The Human Being

A Crowd Of PeopleIf you ever want to see the most deadly thing on the planet, just take a look in the mirror. We humans have already succeeded to start destroying the ozone layer, creating a weapon that has killed over 70,000 people already(The nuclear bomb), and are such a threat to animals that every year one percent of Earth’s animals die. In fact, between the years 1970 and 2005 the number of plants and animals has decreased by over a third because of habitat loss, overhunting, overfishing, pollution, and junk floating in the ocean- and all caused by us. So, like it or not, mankind is the most dangerous animal on our planet.
