Who is a greener consumer
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 uses 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.
Read the article below to describe who the greener consumer is and summarize the similarities and differences, and then write a short passage to make a comment.
