What is wrong with the Earth's atmosphere?

Answer 1

There are most likely multiple answers to this question. This is the global warming route. Many of the things on Earth produce CO2 and other greenhouse gasses (like cows producing methane or cars producing carbon monoxide!). And these gasses are lighter than air so naturally they travel upward to the higher parts of the atmosphere. This is where the sun's heat super heats these gasses and the heat is trapped in the atmosphere. This heats up the rest of the Earth, causing changes in weather patters, increased ocean surface temperatures, melting of glaciers and other bodies of ice in addition to others. There used to be a natural defense system to this, plants. But development is causing these natural defenses to be destroyed. So less of these gasses are being converted back into oxygen.

Answer 2

Some of the major issues with Earth's atmosphere include air pollution from human activities, the depletion of the ozone layer due to human-made chemicals, and the increase in greenhouse gases leading to global warming and climate change. These factors contribute to environmental problems like smog, acid rain, and changes in weather patterns.
