The major types of pollution include air pollution, water pollution and land pollution. Air pollution is the contamination of the atmosphere mainly due to smoke from vehicles, factories and forest fires. Water gets polluted when toxic substances like chemicals and plastic waste are discharged into the water bodies, and the process by which accumulated solid and liquid waste contaminate the soil and groundwater are referred to as land pollution.

All of them affect the Earth’s lifespan to a great extent because they tamper with the normal and healthy conditions of the Earth’s environment, which in turn questions the scope of survival of all its inhabitants.
