这篇文章基本完成了试题规定的任务，提及了低碳生活的重要性和一些具体措施。但存在一些语言错误和标点符号使用不当，影响了流畅度。

**语法和标点错误修改如下：**

1. 将“environmental problem”改为“environmental problems”以匹配复数形式。
2. 分句之间应使用句号或分号，而不是逗号。例如，将“living a low carbon life , thus”改为“Living a low carbon life, therefore,”。
3. “to begin with”应该是一个新句子的开头，因此应大写并且用句号或分号将前一句分开。
4. “in addition to,”应改为“In addition,”。
5. “how to adopt a low carbon lifestyle”应单独成句，并改为“Regarding how to adopt a low carbon lifestyle, we should start with ourselves.”
6. “whenever we go out , we’d better walk or ride a bike instead of by car”应改为“Whenever we go out, it is better to walk or ride a bike instead of driving.”
7. “we can use cloth bags rather than plastic ones”前需要连词，比如用“And”来连接上下文。
8. 在“I firmly believe that if everyone makes great efforts to do so , we will surely see greener planet”中，greener前面加上冠词“a”为“a greener planet”。

改后段落：

As the global economy is growing at a rapid pace, environmental problems have aroused wide public concern. Living a low carbon life, therefore, has gained great popularity among people around the world. It is wise for college students to realize the significance of a low carbon life. To begin with, leading a low carbon life is crucial to protecting the environment. For instance, if citizens choose to take public transportation, carbon dioxide emissions in cities will be greatly reduced. In addition, living in a low carbon way can help save limited natural resources and energy, such as petroleum and natural gas. Regarding how to adopt a low carbon lifestyle, we should start with ourselves. Whenever we go out, it is better to walk or ride a bike instead of driving. And we can use cloth bags rather than plastic ones. I firmly believe that if everyone makes great efforts to do so, we will surely see a greener planet.
