Thanks for saying that. I do not care about humanity or earth's future 100 years down the line leave alone 1000 years.
I think it is incredible arrogant to even assume that we can have any impact on future that distant. Most of our forefathers could not have imagined even a fraction of technological advancement we have achieved and compared to our children 500 years in future we are still pretty much uncivilized cavemans.
Cavemen should not bother about the earth, they should bother about themselves first.
