There are many threats to global food supplies. Explain the problem, identify possible solutions, and asss the implications of implementing the solutions.
The food curity is a potential crisis to the world in terms of food supplies and food safety while the global population is projected to reach 9 billion by 2050 (Black叙述文, 2010). This essay, first of all, will just focus on the threats to global food supplies from two main aspects: the threats caud by the objective factors in a broad n, and the challenges attributed to the subjective factors which cloly related to the human behavior. After the analysis of the problems, a number of feasible solutions will be suggested with the implications which will be further discusd accordingly.
Although population, conditions of technology and economy, and climate changes小兔子乖乖歌曲 em to be correlated with the human beings, they are both factors which cannot be changed by a simple policy or a short-term plan less than a decade. Therefore, in this essay, they are classified into the objective factors challenging the food supplies. As is commonly known, population booming will directly lead to the vere shortage of land and water which are es
ntial to the food production. Weak conditions in terms of technology and economy accelerate the ‘yield gap’ and aggravate the threat, making the poor area more vulnerable (Godfray, et al, 2010). Also, extreme weather along with the deterioration of global climate will damage the crops. Climate changes including global warming will change the asonal patterns of pollination for crops which would influence their production (Slaght, 2012).
On the other hand, human factors contain more complicated reasons which are different from nations and industries. Generally, veral main reasons can be concluded: mismanagement on ecosystems caus the dramatic decline in some species which eventually leads to the reduction of food supply(Slaght, 2012). Along with the regional industrialization, the exportations of fruit and vegetables to developed countries displace local staple crops, which indirectly impacts the undeveloped areas suffering further from the malnourishment (Slaght, 2012)演讲者英语. Besides, food waste during the transportation and processing, retail and home stages compris a large proportion both in developed and developing countries (Godfray, et al, 2010).
Solutions to the problems are numerous which cannot be elaborated in this essay, but two directions are very clear for us in facing the threats, which can be generally applied. The first one is controlling and reducing, that is controlling the population increa and reducing the food waste. For example, in China, One-Child policy is an effective measure which can be drawn on by other countries like India and Indonesia, facing the same population booming challenge. Although it is controversial from a religious and human-right perspective, we had to admit that special circumstances need special treatments. Similarly, food waste needs to be reduced before we tend to increa the food production. Better transport infrastructure, better-functioning market, post-harvest storage technologies, legislation etc. (Godfray, et al, 2010) all could be applied to saving the prent available food production. The other direction is improving and facilitating. Obviously, improving the food production through new technology will back up the long-term development of food supply. It is a long list showing the technological breakthroughs on agriculture science in recent years. Among tho, genetic techniques are substantially accelerating the yields of agriculture especially for the staple foods for poor communities
(IAASTD, as cited in Godfray, et al, 2010). Meanwhile, globalization offers the under developed countries or areas more opportunities to the global market and new technology to boost the yields. More communications in scientific rearch between nations and technologic aid from economic advanced countries became more accessible,海尔面试 and will fundamentally enhance the food supply ability of poor areas.
All the solutions are so encouraging for giving the world a prosperous future. However, it is crucial to keep a critical awareness that everything has two sides. Globalization that enhances the communication between nations and specifies the regional food production may be a double edge sword since the world market could be even further controlled by the developed countries which posss the first chance and the global view through advanced technology (Godfray, et al, 2010). F乖乖写作业urthermore, new technology including genetic techniques and chemical fertilizer might cau damaging side effects which are妇女节的英文 beyond our wildest imagination.
All in all, food supply threats from population explosion to climate change make the whole
world no way to escape, and human factors in various aspects worn the situation. Fortunately, solutions in different layers can be utilized. It should be always kept康有为是哪里人 in mind that the food supply shortage cannot be ttled by depending on using new technologies only. There is no fixed mode for any countries or areas to solve the problems rigidly, that is to say, different situations should be treated differently. Developed or undeveloped, profitable or environmental, short-term or long-term are the key words for the future solutions in tackling the food shortage. It can be anticipated that more sustainable food production and balanced food consumption are the future trends of food supply.
