Initially some have good intentions to help and steward the environment but that is not usually what happens!
Wind farms are a perfect example. They are supposed to reduce carbon emissions but then they clear cut trees to anchor in the foundations for the wind turbines, they construct service roads to mountain ridges, they kills thousand of birds and bats each year.
Solar Farms are equally dumb. they consume thousands of acreage only to produce a small amount of energy and they also disrupt local plant and animal polulations and increase the temperature of the local area they are in.
Environmental planning is not easy however, I would trust native americans a lot more than I would someone from the green party!
