majority of people have come to know this term; deforestation is the clear cutting or total removal of trees in a forest. With the destruction of these luscious and plentiful forests come many environmental issues ranging from global warming to soil erosion to loss of habitat. By the end of this report you should have a better understanding of the impact of deforestation and what has to be done in Canada ’s Boreal Shield (ecozone) and of that on the Pacific Coast. The clear cutting of forests has existed

little water in the river giving it less energy to change the depth of the channel by erosion. As you go downstream the volume/amount of water (also known as discharge) also increases because more and more tributaries join the main river. The increase of water makes the energy levels rise when theres moe energy there is more erosion (in the form of abrasion‚ attrition and hydraulic action). these types of erosion erode away at the river bed creating a deeper channel. Whilst the depth varies downstream

Extensive land clearing is a problem in Australia‚ New Zealand and Tasmania. History For the most part‚ land clearing has been utilized to make way for agricultural and urban development. In the past‚ governments and people thought that if

1. Why is Mappleton threatened by coastal erosion? The plain of Holderness did not exist before the Ice Age. It was once a wide bay backed by chalk cliffs running from Flamborough Head to Hessle‚ west of the city of Hull. Today Holderness is made up of glacial tills – sands and clays deposited by ice sheets during the Ice Age (Figure 4). The tills are soft and unstable and have little resistance to erosion. The low cliffs repeatedly slump down along rotational slip planes‚ lubricated by water which

EFFECTS OF URBANIZATION IN JAMAICA Urbanization refers to the shift of population from rural areas to cities or towns according to the Encarta Encyclopaedia. In Jamaica today‚ urbanization is a constant process for persons to move from one area to the next without hesitation compared to the previous generations. Urbanization has seen a significant increase over the years because of persons pursuing a better standard of living. People move because of the economic situation of the country which

Resources are defined as a means of meeting a need‚ particularly an economic or social need‚ of the people. The term usually refers to natural resources like land‚ water‚ air. Natural resources are largely unchanged materials of the land that are valuable to people and used in variety of ways. Pakistan is rich in natural resources. It has mountains‚ plains‚ deserts‚ fertile soils‚ rivers and oceans. Natural Resources are very important for the development and prosperity of a country. The important

contribute to the devastation of nature. Overgrazing and groundwater pumping are some of the activities that damage the land. Overgrazing is one cause of soil erosion‚ in which it turns grassland into desert where soil is eroded and becomes harder for plants and trees to grow in that area which will affect the lives living there. Soil erosion is a natural process but it becomes a problem when human activity causes it to occur much faster that under natural conditions. Groundwater also contributes

The upper course of the river starts at the source of the rivers channel. The upper course of the river is shallow and has a narrow river channel due to vertical erosion caused by hydraulic action and corrosion. It also has an uneven steep river bed due its bedload as it is large boulders as they have rough edges. This then gets transported through the upper part of the river by traction. In addition some of the bedload also gets transported by suspension and little in siltation. As the river flows
