I won't argue that we should not invest in curing cancer but with money at stake in big pharma the incentive are already high and investement is probably higher than climate change already but I didn't search a source to confirm that.
The truth is that curing cancer might save some more humans but what about all animals and plants we will let die if we continue to destroy our environnement like we do today. Earth will not burn into flame but living comfort will degrade for future generations of humans staying alive and all other living species that share our planet with us.
