First of all, the problem of air pollution comes from human activities every day. Many human activities contribute to the problem of air pollution in the world; it is not just about human activity but actually climate change. Climate change has an impact on human activity, which is why people try to handle it. For example, humans build new buildings for their safety when the weather changes. Another example is expanding the land and cutting down the trees in the forest to continue their business. They expand the land for a new building to build a new company, which makes them manage their problem, but the impact of that is air pollution for human health. That is not good for poor air because the poor air comes from nature, such as trees.
