I think life on mars will be possible one day in the future through the advanced facilities provided by technology

No, I don't. I think life on Mars is impossible.

The topic is very interesting and actual. It was nice to hear this conversation.

Task 1 answers said that: "Earth has less carbon dioxide".
But we can see in the text: "Student 2: Mars doesn't really have air, not compared with Earth. It's got about one per cent as much air as Earth.
Student 1: Right, and it's mostly carbon dioxide."
It means that at least 50% of Mars atmosphere consists of CO2. Let's even take 10%. And, according to the text, we can esteem: this CO2 volume is 0,1% of Earth air, whereas CO2 on Earth takes only 0,04% of total Earth air volume.
Therefore we can accurately say, that Earth has MORE carbon dioxide.

IMHO this question is generally incorrect

Hello danunahoi

You are right, that question is a bit confusing and perhaps even wrong. I've reworded that part of the exercise so that it's clearer now.

I'm very sorry for the confusion. Thanks very much for taking the time to help us improve this page!

All the best

i think human have the way to live in Mars but The environment on Mars is not suitable for humans. I think it would be great if humans could make the trip to Mars for everyone.

although living in mars is very interesting ; living human in mars for long time is very bad effect in our body .
we must think about gravity the mars ; because the human body made for living in earth and if we live in mars we get sick suck as less the body bones
then we could't grow our children in mars.

if it was possible to live in mars, i think that people will be already there

Maybe, while the population on our planet is increasing rapidly, natural resources on earth is decreasing. But similarly the technology and scientific resources are developing fastly. Now scienists have sent steliates to make new researches. Perhaps it is not possible for people to live in mars in near future,but most probably our grandchildren would be living in there.

yes , I think because technology grow more day by day and make new things for comfort life and unfortunately the earth getting hot day by day and living here getting hard so we need find place for living . I think one day human can live on Mars.
