version
Since the climate will keep on warming for decades even centuries, is there anything we can do? The answer is for sure. As individuals we should do our part. We can make small changes like taking public transport to reduce greenhouse gas emission. In addition, we can choose to buy the recycled products, use environmentally friendly shopping bags, etc. As for the government, strict laws concerning global warming have to be put into effect. Besides, it’s better for the government to encourage people to find and use more renewable energy.
② Greenhouse effect--- greenhouse gases-- we need those gases.
