You'll never get them all to organize effectively; far too much inter-species politics and interpersonal bad feelings.

We should be worried about the ants. They've got their own conflicts but they're more likely to set them aside. It would only take a faction of the total ant population, working together, to conquer the planet and enslave humanity again.

> All spiders on Earth weigh about 25 million tons. That's about 478 Titanics. The ship weighed about 52,000 tons.
