Examine one cause and one effect of overpopulation referring to examples you have studied. Overpopulation occurs when there are not enough basic resources in an area to support the population. Basic resources include food‚ shelter‚ clean water‚ fuel and farmland. The main cause of overpopulation I will discuss is: High birth rates with the effect lack of food I will base my answer on the studied region of Sudan‚ Africa Cause: High birth rates Overpopulation has occurred in Sudan because of high

storms were caused by severe drought and poor farming techniques such as no crop rotation. They dug to deep into the ground‚ which destroyed all of the roots and grass in the ground that holds the soil down. Having too much agriculture‚ planting‚ overgrazing‚ and harsh winters were too much for the land to handle. Farmers also did not use the correct methods for the environment‚ which caused erosion. For example cotton farmers cleared fields and left them for the winter months. Winds are the highest

Traditional agriculture requires massive forest and grassland removal to obtain land necessary to farm on. Deforestation and overgrazing has caused erosion flooding‚ and enabled the expansion of deserts.

makes it very difficult for a viable ecosystem to establish itself and flourish. Main causes: Natural hazards are excluded as a cause of land degradation‚ however human activities can indirectly affect phenomenon such as floods and bushfires. Overgrazing by livestock can lead to land degradation. Land clearances such as clear cutting and deforestation have a big impact on Nauru. Agricultural reduction of soil nutrients through poor farming practices are also a major cause of degradation. Strategies:

How does coastal development impact the reefs? http://www.givethereefabreak.org/reef-facts/ * The growth of coastal cities and towns generates a range of threats to nearby coral reefs. * Where space is limited‚ airports and other construction projects may be built on land reclaimed from the sea. * Sensitive habitats can be destroyed or disturbed by dredging activities necessary for these developments. * Dredging for deep-water channels or marinas‚ and the dumping of waste

Ecologists recognized the important role this keystone predator species once played in parts of the West and the Great Plains. Disrupting the Ecosystem Due to the over hunting of the gray wolfs‚ large numbers of vegetation was destroyed due to overgrazing of herd animals that the gray wolf once hunted. This caused soil erosion‚ threatened other wildlife species that depended on vegetation for survival‚ and beavers who were essential to the wetlands. According to Miller‚ T.‚ Spoolman‚ S.

Without hunters there could be more motor vehicle accidents involving injuries or death to both animals and humans. Also‚ by keeping the animal population in control it prevents overgrazing which can lead to other species from dying off due to a lack of food.

droughts and occasional heavy rains. A large number of the travelers settled down in this area and built farms and ranches. These lands used led to soil exposure and great erosion. The cattle ranches were very pleasing for the settlers; this led to overgrazing and humiliation of the soil. Farmers began to plow the natural grass cover and plant their own crops. Without the original root systems of the grass to anchor the soil‚ much of it blew away. The wide row crops were very dreadful because between
