollution occurs when substances or energy mezclan l gas and disturbing the balance thereof, by altering natural, attacking various materials, reducing visibility, hindering biological such as respiration and photosynthesis process conditions, as also cause diseases or produce unpleasant odors.
The main causes of pollution of air due to processes involve combustion, industrial processes, the engines of vehicles or residential heating already generate carbon dioxide, carbon monoxide, oxides of nitrogen and sulphur, among several other gaseous pollutants.
Once his, some industries also emit gases harmful during their production processes, as e.g. chlorine or hydrocarbons not made completely, combustion being toxic substances threaten life directly.
This pollution can have a local character, but as we mentioned, global warming is an alterations in the greenhouse effect due to pollution of the air that leaves the Sun's rays pass freely.

Environmental contaminacion
One of confusions more common on environmental contamination is to think that just about air pollution, when this is only one of the concept of environmental pollution, including types of pollution by will try it to explain it better, certainly by the definitions of the words for a better understanding.

Contamination occurs when external media agents entering it and achieve change or alter it, as for example spills of oil at sea, is one of the examples more clear about the contamination of water and bring dire consequences for marine life. But it is there where we will define what is the environment. In the case of the example above, the affected environment is the sea, while the air remains Sin contaminated, a less burn oil as a form to contain the spill and forming gases achieve air pollution zone, unfortunately is a "solution" more common.
I defined these terms we can say the environmental pollution subject one different zones, ecosystems, areas, and means, being this contamination directly affects it the environment and life on the planet.
There are many ways to combat pollution and help care for the environment, use products biodegradable, recycled at home, do not use plastic bags, encourage the use of returnable containers, not places by throwing trash in unfit to remain where Sin treatment or inclusive to try taking a penchant for green energy, e.g.
