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.

embankment as a result of water moving through the soil structure. If the seepage forces are large enough‚ soil can be eroded from the embankment or foundation. Seepage can also develop behind or beneath concrete spillways or headwalls. The signs of this type of problem could be cracking or heaving. Freezing and thawing will amplify the affects of seepage on concrete structures. The rate at which water moves through the embankment depends on the type of soil in the embankment‚ how well it is compacted

Intensive farming is a way of producing vast amounts of crops by using numerous chemicals and machines. These practices include growing high-yield crops‚ using fertilisers‚ pesticides and keeping animals indoors. Food production is increased however there are various advantages and disadvantages of this particular method. An example of this method would be conventional chicken farming. This method may be used by farmers due to predators e.g. foxes killing their free range chickens‚ minimising their

Abstract: Soil serves as one of the basic medium of life as a variety of elements‚ which are vital to life are embedded in it. However‚ the human activities are polluting the soil unintentionally. Consequently‚ a wide range of contaminants enter the soil. Nevertheless‚ heavy metals are the most toxic of all the pollutants. Among these‚ lead‚ cadmium‚ chromium‚ mercury and arsenic are most toxic and can cause multiple organ damages even when present in small amount. Although‚ these elements are necessary
