I would be careful about blaming "human ignorance" because, case in point, a great many of us are aware of the climate crisis and feel the need to do something about it. In the US, for example, most of the component policies of the Green New Deal poll quite well across party lines.
The problem is that the climate crisis demands large-scale collective planning and decision making, and our systems for doing so have been completely co-opted by powerful economic entities. The actions available to the average citizen amount to putting aside everything in one's life to become an activist (which most people don't have the luxury to do), occasionally voting from a menu of pre-selected corporate-backed candidates, or making ultimately insignificant lifestyle changes (and even that has been subverted by economic powers through "eco-friendly" consumer products).
It's always helpful to look at a problem through the lens of power relationships before blaming "people" for being stupid or ignorant. Certainly some people are, but that doesn't mean it would solve the problem if they weren't.
