Deforestation is the permanent destruction of indigenous forests and woodlands. The term does not include the removal of industrial forests such as plantations of gums or pines. Deforestation has resulted in the reduction of indigenous forests to four-fifths of their pre-agricultural area. Indigenous forests now cover 21% of the earth’s land surface. In a forest the crowns of individual trees touch to form a single canopy. In a woodland‚ trees grow far apart‚ so that the canopy is open.

DEFORESTATION Deforestation has been described as the cutting down of trees without planting others in their place. Deforestation‚ clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms‚ ranches‚ or urban use. It is hard to think that there was a time when 90% of the earth was covered by trees‚ but this was once the case. More than half of the animal and plant

Forests are the lungs of the earth and they should not be destroyed. Deforestation causes not only the loss of our precious and stunning forests‚ but also habitat destruction‚ extinction of species‚ and the loss of necessary resources. It’s imperative to prevent the total destruction of our land so that we might be able to salvage what’s left of our environment. If we don’t stop this problem soon there will be no future for our children. Habitat destruction is the awful process in which natural

also take the carbon dioxide that is bad for us‚ and could kill us‚ out of the air‚ so that they can survive. Trees moderate global temperatures and rainfall‚ especially when in forests. They cool the earth by providing shade‚ and recycle water by helping to move rainfall along. And when trees are clustered together in forests‚ they help these natural causes to work even faster‚ because there are such a great amount of trees. The harvesting of timber to produce wood and paper products is detrimental

BIOL101 Article Review 5/1/2010 Deforestation It is impossible to overstate the importance of humankind ’s clearing of the forests. The transformation of forested lands by human actions represents one of the great forces in global environmental change and one of the great drivers of biodiversity loss. The impact of people has been and continues to be profound. Forests are cleared‚ degraded and fragmented by timber harvest‚ conversion to agriculture‚ road-building‚ human-caused fire‚ and in

LAND POLLUTION TYPE: DEFORESTATION 1. INTRODUCTION Deforestation: is the removal of trees as well as other plants from forest areas much more quickly than they can be replanted or regenerated naturally. It ’s a trouble due to the parts how the trees must play in stabilising the climate‚ atmospheric composition and soil structure. According to The Environ Facts 8 Feb. 1999‚ deforestation reduces the ability of the land to support life‚ affecting wild species‚ domestic animals‚ agricultural

Deforestation Deforestation‚ involves the cutting down‚ burning‚ and damaging of forests. The clearing of tropical forests across the Earth has been occurring on a large scale for many years. If the current rate continues‚ the world ’s rain forests will vanish soon‚ causing unknown effects on global climate and eliminating the majority of plant and animal species on the planet. It would also change the water and oxygen levels dramatically‚ which would increase the global warming. Deforestation is

Deforestation Forests are vital for life‚ home to millions of species‚ they protect soil from erosion‚ produce oxygen‚ store carbon dioxide‚ and help control climate. Forests are also vital for us to live as they provide us with food‚ shelter and medicines as well as many other useful things. They also purify the air we breathe and water that we need to survive. Deforestation by humans is causing all of these necessary functions to be lessened‚ and hence damaging the atmosphere even further. Forests

Besides‚ deforestation increases the severity of global warming. All living plants store carbon (Venkataramanan‚ M & Smitha 2011). Unfortunately‚ we are currently destroying plants which are one of the best known mechanisms for storing carbon (Venkataramanan‚ M & Smitha 2011) besides oceanic processes such as solubility pump and biological pump through the burning of forests (Michael‚ E & Selin‚ H no date).

HYDROPONICS Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions‚ in water‚ without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium‚ such as perlite‚gravel ‚mineral wool‚expanded clayor coconut husk . Some of the reasons why hydroponics is being adapted around the world for food production are the following: No soil is needed for hydroponics The water stays in the
