"The climate will always change" is one the most irrational and uninformed excuse you can use (to put it lightly).The climate will always change. Will be hot a century, cold a century and nothing you do with what mankind does will change that. It's hot this year, but we are getting more rain than I can remember. It's wonderful. Usually a very hot summer brews a very cold winter. Funny how that happens.
Climate change. If you really think anything we do will affect and control climate change, then there is no use arguing. The only thing we are doing with "Green" is producing extremely toxic products that don't decompose.
The idea that "it's just nature doing its thing, so let's do nothing" makes zero sense.
Just say it as it really is: you only care about the money, the next generation can just f off.
