We can thank "big oil" for advancing civilization such that we are not living a third world country by our current standards.
Oil has been very important, but not Big Oil, and oil, like everything else, is double-edged sword. We might run our economy on it, but you can't drink it, and you can't drink the water it's polluted.
Big Oil is here and my water is clean. People in third world countries have much more trouble obtaining clean water than I do. Thank you "big oil"!
It's clean now.
That pipeline is going to go over the Ogallala Aquifer. Which is the water source for several states. States that grow much of the food we eat. It's not called "The Bread Basket" for no reason.
When that pipeline leaks, it's not a matter of IF, it's a matter of WHEN, it will destroy that aquifer. Which means people in several states won't have water and farmers in those states will go out of business. America will see shortages in certain food and the price of food will skyrocket.
People die without water and food.
That tar sand isn't staying in America. So it's no benefit to America.
Lastly, I have serious problems with a private company from a foreign nation stealing American's land for that pipeline. The eminent domain clause in the constitution isn't meant for private foreign companies to steal land from Americans.
