Humans and the Environment - Making an Impact

Deforestation

Deforestation is when people remove trees for resources and flat land. Tropical rain forests is where the most intense deforestation is. One example is the rain forest in Brazil. One downside from cutting down trees is that animals lose their habitats.

Acid Rain

Acid rain is when moisture in the air mixes with air pollution. This harms plants, animals, humans, and the whole environment. Acid rain flows towards lakes and effects the water and the animals living in that body of water. The pH level in the water drops, which causes fish and other animals have a hard time surviving. Forests in Germany like the Black Forest and China are suffering from acid rain. 

What is Acid Rain

Desertification

Desertification is when the desert spreads because of over grazing in the Steppe by animals, like the Sahara. The Sahara is getting larger and larger and this effects many people and how they live and adapt to their environment. It effects them by taking away their main source of water, which effects their farms. It effects the animals by them not having water to drink and grass to graze on. 

Hurricane Matthew

A hurricane is a major tropical storm that originates in the Atlantic Ocean. Hurricanes effect humans in many ways. They destroy their homes and many trees fall because of the strong winds formed by the hurricane. Hurricane Matthew is happening right this moment and it is currently a category 3 hurricane. Hurricane Matthew has killed about 1,000 people in just Haiti. About 19 people so far in the U.S. have died. More than 3 million people have been evacuated from Florida.
