There are a lot of threatened species, the India's tiger, the Africa's rhinoceros, the China's giant panda, the mediterranean's monk seal...and I think that the more important problem for the disappearance of this animals are hunters, that they gain a lot of money for this animals.
This year on holidays I discover that in my country have one threatened specie, is the river's crab and its problem for the disappearance are the american's crab because are a more heavy specie.
