The inhabitants of major cities of Bangladesh are also exposed to high level of noise pollution. Environmental degradation of Bangladesh is also caused due to poverty‚ over-population and lack of awareness on the subject. It is manifested by deforestation‚ destruction of wetlands‚ soil erosion and natural calamities. DIFFERENT

What Is Soil Pollution? Soil pollution comprises the toxic waste of soils with resources‚ mostly chemicals that are out of place or are present at concentrations advanced than normal which may have unpleasant effects on humans or other organisms. However‚ soil pollution is also caused by resources other than the undeviating addition of man-made chemicals such as undeveloped runoff waters‚ industrial waste materials‚ acidic precipitates‚ and radioactive clash. Both organic and inorganic contaminants

Due to the high demand of needs of native people in Madagascar‚ they have been forced to use the country’s natural resources to survive. Deforestation and soil erosion are the main reason why many notable species have already vanished. Twenty-two percent of the total land of Madagascar had

Causes of Floods Floods are caused by many factors: heavy precipitation‚ severe winds over water‚ unusual high tides‚ tsunamis‚ or failure of dams‚ levels‚ retention ponds‚ or other structures that contained the water. Periodic floods occur on many rivers‚ forming a surrounding region known as the flood plain. During times of rain or snow‚ some of the water is retained in ponds or soil‚ some is absorbed by grass and vegetation‚ some evaporates‚ and the rest travels over the land as surface runoff

Western Oregon is a region that is threatened by landslides that can cause hazards to the public’s safety‚ their natural resources‚ and infrastructure. The most hazardous areas are in the mountain terrains. Landslides are a common occurrence in Western Oregon. They can be very devastating to homes and businesses and each year millions of dollars are spent repairing the damage caused by landslides (Hofmeister‚ 2002). Landslides are not individual events‚ they occur in conjunction with other factors
