Explanation:
Pollution control is the process of reducing or eliminating the release of pollutants into the environment . It is regulated by various environmental agencies which establish pollutant discharge limits for air, water, and land.
Air pollution control strategies can be divided into two categories, the control of particulate emissions and the control of gaseous emissions. There are many kinds of equipment which can be used to reduce particulate emissions. Physical separation of the particulates from the air using settling chambers, cyclone collectors, impingers, wet scrubbers , electrostatic precipitators, and filtration devices, are all processes that are typically employed.
Settling chambers use gravity separation to reduce particulate emissions. The air stream is directed through a settling chamber, which is relatively long and has a large cross section, causing the velocity of the air stream to be greatly decreased and allowing sufficient time for the settling of solid particles.
A cyclone collector is a cylindrical device with a conical bottom which is used to create a tornado-like air stream. A centrifugal force is thus imparted to the particles, causing them to cling to the wall and roll downward, while the cleaner air stream exits through the top of the device.
An impinger is a device which uses the inertia of the air stream to impinge mists and dry particles on a solid surface. Mists are collected on the impinger plate as liquid forms and then drips off, while dry particles tend to build up or reenter the air stream. It is for this reas

Population control is important to maintain equilibrium on the planet. The population is dependent and utilises several natural resources. In case of undue increase it will put pressure on the natural resources like soil, air and water and cause their exploitation.
Human reproduction planning is the practice of intentionally controlling the rate of growth of a human population. Historically, human population planning has been implemented with the goal of increasing the rate of human population growth.
