答案：Last Friday, we held a class meeting to debate about life on the Earth and life on Mars.
Life on the Earth is polluted and crowded, but we have enough water and oxygen. We can enjoy various tasty foods, and gravity is not a problem for us.
As for life on Mars, it would be clean with lots of space. However, nobody knows whether there would be water or oxygen there. Food would be in the form of pills, and its gravity is about three-eighths of that on the Earth.
In my opinion, life on the Earth is better now because it is more comfortable and we have all we need.
