pollution

Pollution:

 is the introduction of contaminants into the natural environment that cause adverse change.^[1] Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed 9 million people in the world.

Major forms of pollution include: Air pollution, light pollution, littering, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, water pollution.

Certain gases in the atmosphere can cause air pollution. For example, in cities, a gas called ozone is a major cause of air pollution. Ozone is also a greenhouse gas that can be both good and bad for our environment. It all depends where it is in Earth’s atmosphere.

How doos air pollution affect Earth’s climate?

Aerosols can impact how the Sun’s light hits Earth. For example, some aerosols reflect sunlight while others absorb sunlight. It depends on the color of the particl

Dark surfaces—whether it’s a black t-shirt or a dark particle in the atmosphere—absorb the Sun’s heat. Lighter-colored surfaces reflect heat from the Sun.

A white t-shirt reflects the Sun on a hot day, making you feel cooler. In the same way, light-colored particles that reflect the Sun’s light and heat away from Earth can make the global temperature cooler. Dark-colored particles that absorb the Sun’s light can make the global temperature warmer.

My opinion on the issue of pollution
The problem of pollution is a big and dangerous problem that pollutes the air and the environment harms us humans a lot, because the environmental pollution found in the streets and cities may cause pollution in the atmosphere as well. This is very dangerous, so I hope that this pollution will decrease everywhere so we must start in our streets and homes. And our cities in order not to cause a threat to our lives
