Preamble
Before we go any further, there are some things you need to know. I am a philosopher at heart, and enjoy wondering about abstract concepts and ideas to the point where they become real scenarios in my head. The idea for writing this came shortly after I've finished readings Orson Scott Card's Chil... |

Global warming effects have been linked to a wide series of disturbing facts, like environmental degradation and unwanted changes applied to wildlife species.
It may not come as a surprise that climate change triggers weird, destructive natural phenomena, while making most of the animals shrink.
However, to compl... |

Researchers established that animal and plant populations in areas of the world most likely to be affected by climate change in the very near future will have to adapt to their new environment at the same speed. If this is not an option, then they will have to abandon their territories just as fast.
