A report proposes that the US spend $100 billion (over a period of many years) to prevent extinction of hundreds or thousands of endangered species.

The proposal does not include curbing global heating, but it depends on doing that. Without that, preventing a mass extinction is hopeless. In addition, without curbing global heating, technological society is likely to take such a big hit that it will no longer have the capacity to do the things proposed in this plan.

We must do both.
