We have the technology to fly farther than ever before under our own power. With focus and determination, we can realize tremendous gains in efficiency through the development of ornithopters which precisely imitate specific types of birds such as Ardea herodias. This can be part of the way forward for us as a species as we approach E.O. Wilson's 'bottleneck'. The twin concerns of peak oil and climate change demand that we act boldly to change our own future.
What could be more bold than engineering our way into the air in droves?
