Pollution in cities are increasing day-by-day. Let us find the reason of this increase in pollution.
Dense population: Big cities are densely populated because there is less space and more people using all the available air, water and buildings. When there are more population they need more houses. So, there is overcrowding. Uses of vehicles also increase along with the population.
Deforestation: To make space for more houses, roads, schools, hospitals, markets, etc. trees are cut down this causes air pollution. When trees are less pollution is more.
More vehicles and factories: The greater population uses many more vehicles that give out harmful gases and poisonous smoke to pollute the air. The increasing number of factories is making this problem worse.
Why is pollution in our environment increases so fast?
Due to unhealthy habits pollution in our environment increases so fast. Some of us are also responsible for this. People throw the waste from their house in open places and rivers etc. This causes land and water pollution. Some of us smoke use defective vehicles which give out dense poisonous smoke. All these unhealthy habits are increasing air pollution to a great extent.
Many of us are fond of using loudspeakers, horns, stereos, etc. which causes noise pollution. Noise pollution is very harmful for our physical and mental health.
