My second Inquiry Into

My second inquiry is: How human activity changes the CO2 level. Human does things that cause more CO2. One of the things that human do is deforestation. Deforestation causes a lot of consequences. One of them is the carbon cycle. Forests store carbons because trees take CO2 from the atmosphere. Trees use it to produce the carbohydrates, fats, and proteins that make up the tree. When forests are cut down, and the trees are destroyed, the carbon they keep is released as CO2. If more trees are destroyed it means more CO2 are released back into the atmosphere. Deforestation happens because people want more space to make factories and other things.

Human activity also causes air pollution, and most of the air pollution is CO2. Air pollution is created by burning rubbish, smoke from the factory and also using cars that have many smoke coming out of it. There are not only air pollution, but also pollution in water and land. Sometimes people throw soda cans into the rivers. There are soda left on the cans, and that’s why the water is polluted. The water’s pH is changed by the CO2. If humans are not careful with what they are doing, they can bring bad luck to themselves in many ways.
