I think pipelines are generally good news for America.
First, they are less expensive. This is how producers choose to ship, when they are allowed to do so. (Freedom is a good thing.)
Secondly, they are an environmentally safer way to ship oil and gas. I care about the environment, even if “environmentalists” do not.
Third, oil and gas production provide several layers of economic benefit for the US and the world. There is no point producing oil and gas unless you can distribute it. By the way, I look forward to Trump providing the green light to exporting liquid natural gas oversees. They need the gas and we need the money.
Fourth, the only certain environmental effect of increased carbon dioxide in the air is that trees and other plants will breath more easily. More plant life means more animal life. More species will be protected.
Somebody made a recent emotional appeal yesterday on facebook with pictures of national monuments and parks stating that “would you like a pipeline covering this ground? I am wondering, isn’t that wrong? Aren’t the pipelines underground? Wouldn’t it take an earthquake to break one?
I am not entirely sure about plants, I think that even plants have limits of efficiency, although that is certainly a higher concentration than what we generally get from the air we breathe.
