2. Air pollutionThe air we breathe has a very exact chemical composition; 99% of it is made up of nitrogen, oxygen, water vapor and inert gases. Air pollution occurs when things that aren't normally there are added to the air. A common type of air pollution happens when people release particles into the air from burning fuels. This pollution looks like soot, containing millions of tiny particles, floating in the air.
Noise pollution: Noise pollution happens when the sound coming from planes, industry or other sources reaches harmful levels. From research, that there are direct links between noise and health, including stress-related illnesses, speech interference, hearing loss
Water pollution:Water pollution happens when chemicals or dangerous foreign substances are introduced to water, including chemicals, sewage, pesticides and fertilizers from agricultural runoff, or metals like lead or mercury. According to the Environmental Protection Agency (EPA), 44% of assessed stream miles, 64% of lakes and 30% of bay and estuarine areas are not clean enough for fishing and swimming. The EPA also states that the United State's most common contaminants are bacteria, mercury, phosphorus and nitrogen. These come from the most common sources of contaminates, that include agricultural runoff, air deposition, water diversions and channelization of streams.
Radioactive Pollution: Causes, Effects and Solutions to Nuclear Radiation. Radioactive pollution occurs when there is a presence or depositions of radioactive materials in the atmosphere or environment, especially where their presence is accidental and when it presents an environmental threat due to radioactive decay.
Visual pollution is the visible deterioration and negative aesthetic quality of the natural and human-made landscapes around people. It refers to the impacts pollution has in impairing the quality of the landscape and is formed from compounding sources of pollution to create
Light pollution, or artificial light at night, is the excessive or poor use of artificial outdoor light, and it disrupts the natural patterns of wildlife, contributes to the increase in carbon dioxide (CO2) in the atmosphere, disrupts human sleep, and obscures the stars in the night sky.
Litter adversely affects the environment. Littering along the road, on the streets or by the litter bins, toxic materials or chemicals in litter can be blown or washed into rivers, forests, lakes and oceans, and, eventually can pollute waterways, soil or aquatic environments.
