of energy is used also in dealing with substantial flows of waste in the forms of packaging and discarded products.

We have harvested them using the low-hanging fruit principle, which means that further increments of extraction will entail rising costs (for example, the oil industrys costs for exploration and production have recently been soaring at nearly 11 percent per year ) as well as worsening. Nuclear boosters advocate new fuels (thorium) or technologies (fast breeder reactors) to address these concerns. As those inputs are removed from food systems, it will be necessary to bring growers and consumers closer together, and to replace petrochemical-based fertilizers, herbicides, and pesticides with agro-ecological farming methods that rely on crop rotation, intercropping, companion planting, mulching, composting, beneficial insects, and promotion.

For the Ryan Cabrera album, see.

We must shift to using natural, locally available building materials, and more labor-intensive construction methods, while dramatically reducing the rate of new construction. As mentioned earlier, we will need many more farmers, especially ones with extensive practical, local ecological knowledge. We always adapt our energy sources, as much as we can, to suit the ways we want to use energy. So far, we have seen energy declines primarily in times of severe economic recessionhardly ever purely as a result efficiency programs.
