Who is a greener consumer

Here is a piece of student’s work about who is a greener consumer and how to be green. Can you use the new expressions to improve this passage
Mr. Black and Mr. Brown are both 32 years old. Mr. Black is 75kg and Mr. Brown is 84kg. Their cars are AF626. Mr. Black uses 30 litres of petrol a week, while Mr. Brown uses 50 litres of petrol a week. They both use 2,000 litres water a week. Mr. Black throws away 4kg rubbish a week, but Mr. Brown throws away 9kg rubbish a week. So Mr. Black is a greener consumer.
I think using less water as well as petrol and making less rubbish are helpful for us to be green.

First, we know that water is valuable. Petrol is like water. It is a kind of valuable resources, so we have to save them. On the other hand, gases from petrol burning is the same as poisons to the atmosphere. Above all, using less water as well as petrol is helpful for us to be green.
