The National Oceanic Atmospheric Administration declared that the Caribbean Monk Seal (Monachus tropicalis) has gone extinct after not being observed since 1952.
For the last 5 years there has been futile attempts by the U.S. government at finding the seal species so now it is officially declared extinct. The last confirmed observation of the seals was of small colony at Serranilla Bank, in 1952. The reason for their extinction is, of course, us humans due to hunting for their meat and blubber.

Will we ever learn and take care of the environment? Think about how sad it would be if most of the species around us would become extinct. We are heading in that direction..
