Causes of the danger of extinction | The habital loss

The loss of Habitat is one of the causes more common by which mainly animals are in danger of extinction, since they cannot remain in their native homes either are forced to adapt to new ones.

The plants and animals also need water, food and shelter to survive, worse unlike humans, adaptation can be very difficult, since they do not have the means and capabilities to collect or eat other foods, purifying and water storage or build shelter and shelter.

Habitat loss can be due to causes natural as well as artificial, for example, an earthquake or tsunami can destroy plants and trees necessary for bird birdhouse, but also helicopters and human activities can deter these birds or insects which feed on.

It should be noted that natural habitats need not be completely destroyed so that the species can not continue living there, given that to live in an ecosystem, if removed a vital part of this system, the other also crumbling.

Causes of the Danger of Extinction

Another of the main causes of many plants and animals from entering endangered are human activities that attack them directly or indirectly.

In the case of the exploitation of animals for their meat or skins, had taken several steps around the world, but on the black market prices are still very high, so poachers continue species to their destruction.
While this is a direct way of attacking species, the machinery and the disturbances such as noise pollution that cause humans and their machines, they attack indirectly complete ecosystems.

A clear example of this are the helicopters in tourism such as waterfalls and rainforests locations, where birds can not tolerate noise and are forced to leave the area.

The Golden Eagle is an example of this, given ben constant disturbances during its nesting have achieved their reproductive capacity has decreased alarmingly.

Pollution Atmosferica Leading Causes

There are many causes of air pollution, but we can name some of the more common throughout the world, with its activities and emissions.

Refinery in oil
Activity: Refined petroleum and derivatives, such as fuels and lubricants substances manufacturing.
Emissions: carbon dioxide, methane, sulfur dioxide, hydrocarbons.
Effects: Cardiovascular and respiratory, eye irritation, carcinogenic properties, effect greenhouse and acid rain. Carbon dioxide, methane and oxides of nitrogen are important greenhouse gases. The oxides of nitrogen and sulphur are the cause of acid rain threatening all the forests of the Earth.

Chemical industry
Activity: Production of chemicals from various raw materials.
Emissions, sulfides, sulphur dioxide, carbon dioxide, organic and inorganic compounds.
Effects: carcinogenic properties and mutagenic, cardiovascular, respiratory and skin complaints, pestilence and different toxicities.

Incineration of waste
Activity: urban solid waste disposal
Emissions: sulphur oxide, various organic substances, hydrochloric acid.
Effects: cardiovascular, respiratory and central nervous system, carcinogenic properties and acid rain.

Pollution Atmosferica

Continuing with the first part of the main causes of air pollution

Livestock facilities
Activity: farming
Emissions: methane, ammonia
Effects: power as greenhouse of the methane gas is 20 to 30 times greater than carbon dioxide, which is certainly is a big problem

Thermal power stations

Activity: production of electricity from fossil fuels
Emissions: sulphur dioxide, nitrogen dioxide, carbon monoxide, carbon dioxide
Effects: diseases cardiovascular, disturbance of the transport of oxygen in the blood, respiratory problems, greenhouse effect, acid rain (oxides of nitrogen and sulfur that we send into the atmosphere are mixed with the steam of the clouds and returns to Earth as acid rain)

Cars
Activity: excessive use of transportation in city and highway
Emissions: carbon monoxide, dioxide, nitrogen, hydrocarbons, lead, and others
Effects: alteration of the transport of oxygen in blood, respiratory, carcinogenic properties, kidney and central nervous system.
