Canadian scientists said that the process of climate change on earth could cause mass extinction species such as a collapsed domino chain that the first is human unsustainable activities.
"We have seen birds, animals, insects, even plants migrate elsewhere," said ecologist Jeremy Kerr. "But many species do not migrate fast enough to avoid extinction."
"The predictions of a rapid extinction, mass seem to be true," Kerr said. Last year, the Millennium Millennium Biology (MA) project warned 30% of the Earth's organisms will disappear by 2050 if countries continue to emit greenhouse gases into the environment.
