If you're going to change the food system, there is a lot that you, the consumer, can do on your own; but in the end, it will be very important to make changes at the national level.

There's been progress toward seeing that nature and culture are not opposing terms, and that wilderness is not the only kind of landscape for environmentalists to concern themselves with.

Much more has to be done to democratize the food movement. One of the reasons that healthy food is more expensive than unhealthy food is that the government supports unhealthy food and does very little to support healthy food, whether you mean organic or grass-fed or whatever.
