Over five hundred thousand Rohingya have fled to neighboring Bangladesh, a country already overpopulated and struggling to meet the needs of hundreds of thousands of refugees.
But the government says the elephants are overpopulated in Zimbabwe, destructive to the ecosystem and potentially deadly to people when they're driven to human settlements in search of food and water.
Oftentimes, many people get driven and they get excited to see a new species, they see new fish, and it's very hard to pull away, like adding another fish or two, and by then you're overpopulating your fish.
