Amazon.com description: Product Description: Thrillcraft: The Environmental Consequences of Motorized Recreation exposes the lasting damage done to our land, water, and air from the growing plague of jet skis, quads, dirt bikes, dune buggies, snowmobiles, and other motorized recreational craft that are penetrating the last bastions of wild America. The increase in thrillcraft use is responsible for wildlife habitat fragmentation, disturbance of sensitive wildlife, soil erosion, spread of invasive weeds, loss of silence, as well as water and air pollution. With more than one hundred shocking color photographs, Thrillcraft vividly documents the destruction caused by these machines on American public lands. Essays by activists, policy experts, scientists, and others support the photographs, explain the harm done by these machines, and critique the cultural foundation of this phenomenon. Thrillcraft bears witness to the mindless destruction of our collective natural heritage and offers a vision for a future when the howl of the wind or wolf can again be heard more often than the howl of a machine.
