Only two-dimensional thinkers could possibly believe otherwise. The irony of the successful campaign to stop construction of nuclear power plants in the United States is that it has led to vastly increased use of coal, which tends to increase the amount of carbon dioxide in the atmosphere. But at the same time, the decrease in farm land because hard agricultural technology is so much more productive has meant a huge reforestation of America. Growing trees take carbon out of the atmosphere, so much so that North America is not, on balance, contributing to the worldwide increase. None of this is what Soft Greens would predict, and Huber's recurring theme is that grand theories of everything, applied coercively by planners who are certain they know better than anyone else how to save the planet, are likely to go disastrously wrong.
Soft prescriptions tend to be wrong on the small scale too.
The one thing there is a genuine scarcity of is unspoiled land, and hard technology conserves it. Huber's model of conservation is Theodore Roosevelt, not because he liked to shoot animals but because he recognized the importance of unspoiled land that would give the animals room to live and restore the human spirit as well. Hard, not Soft, is the path leading to that green vision.
