What are the endangered animals in your country?

As the world gets globalized, exotic species come to our nature more often without obvious notice. Nobody seems to know exactly how the exotic species were introduced. Some threw strange species away into the river or forest, others purposely put those into our nature, and still, others unpurposely brought those attached to their personal items. What problems occur, exotic species start to break our natural order. For example, first, bass which is fish from is breaking stream order. It eats up our native fish in streams or rivers, and the number of bass increases. Second, our native species, frogs were eaten up by American bullfrogs which is much bigger than native frogs. To solve this problem, we are allowed to fish bass as much as.
