What’s the Environmental Pollution ? Environmental pollution are combination of two words. These are - Environmental Pollution

Environmental Environmental is a word. It’s source from Environment. It’s means – the natural world in which people, animals and plants live. So, Environmental means – connected with the natural conditions in which people, animals and plants live.

Pollution Pollution means – the process of making air, water, soil etc. dirty. It is harmful for natural world.

Read the Text Bangladesh is now apparently in the grip of all sorts of pollution like air pollution, soil pollution and water pollution. The dwellers of the urban areas are the worst sufferers of such pollution. The indiscriminate industrialization process in Bangladesh over the past decades has created significant environmental problems. We will now know about some of the most common types of environmental pollutions and ways of coping with them. Air pollution Air pollution comes from a wide variety of sources. In Bangladesh poisonous exhaust from industrial plants, brick kilns, old or poorly – serviced 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 order than 20 years. We may also use proper lubricants to lessen the level of emission and pollutants. We can encourage people to use Compressed Natural Gas (CNG) or Liquid Petroleum Gas (LPG) for fuelling their cars. The government may relocate hazardous industries like brick kilns to areas away from human habitations.

Water Pollution 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 include:  Increased sediment from soil  Erosion  Improper waste disposal and littering  Leakage of soil pollution into water supplies  Organic materials that decay in water supplies etc. In fact, polluting the land means polluting the water. Throwing away a toxic substance on the ground near a water space means it eventually reaches a body of water. As a result, the water is polluted. Industrial wastes must not be disposed in rivers or 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, wash into the water bodies. Therefore, we must be aware of the dangers of using pesticides as they may pollute our rivers, canals and lakes.
