Which of the following are biofuels? Select all that apply*
Sonbull [250]

Answer:

Biofuels have been around longer than cars have, but cheap gasoline and diesel have long kept them on the fringe. Spikes in oil prices, and now global efforts to stave off the worst effects of climate change, have lent new urgency to the search for clean, renewable fuels.

Our road travel, flights, and shipping account for nearly a quarter of the world's greenhouse gas emissions, and transportation today remains heavily dependent on fossil fuels. The idea behind biofuel is to replace traditional fuels with those made from plant material or other feedstocks that are renewable.

But the concept of using farmland to produce fuel instead of food comes with its own challenges, and solutions that rely on waste or other feedstocks haven't yet been able to compete on price and scale with conventional fuels. Global biofuel output needs to triple by 2030 in order to meet the International Energy Agency's targets for sustainable growth.

Name three desirable traits that are being transferred into genetically engineered food crops how might these traits helped incr
____ [38]
<span>The first desirable trait that is being engineered into our crops is sustainability. This means that crops are being bred to be able to grow in adverse conditions, ensuring the ability to sustain our food supply as humans. The second, are the alterations being genetically done to crops to eliminate the need for pesticides. By heightening the crops natural ability to eliminate and deter pests, there are higher yields and the elimination of pesticides seeping into and poisoning the human consumer. And, finally an ability to eliminate the need for traditional breeding in crops. By genetically replicating plants, we are eliminating the chance that the human race may "run out", of seeds, of starts, of the need for pollination. This basically ensures us an unlimited food supply, just in these three traits being bred into our crops.</span>
