Give reasons for your answer and include any relevant examples from your own knowledge or experience.
Essay:
The possibility of a global food shortage is looming and the effects could be felt in the near future. Although all kinds of advances made in agriculture from using fertilizers to mechanization have increased food production, many people around the world still go hungry. The causes of this global dilemma are well-known and the solutions might be found in human will in a new age of science and technology that have the potential to transform agriculture and food production.
A combination of five main factors contribute to the problem of food shortages as seen in some regions on the planet. The first factor is poverty trap since people in need simply do not have enough money to purchase the food they need, even if the supply may be available. The second factor is constant disruptions of people’s lives such as armed conflicts, prolonged droughts or severe floods. The third factor is the global warming that causes the climate to change, resulting in seasons of bad harvests. The fourth factor is the uncontrolled population growth, which means there will be many more human beings to be fed. The fifth factor is food wastage because it is estimated that one third of food produced is never consumed, which represents a missed opportunity to improve global food security in a world where one in eight is hungry.
Are there effective solutions to the food crisis? The good news is that innovation in agriculture is coming to rescue. Up-to-date information science and technology, improved communication systems, robotics, drones and other new inventions have the likelihood to boost agricultural yields and reduce food wastage while tempering environmental degradation. As an example, for the past dozen years or so, farmers have used tractors equipped with GPS and computers to collect data on how much amounts of fertilizer, water, and seeds are delivered where. The next generation of devices and systems include robots that can move along rows of crops and identify where inputs are necessary while drones can gather similar information through high-resolution visual imagery.
In conclusion, there is no deficit in scientific and technological methodology, but there is a deficit in human will to solve the problem of food shortages. In view of the fact that millions and millions of people who are still hungry, effective actions should be taken in innovating science and technology. Otherwise, the global food problem is likely coming sooner than is expected.
