Human activities conclusion What’s the author’s purpose in writing the passage? To raise public awareness of environmental protection by pointing out the tiny possibility of our moving to Mars in the future. Why?

Humans have yet not visited Mars. People want to go to Mars on holiday. There are plants growing on Mars. The greatest to life on Earth used to be nuclear missiles. One day, humans will have to go and live on another planet. Our Plan A includes developing renewable energy resources. The Biosphere 2 experiment ended in failure. Since the 1960s, we have been sending unmanned spacecraft to Mars... space agencies of various countries are planning manned missions to Mars that could take place within the next 25 years.(Para3) In the 1960s and 1970s, the greatest fear was that the human race, and possibly all advanced life forms on the planet, could be wiped out by nuclear missiles.(Para1) Scientists are thinking of ways to lower this risk, such as replacing coal and oil with forms of renewable energy.(Para1) Although the two-year experiment was not a success, it did provide us with a better understanding of how humans might be able to live on another planet.(Para4) 1.Which is better, to solve Earth's problems or to live on Mars? Why? I think that it is better to try to solve Earth's problems. On the one hand, Earth is the place where life began, where life has lived for billions of years. On the other hand, it is easier and safer for us to protect and save our planet than to move to another distant planet.
