I guess from a habitat perspective there are probably two things to bring up. One is that it's important to act now to protect habitats so that expanding the ethanol industry doesn't come at the expense of remnant wetlands and habitat.
On the feedstock side, early ethanol plants on the Canadian Prairies did use winter wheat as a preferred feedstock. More recently, spring wheat varieties have come along that have gained favour because farmers were more comfortable growing them, and winter wheat has kind of fallen by the wayside. So I think the time to act is now, as the industry is growing, rather than waiting until the industry has matured and then having to stop.
