Deforestation.

http://slidepdf.com/reader/full/enviromental-degradationana-araceli1 4/18

Why are people clearing so many forests and  

rainforests around the world?  

The biggest factors that contribute to deforestation

are farms and cattle pasture. In many countries thepopulation is growing, and the people

need more and more space to expand,

so many forests are cleared out.

Problems that are affecting the

degradation of soil.Pressures on the region's agricultural land are leading to

extensive land degradation: the causes are poverty, land

shortage and increasing populations. It also has toocontaminated places.

Atmospheric issues.

The most common issues in the atmospheric are:

-The contamination of the air and global warming: the

pollution in the cities is higher because of industries pollution the

air. The result is climate change.

- Acid rain: it is a rain that is unusually acidic. It eects

to the plants, aquatic animals and infrastructures.

- The thinning of the ozone layer: it's getting smaller

because of the pollution.

Main causes of water

degradation.Water degradation is the contamination of water bodies, like

lakes, oceans or rivers.

There are two problems:

-Over exploitation: it is the excessive consumption of fresh

water for agricultural, urban or industrial uses.

- Contamination: It is caused

by chemical products,

discharges and spillages from

industries.

Degradation to the loss of 

biodiversity.Biodiversity is the variety of animals and plant species on

the Earth.

Causes of the loss of biodiversity:

-Alteration and loss of the habitats.

-Introduction of exotic species andgenetically modied organisms.

-Pollution.

-Climate change

-Overexplotation of resources.

Brazil.

Brazil has got the highest deforestation rate in the world.

Over 600,000 square kilometers of Amazon rainforest

have been destroyed. It is caused by:

1 Cattle ranching and infrastructure.

  2 Hydroelectric dams and mining activities.

  3 Soybean production.

Ukranie: Chernobyl. 

Chernobyl accident is one of most important

atmospheric issues, an explosion and re released

large quantities of radioactive particles into theatmosphere leaving serious consequences. Today,

no one can live there.

Thailand.Between 1945 and 1975 forest cover in Thailand

declined from 61% to 34% of the country's land area

because of deforestation. The main causes are:

1 Population growth.

2 Agricultural policy.

3 Illegal logging.

 Japan.Light pollution is common in Japan, New York and other

cities because there are a lot of people living there. Some

consequences are:  1 Energy waste.

2 Eects on animal and human health and psychology.

3 Disruption of ecosystems.

4 Eect on astronomy.

  5 Increase in atmospheric pollution.

New Zealand.

Water pollution in New Zealand is linked to a siltation due to

land clearance who has aected lakes, rivers, caves and bays.
