From David Brock, St Arnaud, Victoria, Australia
Your story on the high likelihood of alien civilisations experiencing a climate crisis akin to ours seems to presume that all intelligent life will be destructive 10 April, p 12. This is only true if life tends to follow the religious notion that a planet is a gift from god to use as it wishes. The view of many Aboriginal Australians, that we are responsible for the land, is better. This bestows nature with a god-like status.
I suspect an advanced alien civilisation could only exist long enough to conquer deep space by adopting that view. If aliens did visit us, I expect they would not be destructive invaders, but wise and respectful scientists.
