We Must Continue Subsidizing Clean Energy to Save Our Crops
Currently, the world in which we live is slowly becoming the future graveyard for mankind. Around 230 years ago, the industrial revolution allowed humans to further specialize in the division of labor with the aid of advanced machinery. In today’s society, people adamantly rely on machines such as city busses, aircraft, and automobiles to make their lives easier and more productive. Unfortunately, many of these machines burn fossil fuels such as gas, oil, and coal to create enough energy to function. When these fossil fuels are burned, they release carbon emissions in the air, which ...view middle of the document...
Later in the article, Tubiello reports that irrigation-use efficiency could strongly decrease under future climate changes. The logic found behind this theory refers to the concept of evaporative demands linked to higher temperatures. After conducting a study about climate change with adaptation, Tubiello emphasizes that 75% more irrigation water was required to maintain current grain yields for maize and soybean due to the amount of water that was evaporating from increasing temperatures. Tubiello concludes that this is a costly figure because water is an expensive resource, and future climate changes have been correlated with long droughts. The extra and more expensive water needed to irrigate crops could have substantial economic repercussions for many farmers, especially in developing countries with dry climates. With less water, farmers will no longer be able to harvest as many crops as before, which is directly related to a decrease in crop outputs. Most importantly, this theory and potential outcome needs to be more heavily considered as a future reality by the American companies that pollute our air.
Another obstacle many American farmers now face due to climate change is the disappearance of quality pastureland. In a second article labeled “How Global Warming Will Hurt Crops” that was published by U.S. News, Kent Garber argues that future climate change due to global warming will hurt the supply of food. Similar to Tubiello, Garber also prefaces his opinion with an explanation of how a recent influx in carbon emissions is the driving force behind global warming and future climate changes. Shortly following his introduction, Garber further resonates with Tubiello by urging that rising temperatures are threatening many heat-sensible fruits and vegetables such as tomatoes. Rather than tying the threat to an increasing necessary amount of water for irrigation, Garber notes that at extreme temperatures, cells stop dividing and pollen dies. Garber also focuses on the increasing abundance of weeds in the southwest region of our country. These weeds were previously unable to survive in these areas due to cold temperatures. Resulting from an increase in temperatures, Garber reveals that high-quality pastureland is disappearing and farmland faces competitors for space. Furthermore, this evidence proves that the effects of climate change are already changing our ecosystems. This is an important concept because it reveals that if large companies continue to burn the same amount of fossil fuels, the damages to our agricultural systems will continue to increase exponentially.
Finally, a third threat that climate change will present to our agricultural system is the fact that increasing temperatures are correlated with higher incidences of insect reproduction and disease. In an third article labeled “The Agricultural Implications of Global Climate Change” that was written by Bradley Martin, Martin also gravitates toward the common belief that...
