The Part 1 question will be an essay on a given topic. A set of notes on the topic will be provided, and will include three bullet points. Candidates will be asked to select two of the bullet points and to base their essay on those two points . They should not attempt to discuss more than two of the points, as this will lead to the essay being less developed than required. Candidates will also be asked to explain which of the two points is more important in a given respect, and to give reasons for their opinion.
Candidates will be given three short opinions related to the bullet points. They may, if they wish, use these to help develop their essay, but they should do so in their own words, as far as possible .
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.
It is important to control the economic activities that are highly inefficient and are threatening the ecological balance on earth. Resources like forests, wildlife must be conserved at a sustainable rate by taking various approaches to save them. We must be far-sighted in our efforts for conservation and management and keep clear objectives and have mechanisms for action to get any real results. Specialized solutions may have to be devised to prevent the loss of species. Only setting aside areas of reserves may not suffice as a solution to conserving bio-diversity.
