Great animation from the California Academy of Sciences about Introduced or exotic species, how and when they become also invasive, and the problems … Sourced through Scoop.it from: www.youtube.com
GR: This is one of three excellent presentations. I highly recommend them to anyone who wishes to learn more or teach more about these critical subjects. I once believed that invasive species would wreck Earth’s ecosystems before global warming became a serious force. The effects of global warming are coming faster than expected, however, and I now believe that stopping our CO2 emissions is our number one priority, a little ahead of reducing our population, preventing invasive species introductions, and so forth.
