motion of wind or water. Soil erosion is one of the major concerns of modern agriculture throughout the world. The fallowing contributes to soil erosion: Misuse of land‚ Mismanagement of arable land‚ Indiscriminate felling of trees‚ Overgrazing‚ Poor soil and water management Erosion causes or Results in a: Decline in soil fertility‚ Water supply‚ Crop yields. Thus it affects the productivity of the land‚ This decreases the production of food‚ feed‚ fiber‚ and fuel

Elk (Wapiti) Preferred Habitat: The most productive habitat for elk is aspen. Aspen areas can contain and support large numbers of elk. Some other preferred habitats are oakbrush‚ mountain shrub‚ conifer‚ spruce fir‚ and ponderosa pine. Oakbrush can provide coverage and food for the elk. Most of these habitats provide coverage‚forage‚ and security for elk. Place in the food web: Below is a picture of a food web of animals in Yellowstone National Park. The elk is a primary consumer in a food

However‚ depletion of forest tree crown cover less than 90% is considered forest degradation. Causes of Deforestation: The main causes of deforestation are summarized below: (i) Population explosion (ii) Agriculture: shifting cultivation‚ overgrazing‚ cash crop economy etc. (iii) Commercial logging: cutting trees for sale as timber or pulp (iv) Poverty (v) Mining (vi) Dams (vii) Infrastructure creation for logging (viii) Forest-fires (ix) Acid rain (x) Development projects

As per U.S. EPA estimates‚ every year in the U.S‚ 1.2 trillion gallons of sewage from households‚ industries‚ and restaurants is dumped into U.S. waterways. Urbanization‚ agriculture‚ and sewage discharge are major contributors in the loss and degradation of North American wetlands‚ resulting in an increasing amount of pollutants in the waterways. A wetland is an area of land where the surface is partially or entirely covered by water‚ and is especially important in maintaining an ecological balance

to shifting climate patterns. Invasive plant species currently cover about 50% of the remaining surface of Lake Chad. Research carried out over the past 40 years indicates that the main factors in the shrinking of the lake have been: Major overgrazing in the region (Coe and Foley‚ 2001)‚ resulting in a loss of vegetation and serious deforestation‚ contributing to a drier climate. Large and unsustainable irrigation projects built by Niger‚ Nigeria‚ Cameroon and Chad‚ which have diverted water

of water cuts gullies in slopes :O! * Wind erosion – occurs in dry parts of world * What makes soil erosion worse? * Deforestation and removing vegetation. As a result of this soil gets exposed to wind/rain * Overgrazing by animals. Result is same as above * Over cultivating the soil! Especially monoculture which weakens the soil and structure and removed minerals from soil * Compacting the soil by use of heavy machinery. This encourages more

World Biomes Task 2: Main characteristics of grasslands. Grassland biomes are ecosystems predominantly consisting of a diverse range of grasses. Grasslands are generally flat terrains of rolling grass which are vast and continuous. The widespread of grasslands occurred during the Miocene and Pliocene Epochs in Western North America‚ where continental climates became favourable to grasslands as a result of the rise

brings about damage‚ which should not be neglected. So preventing sand storm is of strategic significance for human to be survival. Many methods are contributory to prevent the sand form. Sand storm is liable to occur in the arid‚ blustery‚ overgrazing and desertification area. So not having a enhanced solid can be a serious obstacle preventing human form reducing the frequency of it. Planting trees‚ enlarging the area of forest‚ and establishing the ecological barrier are the best way to strength

Environmental management can be described as the process by which the collection of policies‚ structures‚ resources‚ systems and processes are brought to mutual interplay for the achievement of clearly defined environmental policy directives (EPA). Ghana‚ a developing country‚ is facing so many environmental challenges despite the policies put in place by the various institutions to help curb this problem. Some of these challenges are lack of proper waste management‚ deforestation‚ pollution‚ land
