DEFORESTATION
Deforestation is a process usually caused by human action, which destroys the forest area.It is directly caused by the action of man over nature, mainly due to logging or burning by the industry timber and to obtain land for farming and ranching.
Efficiently remove trees without reforestation, results in serious damage to habitat, biodiversity loss and dryness. Has an adverse impact on the fixation of atmospheric carbon (CO2). Deforested regions tend to soil erosion and degrade often unproductive land.
Among the factors that lead to large-scale deforestation include: the neglect and ignorance of the intrinsic value, the lack of value attributed irresponsible management of afforestation and weak environmental laws.
In many countries extinction because of deforestation, changes in climatic conditions, desertification and displacement of indigenous peoples.

DEFORESTACIÓN
La deforestación es un proceso provocado generalmente por la acción humana, en la que se destruye la superficie forestal. Está directamente causada por la acción del hombre sobre la naturaleza, principalmente debido a las talas o quemas realizadas por la industria maderera, así como para la obtención de suelo para la agricultura y ganadería.Remover árboles sin una eficiente reforestación, resulta en un serio daño al hábitat, perdida de biodiversidad y aridez. Tiene un impacto adverso en la fijación de carbono atmosférico (CO2). Las regiones deforestadas tienden a una erosión del suelo y frecuentemente se degradan a tierras no productivas.
Entre los factores que llevan a la deforestación en gran escala se cuentan: el descuido e ignorancia del valor intrínseco, la falta de valor atribuido, el manejo poco responsable de la forestación y leyes medioambientales deficientes.En muchos países la deforestación causa extinción, cambios en las condiciones climáticas, desertificación y desplazamiento de poblaciones indígenas.
Acid rain is formed when moisture in the air combines with nitrogen oxides and sulfur dioxide emitted by factories, power plants and vehicles that burn coal or petroleum products. Interacting with water vapor, these gases form sulfuric acid and nitric acid. Finally, these chemicals fall to earth accompanied by the precipitation, forming acid rain.
The primary air pollutants that give rise to acid rain can travel long distances, being transported by winds hundreds or thousands of miles before precipitating in the form of dew, rain, rain, hail, snow, fog or mist. When precipitation occurs, can cause great damage to the environment.

LLUVIA ÁCIDA
La lluvia ácida se forma cuando la humedad en el aire se combina con los óxidos de nitrógeno y el dióxido de azufre emitidos por fábricas, centrales eléctricas y vehículos que queman carbón o productos derivados del petróleo. En interacción con el vapor de agua, estos gases forman ácido sulfúrico y ácidos nítricos. Finalmente, estas sustancias químicas caen a la tierra acompañando a las precipitaciones, constituyendo la lluvia ácida.
Los contaminantes atmosféricos primarios que dan origen a la lluvia ácida pueden recorrer grandes distancias, siendo trasladados por los vientos cientos o miles de kilómetros antes de precipitar en forma de rocío, lluvia, llovizna, granizo, nieve, niebla o neblina. Cuando la precipitación se produce, puede provocar importantes deterioros en el ambiente.
THE USE OF PESTICIDES
When we talk about the pollution of land, we refer to the contamination of soil in particular, which occupies only 1 / 4 of the total surface of our planet, but it is the part where I live most of the land creatures, and between including humans.
Soil contamination occurs mainly in the presence of chemical compounds or alterations to the natural soil environment. This is due mostly to the use of pesticides and other chemicals that are absorbed by the soil, which causes mixing between its components and when plant life is growing, it absorbs these components dying or transporting them to humans who ingest them.
Leaks waste build sanitary and industrial products are also causes of soil contamination. Petroleum products, solvents and heavy metals are the most common chemicals that are absorbed by the earth.
Soil contamination can be a very serious problem as there are many layers of underground water being extracted for human consumption, and these layers are in contact with the ground, and if it is contaminated, these components are usually absorbed by water .
The soil cleanup is very costly and difficult to carry out, as recommended, is to try not to smudge or contamination in the beginning, mainly avoiding littering and chemicals in undesignated places

USO DE PESTICIDAS
Cuando hablamos de la contaminación de la tierra, nos referimos a la contaminación del suelo principalmente, que ocupa tan sólo 1/4 de la superficie total de nuestro planeta, pero es la parte en la que habitan la mayoría de las criaturas terrestres, y entre ellas el ser humano.
La contaminación del suelo se produce principalmente con la presencia de compuestos químicos o las alteraciones del ambiente natural del suelo. Esto se debe en su mayoría al uso de pesticidas y otros químicos que son absorbidos por el suelo, haciendo que se mezclen entre sus componentes y cuando la vida vegetal trata de crecer, absorbe estos componentes muriendo o transportándolos a los seres que las ingieren.
Las filtraciones de los desechos sanitarios y la acumulación de productos industriales también son causas de contaminación de la tierra. Los derivados del petróleo, los solventes y los metales pesados son los químicos mas comunes que son absorbidos por la tierra.
La contaminación del suelo puede ser un problema muy grave ya que hay muchas napas de agua subterráneas que el ser humano extrae para consumo, y estas napas están en contacto con el suelo, y si este está contaminado, estos componentes suelen ser absorbidos por el agua.
La limpieza del suelo es muy costosa y difícil de llevar a cabo, por lo que se recomienda, es tratar de no ensuciarlo ni contaminarlo en un principio, principalmente evitando tirar basura y químicos en lugares no designados.
