I would say "the extermination of the prairie dog pest" because if you eliminate one species from the ecosystem, then the ecosystem will be unstable.
Id say the best answer would be the Sahara. Sublimation is going from a solid to a gas. Imagine an ice cube, it would be so hot that it would go from ice to its gas form of water vapor, instead of melting into water. In the Amazon, it would most likely just melt. In the attic, it wouldn't change. And again, it would only melt in Florida. Hope this helps.

The issue that was created a source of contention and division for Muslims is who should have the right to leadership.
