They won't and it would not affect our food chain. It would be a terrible loss to the planet though. Fortunately, they are not endangered and their numbers are still growing. They now number well over 20,000.
If a polar Bear Were to come Extinct then it would effect the Arctic food chain
Plankton are at the very very bottom of the food Chain. So, if they go extinct then whatever is the next up the food chain will become extinct and so on. If Plankton go extinct, life as we know it is over.
If the Northern leopard frog were to become extinct it would break the food chain. That would cause a collapse in the ecosystem.
polar bears are a huge part of the food chain in arctic regions and there would be an overpopulation of many animals.

It would effect the food chain and other marine life would become extinct
tigers and leopards eat orangutans
Each time an animal goes extinct a block of the food chain goes down and we need them to eat the seals so we wont have to much seals or to less bears, and if the food chain breaks we die cause we need them for food.Plus we want our children to see polar bears.
because if they become extinct, it could have a huge inpacked of the food chain..
Because if they do the whole chain reaction would happen
They will become extinct, upsetting the food chain. They are already endangered T^T
Cheetahs in Africa have not yet become extinct, but that may happen soon given habitat loss and poaching. There are prehistoric cheetahs that have been discovered in North America that went extinct relatively recently (in the last 25,000 years).
Kelp is intertwined in multiple food chains. If sea urchins go extinct, the other organism will feel in the gaps.
