Make a Difference” Living in a country with rapidly growing population‚ conservation is an increasingly pressing matter. This dilemma is more prevalent in times of drought. Individuals have to play a part to manage water and to keep from soil erosion. However‚ making a population do something is a difficult objective to achieve. I offer a solution in three ways: one‚ that a fine is imposed on citizens that go over a certain amount and two‚ we make appliances and water efficient farming the

The trees around us are extremely important and have always been necessary for improving the human condition - both during its life and after harvest. It is not a stretch to believe that without trees we humans would not exist on this beautiful planet. In fact‚ some claim can be made that our mother’s and father’s ancestors climbed trees - another debate for another site. So‚ trees are essential to life as we know it and are the ground troops making up an environmental frontline. Our existing forests

estimated that half of the forests have been cut down to provide fuel wood and land for the grazing of livestock and arable agriculture so that farm terraces could be extended. The cuttings down of trees have resulted in severe deforestation‚ soil erosion‚ poor catchments management and severe land degradation on steeply sloping land ensued. In the Middle Hill region‚ Australian field staff discovered barren hill slopes‚ deeply incised with gullies and excessive rates of runoff. After heavy rainfalls

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

It includes the adverse effects of overgrazing‚ excessive tillage‚ erosion‚ sediment deposition‚ extractive industries‚ urbanisation‚ disposal of industrial wastes‚ decline of plant communities‚ and the effects of noxious plants and animals.

connection between sediment aggradation‚ erosion and climate in a desert environment of the Majes valley‚ southern Peru. Luminescence dating of terraces and fans shows that sediment aggradation correlates with wet time intervals on the Altiplano‚ suggesting a climatic influence on the aggradation–degradation cycles. Major periods of aggradation occurred between *110–100‚ *60–50 and 12–8 ka. More precipitation in the Majes catchment resulted in increased erosion and transportation of sediment from the

during a flood‚ much larger boulders can be moved. The Hjulström curve illustrates the relationship between velocity and competence. It shows the velocities at which sediment will normally be eroded‚ transported or deposited. The mean or critical erosion velocity (also known as entertainment velocity) shows the velocity required to pick up and transport sediments of varying calibre. The mean fall or settling velocity curve indicates the velocity at which each calibre of sediment is deposited because

However‚ forests prevent soil erosion‚ landslides‚ and flooding; maintain the purity of the air and water; affect local and global rainfall.

The emerging trends of deforestation‚ desertification and soil erosion are closely linked with societal basic needs‚ economic and population growth and energy consumption-making the entire issue very complex. As increasing number of small farmers and rural poor are considered as destroyers of forests‚ and the solution

I think that the first thing that needs to be done to help combat world hunger is education. People in developed countries need to realize that hunger is a problem. As they always say‚ acceptance is the first step. However‚ this obviously won’t be fixing any problems. But I think first is to devise a way to limit our waste. We currently have so much food that is just thrown away. It’s inevitablethat not all food will be saved: some will be thrown away‚ but if we could utilize more of this food into
