Eric, how do you explain the record breaking profits of the oil industry
during Katrina and now? They earn $75,000 per minute in profits. How do
you explain it?
Also, even if the sun is responsible for the planet's warming, which there
is no way to know is the case, why do you think people (presumably
including you) are so against cleaning up the air and water? Do you think
that if cars got more energy efficient, people would use less oil and the
oil industry would be in danger of making less money? Something along
those lines?
