Ⅵ、One possible version:
With the global warming getting worse, more people choose to live a low-carbon life for the purpose of reducing greenhouse gases.
We'd better save much water and paper and electricity. We should use less carbon and oil.It's important to turn off the lights, and computers when leave rooⅢ、 We should take our own bags in shopping instead of using plastic bags from supermarket. We can buy few clothes which are unnecessary. We shouldn' t buy or use one-offcups or chopsticks or bowls. It's good for us to walk or take bikes to school instead of taking cars. We can also plant more trees to change air around us.
Let, s take action and be a low-carbon people !
