We should increase our development of alternative fuels, taking advantage of renewable resources, like using corn and sugar to produce ethanol or soybeans to produce biodiesel.

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.

If we can produce more ethanol and bio-diesel to help fuel our vehicles, we will create jobs, boost local economies and produce cleaner burning fuels. This will keep dollars here at home where they can have a positive impact on our economy.

By reducing our dependence of foreign oil and increasing alternative energy sources such as ethanol, we can begin to bring down prices at the pumps, create thousands of new jobs and bring a much needed boost to our economy.

We can produce more per acre on a fifth of the fuel as the industrial food system.

We must commit ourselves to an 'all of the above' energy approach, with a major focus on increasing domestic production and expanding alternatives fuels, while increasing efficiency and conservation standards.

Because of technological limits, there is a certain amount of food that we can produce per acre. If we were to have intensive greenhouse agriculture, we could have much higher production.

There is also a marked global trend towards sustainable agriculture, building on traditional methods which use fewer chemical inputs, carefully manage soil and water resources, and work hand-in-hand with nature.
