One human activity that affects the deciduous forest is how they cut down trees. Some people bring in huge machines (bulldozers) into these forests, without caring how much they destroy the environment. We sometimes cut down trees and don't replant them. This is a huge destruction to the environment. Think about how many people cut down trees. About half of those people cut down trees with no care and don't replant them. That is one way humans affect deciduous forests.
Another human activity that affects the deciduous forest is how people liter. Some people just drink a can of beer, soda, juice, etc. throw it on the ground, and don't even bother picking it up. Some people used to dump garbage in a hole. They would either burn the garbage or bury it under the soil. When they burned it they'd pollute the air, and when they buried it something bad (oil, bad water, etc.) in the garbage could've gotten into the root system of a tree/plant and killed it. There is another way human activities affect the deciduous forest.
The third way humans affect the deciduous forest is how they “accidentally” drop oil into the soil. That is a horrible destruction to the deciduous forest, because if it gets into a tree/plants system it can easily kill it. People now-a-days still have sewer pipes leading into little ponds in the forest. That also can kill trees. That's human affect to the deciduous forest I'm going to talk about.
