Humans are given earth and they polluted it, destroyed its environment in the name of development and now going after Mars or Venus...etc.
There may be some entities with good intentions in exploration but over a period of time, entities with evil intentions may join and story will be same like on earth, only timeline, tools, people, circumstances, places will be different.
Humans weren't 'given' earth - we evolved from the survivors of the last mass extinction event, alongside and in competition with everything else here. We have no more right to survival than a termite, say, but we have the same right to shape our landscape to suit our needs. Expansion beyond earth is a logical and necessary manifestation of the survival strategy our species employs: applied intelligence.
Enlightened self interest requires that we treat other forms of life on earth better, but only because that same applied intelligence shows us how connected our own survival is to theirs. Equally, that same self interest should encourage us to study and preserve indigenous life on other planets, since it may provide knowledge which assists our own survival on those planets.
Moreover, if sun dies, how Mars/Venus will help us? They are in our solar system. Is n't it?
So we need not worry. Moreover if death is natural process, then some alternative star may born by that time. As of now, Science may not be that much advanced to capture new star.
But that won't give a reason to destroy/pollute earth and move on. Can you guarantee it won't happen to Mars or Venus?
mars and venus are the first step. we aren't going to jump out of the solar system on our first try. we will be lucky if we don't have a lot of failures in that endeavor, even after the experience and materials we gain from the solar system.
>Moreover if death is natural process
humans are also a natural process.
>some alternative star may born by that time.
you mean a new star is going to come to our solar system before the sun dies? I think I must be misunderstanding. If not, that's asinine.
I don't really get how you can call it fearmongering. who is supposed to be afraid? most people only think as far ahead as two generations. the only people who are disturbed by your strange brand of environmentalism are people who think hundreds of years into the future, ie other environmentalists.
your billions figure is also a gross overestimate. our timeline is not so generous.
and don't forget that life took (actually) billions of years to evolve. what are you trying to protect on mars and venus that is more important than that?
