Did we cause it? Not enough data. Did we contribute? Certainly. Can we find market solutions and encourage environmental entrepreneurship? Yes, and we need to. You want solutions? Start with efficiency. Government research rather than the strangulation of markets. Of course our government doesn’t actually want solutions. They want price fixing and control of essential commodities creating oligarchies. Then they want to kill competition by introducing unreasonable environmental regulations. That’s why 60% of California’s industrial base fled and the poverty rate is 23%.
