18. ## A new thought !

Dear Sir, I agree that currently all Research are not in this direction and rather in Specializing at How to compete with each other, how to make better weapns to Kill and Destroy etc which are a Waste of Time against the Enemy Environment and extra-terrestrial attacks ! We need to think as a Global Human Community before embarking on my suggested venture ! I also agree with your statement that right now this appears impossible ! Dear Sir, I agree with you 100 %
19. ## A new thought !

All the Research and Aim of Human Beings are to evolve into a Long-living and Long-lasting Species all the time looking to migrate to a Safer, more suited and Long-lasting Planet !
