Mars making New Earth

Nowadays, science doesn't stand still and every day we have a lot of new discoveries. People have already defeated a large number of difficult diseases, robots have already changed some professions and now people are thinking about New Earth-Mars. What do you think about this idea? 

  In my mind, is a really good idea for our world and for our future, but I think that scientists will forget our planet. just look at our world, we have a lot of ecological problems and a lot of global problems like pollution. I guess that discovery a new Earth is a very responsible step for us, people should understand that is so difficult. In my opinion, scientists must have to figure out how to save our world from dying because it's very important for everybody. Of course, new Earth is a fantastic idea because we should develop our world and d everything for this and Mars is a good platform for experiments, but I think that first of all we should save our Earth. 

  Other people are sure that we shouldn't do it and we can forget about this statement "Mars making the new Earth". People guess that we don't have enough skills and life experiences. They think that our people and our world don't need it. In their opinion, Mars should be just a planet and people shouldn't interfere. Also, people think that Mars doesn't have enough important resources for discovering and it will be a bad experiment. 

  All in all, I think that people should develop our world, our planet and of course don't forget that boundary just in our head and we can do it everything. And I have a question, Why not to try to open new Earth?
