Hmmmm...could be. Guess I should rethink my doubts and replace my Ford SportTrac with a PUMA.
Don't be so rash. First of all we do not know what the optimum earth temperature is. And since dinosaurs existed at a time prior to the emergence of the evil homosapien species, the optimum temperature could be much higher.
Now in order to reach this higher optimum temperature, I suggest that humans greatly increase our consumption legumes, dairy products, and dark beer. In order to do this on a large enough scale to be effective, a global governing body would have to be established for the establishment of dietary guidelines as well as their monitoring and enforcement.
The only thing we are currently lacking to promote this is somebody willing to bastardize their PHD for money and a really catch anacronym. But it must be done now! The world is depending on us. And if we are unsuccessful we will all die, ( But if we are successful, we will still die, but hopefully a whole lot richer.) ;)
