The Egyptian study is especially timely, as we may be currently on the brink of another own ecological collapse. And this time the catastrophe may be on a global scale. There have been many warning signs that the planet is in trouble over the last few years. Rising temperatures, melting ice-caps, the increase in extreme weather events and ocean acidification all point to man-made climate change.
We have seen animal species suffer from climate change as well. The adverse knock-on effects of global warming on polar bears have been widely reported. But now other animals under threat include the Antarctic’s Adélie penguins and North Atlantic cod. The Central American golden toad has already become extinct, a victim of climate change in its habitat – cloud forests.
