Essay On Environment Pollution In Bangladesh

https://essayparagraphs.com/

Bangladesh is now apparently in the grip of all sorts of pollution like air pollution, soil pollution and water pollution. The people of the urban areas are the worst suffers of such pollution. The indiscriminate industrialization process in Bangladesh over the past decades has created serious environmental problems.

Causes of pollution:

Air pollution comes from a wide variety of sources. In Bangladesh poisonous gas exhaust from industrial plants, smoke from brick fields, old vehicles and dust from roads and construction sites are some of the major sources of air pollution. We can reduce this type of pollution by making less use of motor vehicles and avoiding the use of vehicles older 20 years. We may also use proper lubricants to lessen the level of emission and pollutants.

Water pollution can occur in oceans, rivers, lakes, ponds and underground reservoirs. As different water sources flow together, the pollution can spread easily and quickly. Causes of water pollution are increased sediment from soil, erosion, improper waste disposal and littering, leakage of soil pollution into water supplies and organic materials etc. In fact, polluting the land means polluting the water. Throwing away a toxic substance on the ground near a water space means that it eventually reaches a body of water. As a result, the water is polluted. Industrial wastes must not be disposed in rivers of lakes.

We need to be more careful about disposing household wastes too. Use of pesticides means that when it rains on the lawn or garden, chemicals are washed into the water bodies. Therefore, we must be aware of the dangers of using pesticides as they may pollute our rivers, canals and lakes.

The worst cause of soil pollution is the enormous volume of industrial waste which is being produced everyday but not disposed properly. The mismanagement of household wastes, particularly the polythene shopping bags, has caused serious threat to the soil and the drainage system. Another cause for soil pollution is the use of agricultural pesticides, fertilizers etc. Sometimes fuel leakages from automobiles may get washed away by rain and seep into the nearby soil. Pesticides and fertilizers are useful for plant growth but their overuse has led to soil pollution.

Natural fertilizers and compost can be used instead of their chemical alternatives. Recycling is another way to reduce and control soil pollution. Recycling papers, plastics and other materials reduce the volume of refuse in landfills. Deforestation also causes erosion, pollution and the loss of fertility in the topsoil. Planting trees and re-forestation helps preventing soil erosion and pollution.
