What impact does human activity have on climate change and global warming?

A face print.

Humans have a large impact on climate change such as building cities, driving cars, running the heater in our homes, and cutting down forests. But Humans are not the only ones to blame, I recently watched a television show that explained that the moon is getting farther away from the earth. Only a slight change in the moons' position can drastically change the earth's climate. The moon is also the one responsible for the changes of our seasons. It is has also been said that the earth goes through cycles every billion years or so, cycles in which the earth gets extremely hot or cold, Ex: the ice age.Humans need to learn to use technology to their favor and impact the world in a positive way to prevent global warming, we should start by not contributing to it.

I hope this has helped you or helped somebody else to come up with a better answer :)

THAT is the problem.

They aren't sure how much impact human activity has outside of limited area effects where people are concentrated, such as in cities.

They KNOW that "man" has SOME impact, but argue over how much and what to do about it.
