If an apex predator (tigers) is removed from a habitat then the plant eating animals will populate too much.
Wolves in yellowstone when wolves in yellowstone were taken away the elk started to over graze on the willow and that was affecting the beavers, so the beavers started dieing off. Since the tiger is an apex predator in many ecosystems it would be a catastrophe if they go extinct, unlike lions the tiger lives in the (jungle, rainforest, savanna, etc.)Since the tiger is at the top of the food chain for most ecosystems it is a primary apex predator and will have the most effect if extinct. Unlike the lions who only roam one or two ecosystems will have very little effect on the ecosystem. According to HUFFINGTON POST they sold over 6,000 animal killing licences, this gave people the power to kill innocent animals with no penalty for
it. Because of poaching we are putting animals on a 24/7 watch in the savannah so that we could monitor their growth and decline in wildlife reserves. Then we also keep them in wildlife preserve so we could make sure that they all are healthy in every way possible.
Also some poachers are killing just for the heck of it, but also threatening to kill endangered animals for their own good of the sport, they just take what they need and leave the rest.
We are surrounded by endangered species. Majestic tigers and stuffed toy pandas are examples. We can also watch the elaborate courtship rituals of cranes and the strategic hunting habits of leopards.
