Tim DeChristopher single-handedly stopped some major BLM oil and gas leases from being sold by outbidding serious buyers. He admits he doesn't have any money but he wanted to stop the process and it is stopped until February. You can read about it here and here. He won bids on 10 parcels around Canyonlands and Arches.
He explains why he did it in his own words here. He's going to need a lot of support in the future for taking a huge risk to protect the lands we love.
I just love creative audacity.
