Experts tie the problem to the rapid urban development, and cutting down trees is another reason which is largely due to human activities. Some people do not pay enough attention to smog, and they don’t know it is partly caused by the gases from heavy industry and vehicles. These harmful gases also lead to acid rain, though a very small part of acid rain comes from volcanoes or wildfires. When these gases enter the air, they also lead to global warming.
