Richie learned in his environmental science class that using biofuels instead of fossil fuels could decrease the amount of greenhouse gases released into the atmosphere
Richie wants to be carbon-neutral, so he decides to replace the oil furnace in his small house with a corn stove, which uses whole kernels of corn as fuel. Richie's friend Angela points out that Richie may have failed to take a certain fact into consideration when he decided to buy the corn stove. Specifically, Richie probably did not consider that ________. A) corn requires a good deal of energy to produce, and a wood pellet stove would have probably been a more carbon-neutral choice B) corn stoves have been shown to be dangerous because, unlike furnaces, they can leak carbon monoxide C) corn stoves are expensive, and Richie could have used the money to plant trees instead of buying the stove D) burning corn releases carbon dioxide, so there is no decrease in the amount of greenhouse gases being released
