Global warming is the most important things that make lots of scientist are worrying about the future of the humans. So we need to act responsibly to reduce the damage that we do with our Earth.  I believe that the pollution and waste is one of the biggest threats to make the global warming. And most clearly expressed is from factories and exhaust fumes from vehicles. Moreover, population increasing also make a huge quantity of waste. The government can reduce air pollution by a lot of ways. First, they can introduce laws to put a limit on factories gas emissions or force companies to use renewable energy in production. Second, they can innovate the public transports system to make greener and convenient. By all these ways, government can reduce emissions. In fact, not just government have to do this, we have to act this too. We can reduce by use public transport like take busses and use metro. We need to actively participate in environmental protection activities. We have to put the trash to the rubbish, recycle plastic … Overall, both national governments and individuals must understand the harmful impact they have on the environment and be responsible to ease damage.
