because these fields are extremely attractive to weeds and pests. That is why using chemicals on the food we consume isn’t the healthiest option for us. In Pollan’s essay, Unhappy Meals he states, “The American food system has for a century devoted its energies and policies to increasing quantity and reducing price, not to improving quality.”(Pollan 13) This low-quality food being produced by industrial farming heavily impacts our health and that is why it shouldn't be about increasing quantity…

almost completely renewable and its energy output far exceeds the energy required to start and maintain the reaction has been a focus for many years. Energies that are present today that involve burning things to produce electricity, such as coal, produce tons of pollution at a worldwide level.

river water to turn turbines, or on a large scale with a hydroelectric dam. The dam straddles a river, blocking its progress downstream. Water collects on the upstream side of the dam, making a reservoir. The reservoir becomes battery like, storing energy that is released little by little. To let them know how much it would cost to begin drawing from the resource I would start off by telling them that it is very expensive but it'll be all worth it! Hydroelectricity is produced for an average…
