Well the current problematic situation of animals is relatively well contained to the Western sphere (US, EU, maybe China).
The Chinese already recognize the effects on nature, the EU too (and iirc they're already beginning to introduce measures), the biggest problem is and always will be the US because of the huge influence of the farming lobby on US politics (and even if that was not the case, then the grid-lock between D/R where everyone boycotts bills from the other side, just because. Brain-dead US politics.)
