In many ways, we are making this planet difficult to live in. Here are five ways in which our activities are having a negative effect on our environment.

Carbon dioxide emissions
We burn fossil fuels which emit carbon dioxide. The atmospheric levels of carbon dioxide are very high now. Carbon dioxide traps gas, so the average temperature of the earth is increasing. As a result, the weather patterns are changing. Some of the carbon dioxide that are absorbed into the oceans have increased the acidity level by 30%. So, the oceanic ecosystems and the food chains are affected.
Our life depends on a lot of fresh water that is available in lakes and rivers. But one-fourth of the Earth’s basins dry up before getting into the ocean. This happens because of low rainfall which is mainly caused by deforestation and man-made dams built to divert water flow.
More than 40% of the Earth’s surface is comprised of agricultural lands. Much of this land was covered with forest. But now there is more farmland due to deforestation. Lots of carbon dioxide is emitted due to deforestation. The fertilizers that are used in farming also has negative effects on the environment. They inject a large amount of phosphorous and nitrogen into the ecosystem.
Plastics contain chemical compounds that can stay in the environment for thousands of years. It has a great impact on the ecosystem. Much of this plastic ends up in landfills and the rest goes to the ocean disrupting the aquatic life.
All these activities are caused by man and are having a severe effect on our environment. We must control these activities in order to save this planet.
