Why isn't it enough that fossil fuels are a finite resource? That alone provides good reason to reduce our dependence on them. The way I see it we have two options:
1. Do nothing until we can no longer extract the fuel we need to run our society. This will certainly lead to catastrophe. 2. Use the fuel we are extracting now to build infrastructure that will reduce our long term dependence on fossil fuels. This will ensure sustainability for future generations.
It's a no brainer and requires zero reference to climate change. So why isn't that enough?
