I think humans are the best thing to ever happen to this planet, it's kind of bland and boring without overarching social constructs and civilization 
It's only regrettable that it was the only species to achieve this level of sapience by this time... I mean, elephants aren't really that far off, and dolphins and octopi are just a few reasons short of taming the oceans... hell, even your closest primate cousins could very well be where you are in perhaps fewer than 50 million years.
Global warming... who cares?
By the time it's really getting nasty, you'll be off this rock, and spreading through space like a slow plague

Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day
