RE: Why environment matters: St Matthew Island comic (Director's commentary)
When you really think about it, it's like reindeers represent humans, with overpopulation that slowly depletes the resources, and may lead to our demise.
Yep. That is my motivation for drawing the comic.
The reindeer ran out of lichen. When I drew the comic, I thought that fossil fuels (especially oil) are humanity's equivalent resource that we are consuming.
I think that there are other candidates for resources that we are in the process of exhausting. Such as topsoil getting eroded into the oceans at an alarming rate.
We are also pushing the limits of the atmosphere's and ocean's abilities to absorb carbon dioxide, without disastrous effects (such as global warming, and ocean acidification).
If only we could maximize the capabilities of renewable energy and other alternatilve power sources, we could survive without burning fossil fuels. Then it could impact our environment greatly as it will mitigate the emission of toxic gases directly into the atmosphere.
