“Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us.” ― Al Gore, An Inconvenient Truth: The Planetary Emergency of Global Warming and What We Can Do About It. What Al Gore said is true, climate change is caused by us, humans. It is what we, humans, have done, are doing and intend to do that caused and is causing global warming, therefore, man is to be held accountable for the changing climate.
