While the top 10 environmental issues can vary according to individual viewpoint, there are common threads that bind them. For example, a lack of clean water is a big concern. It also affects the health of humans, wildlife, and oceans.
Deforestation and overfishing have led to the extinction of many species. These include amphibians, birds, fish, and mammals.
Another problem is overpopulation. The human population is increasing rapidly. This means more pollutants. In fact, 90% of the world’s population breathes in air that is contaminated with pollutants.
One of the biggest sources of air pollution is motor vehicle exhaust. Other sources are factories and industries.
Air pollution is a leading environmental issue, and it threatens the life of almost all people on Earth. The WHO estimates that at least one in nine deaths worldwide is caused by air pollution.
Pollution also leads to the deterioration of the ozone layer. The ozone layer helps protect the earth from harmful UV rays. Without it, we would be exposed to cancer-causing radiation.
Sea level rise is another major environmental problem. During the past 100 years, global sea levels have increased by eight inches. Oceans have been damaged by fuel spills and dumping of pollutants.
The ozone layer has been destroyed by CFCs, which are used in everyday life. The chlorine in these gases destroys the ozone layer.
Acid rain is also a major problem. This occurs when nitrogen oxides, sulfur dioxide, and other pollutants are emitted into the atmosphere. When acid rain falls on the ground, it is a huge threat to humans, wildlife, and aquatic species.
