Should we.......
1. Focus on cleansing Earth from pollution and reducing waste
2. Or...focus on finding another Earth-like planet somewhere in space
In my opinion, as Earth will perish someday, either millions of years in the future because of the Sun, or next week because of a meteor, we should search for another planet where the next generations can live safe and sound. How about you?
I agree that we should endeavour to make humans interplanetary, for the eventual and unavoidable end of earth. However, we must conserve and protect what we have in parallel to this tremendous mission. Not everyone (animals included) will ever get the chance to see this future or get to go on the expensive escape ships one day. We must continue to make life on earth a healthy and safe one for all to enjoy, it is after all our home.
