Overnight, all higher life, multicellular life forms from trees and grass to dogs and elephants reached a level of intelligence similar to that of humans. For example, they can communicate effectively, using their own languages. How would events unfold on Earth? (just for the first few days, although longer timespans are welcome but optional)
Specifically, if animals were suddenly sentient and able to communicate, how might this effect an overthrow of the humans' socio-economic hegemony?
I'll add some clarifying details:
- Different groups of animals have developed to communicate in their own language families (dogs might have related languages and local dialects; cats would have their own languages and dialects).
- Also, they have been granted the level where they have translators & interpreters so that different groups of animals and plant life can communicate with each other.
- Animal interpreters can also communicate with humans.
(Although I'm excluding microorganisms such as bacteria and fungi for the purposes of this question, if possible, it'd be nice if answers also included what happened if they weren't excluded as well.)
