求一篇英语作文，要求如下：“随着世界人口越来越密集（densely populated),空气污染已经成了严重的问题。空气污染主要来源于四个主要的人类活动领域：工业、能源业、交通运输业以及农业。经营工厂,为火车、飞机和公共汽车提供动力都需要能源。几乎所有这些能源都是通过燃烧燃料产生的,这就会造成空气污染。科学家们正在研究能减少环境破坏的新发电方式。增强的公共环保意识使诸如回收利用(recycling)等活动产生。”

Answer 1

With the improvement of our living standard, more and more people
can afford a car. As a result, our roads are more often than not crammed
with cars. However, with more and more waste gas being discharged by
the cars, the problem of air pollution becomes even more serious. So
nowadays we advocate to lead a low-carbon life.
My suggestion is we
should ride bikes more often instead of driving cars.By riding a bike,
we can not only exercise our body but also protect our environment.
