It is argued that some people have belief about the future that the problems in this planet’s environment will make living unable. So for survive , human beings nedd to find another one where people can live. In my point of view I totally disagree with the suggestion, because it is very expensive and almost impossible for all the people to move to another planet even if it can found.
The idea will be very much expensive. The scientists need to find another planet which if extreamly costly and also time consumed because for this kind of seach scientists need to invest a lot of money by sending satelight. No scientists are able to find this kind of planet like earth yet. For example, it is said that people can can live on moon because there is water. But travel to moon is so costly.
Finding the new planet for survival is still not happen. So , if it is found, all people cannot go there to live, it will definitly take long time for the availablity the chances for all to move in the other planet, because very few people has gone to moon to stay there for a long . if it is possible near future then also very few people can go there for experiment. After that if they are successful they some other can try for survive there. It seems to me that very much lucky or highly rich people can only try for this. For surviving people also need some other things . These all arrangments are not very easy to fix. For example, if moon is suitable for the survival , then scientists and highly wealthy person can go there. They need the other survival materials, food, medical facilities and others are also difficult to arrange.
To summerise, it may some people think of finding another planet for survival because of environmental problems in the earth. But this idea will be difficult to accomplish because of high cost and take a huge time for all people to live there as nno planet is found yet. So I am completely disagree with the suggestion, better we can work out on the environmental problems to fix it for survival
