CO2 released by fossil-fuel burning will cause climate change that will contribute to extinctions of some species in the future. How does this affect decision-making? Group of answer choices Extinctions are generally not included in the economic models, so we should not do as much to reduce global warming as indicated by the models Extinctions are generally valued highly in the economic models already, so the optimal path from the economic models is the way to go Extinctions are generally given much more value in economic models than the species really have, so we should ignore the models and global warming Extinctions are generally not included in the economic models; if we wish to avoid extinctions, then we should do more now than the optimal path from the models Extinctions have nothing to do with the economy, and it is just silly to discuss extinctions and the economy together
