How have human activities effected the air in earth’s atmosphere?

Human activities have had a negative impact on Earth's atmosphere.

Explanation:

Human activities, since the Industrial Revolution, have gradually been having more and more influence on Earth's atmosphere. As more and more the economies have developed, the bigger and bigger the output of gases into the atmosphere. The gases that are released into the atmosphere are mostly greenhouse gases, but there are also some that are highly toxic.

This has contributed to a sharp increase in CO2 levels in the atmosphere, which is speeding up the process of global warming, and that can have devastating consequences for life on Earth. Also, some of these gases managed to cause huge damage to the ozone layer, the layer that protects us from UV radiation, and if the ozone is gone, every complex organism will be gone as well.
