Essay about environmental protection and conservation

In addition, other elements conspire to take away from the harvest for which we worked so hard to produce. Despite the best application of modern agricultural practices, an unavoidable portion of what is grown rots in the fields prior to harvest time, or in the world’s storage bins afterwards. Every year, depending upon geographic location and intensity of El Niño events, crops suffer from too little water and wither on the spot, or are lost to severe flooding, hailstorms, tornados, earthquakes, hurricanes, cyclones, fires, and other destructive events of nature. Many of these phenomena are at best difficult to predict, and at worst are impossible to react to in time to prevent the losses associated with them. In sub-Saharan Africa, locusts remain an ever-present threat (42), and can devastate vast areas of farmland in a matter of days. Even after a bumper crop is realized, problems associated with processing and storage lessen the actual tonnage that is available to the consumer. A large portion of the harvest, regardless of the kind of plant or grain, is despoiled or a portion consumed by a variety of opportunistic life forms (., fungi, bacteria, insects, rodents) after being stored. While it is conceded that at present the abundance of cash crops is more than sufficient to meet the nutritional needs of the world’s human population, delivering them to world markets is driven largely by economics, not biological need. Thus, the poorest people – some billion – are forced to live in a constant state of starvation (43), with many thousands of deaths per year attributable to this wholly preventable predicament (44). Locating vertical farms near these human “hot spots” would greatly alleviate this problem.

And of course it is the . demand for drugs that fuels Mexican drug smuggling in the first place. Take, for example, the current heroin epidemic in the United States. It originated in the over–prescription of medical opiates to treat pain. The subsequent efforts to reduce the over–prescription of painkillers led those Americans who became dependent on them to resort to illegal heroin. That in turn stimulated a vast expansion of poppy cultivation in Mexico, particularly in Guerrero. In 2015, Mexico’s opium poppy cultivation reached perhaps 28,000 hectares, enough to distill about 70 tons of heroin (which is even more than the 24–50 tons estimated to be necessary to meet the . demand).
