Geological theory is that the island broke away from the African continent over 150 million years ago‚ but humans did not inhabited the island until 2000 years ago (wildmadagascar.org

Deforestation has caused some rainforests to disappear completely‚ and it is estimated that over 3 million hectares of forest are eliminated each year from the region. Brazil accounts for 27% of all accounted for

sustainability of world environment. Ladies and Gentlemen‚ One of the causes of environmental damage is deforestation‚ or known as the destruction of forest. The deforestation has caused many disasters in this world‚ including Indonesia. Floods‚ earthquakes and landslides are examples of killing disasters which make us realize that the existence of forest is very important. In Addition‚ another effect of deforestation is related with the global warming or the increase of global surface temperature which is mainly

Three major causes of soil erosion There are three causes of soil erosion over cultivation‚ overgrazing‚ and deforestation. All of these causes can be corrected in different ways. Over cultivation is when the land is repeatedly tiling and producing crops faster than the soil can restore resulting in a decrease in the soil value and productivity. One of the ways that over cultivation can be corrected is by a technique called no-till agriculture. No-till agriculture is a procedure where chemicals

White 2 Deforestation Deforestation is one major issue that has been caused by human population growth. Deforestation is the loss of forest due to the act of trees being overcut. This becomes such a big issue due to a problem known as soil erosion that occurs when deforestation happens. Soil erosion is the loss of the protective top layers of soil which take away from the ability of the soil

rainforest which has already lost 20% of its area forever. Deforestation is the single biggest threat to the rainforest; the prime cause of it is cattle ranching. This is when land is cleared to provide space for cattle ranchers to herd their livestock to help increase beef production. This activity accounts for 60% of deforestation in Brazil‚ which is having a major effect on the biodiversity of the ecosystem. The impacts of deforestation are wide. In the Amazon there have been problems with increased

As a result of industrialization‚ pollution came about. Deforestation was inevitable because of the expansion of urban developments. Another big player in the Earth’s damage is global warming‚ which is getting quite a lot of attention in these recent times. Let’s take the great state of Texas‚ and where I

The world as a whole currently faces several dramatic problems. Examples of these world problems include terrorism‚ desertification‚ overpopulation‚ deforestation‚ pollution‚ and world hunger. Of all these world problems the two that should currently be focused on are deforestation and pollution. Millions of acres of forests are chopped down by large lumber companies for the means of economic success.
