Trade of animals (extinction)
Present
In the present day today we are facing our sixth wave of distinction. Unlike like the other mass waves of extinction this one, in particular, was done by us.
"In fact, 99 percent of currently threatened species are at risk from human activities, primarily those driving habitat loss, the introduction of exotic species, and global warming."
Future
"It could be a scary future indeed, with as many as 30 to 50 percent of all species possibly heading toward extinction by mid-century"
If not put to a stop now extinction will just get worse and worse. The more that extinction increases the less biodiversity we will have. -risk of extinction
"At the current rate of species discovery, the authors calculated, it could take hundreds of years to describe them all. Long before then--within a century--75 percent will be extinct."
"biodiversity loss is increasing, not slowing down," says IUCN director-general Achim Steiner
"Life on the planet seems to be returning to the days of the single supercontinent Pangaea 250 million years ago: globalization, as it turns out, is as much a biological as an economic phenomenon."

Past
Christopher Columbus brought animals and bugs with him to the new world and vice versa when he came back.
Research have concluded that the number of species going extinct since columbus's voyage have increased drastically.
Arriving in the Americas Christopher Columbus impacted the natural harmony of his surroundings.
"The main cause, as ever, is people, as humanity impacts the world's fauna and flora both directly and indirectly"
