A/D: The most important problems in today’s world will be solved in our lifetime.
While there is still hunger, poverty and violence on earth, environmental degradation and population growth are considered as the most significant problems that needed to be solved as soon as possible. Although we human beings have struggling with these issues for centuries, unfortunately, the reality offers a depressing picture. Therefore, from my own perspective, I really doubt whether we have enough capacity to put an end to these in our lifetime.
First of all, the increasingly serious environment pollution cannot be solved thoroughly in the short term. As we know, since the Industrial Revolution, there is a tremendous increase in the use of fossil fuels, especially the coal, resulting in soil erosion, deforestation, acid rain, not to mention the carbon dioxide and methane in the atmosphere. Despite the measures we have taken, the situation is still out of control. An obvious example to illustrate this phenomenon is the popularity of automobiles, which has soared dramatically over the past 40 years, exacerbating the impacts of global warming. But the more environment-friendly vehicles, such as solar-powered cars, are still on the experimental stage. So only if the technology matures enough, people can effectively restrict the consumptions of those conventional fuels to reduce the pollutant.
Besides, environmental protection also requires a huge sum of money, which can only be sponsored by governments. Yet in the real world, both the developed and developing countries regard the prosperity of economy as their ultimate goal instead of protecting environment. Based on purpose, the paradox between the environment and economy development is too harsh for those greedy politicians to make decisions.
What’s more, another fierce problem that we can’t ignore is the swelling population. Statistically, there are now more than 7 billion of people sharing the world together, competing limited resources to survive, while a research shows that the capacity of earth could only support and sustain approximately 4 billion people. Thus, under such great pressures of overpopulation, it’s hard to meet the demand for everyone, so hunger, poverty, illiteracy as well as criminal seems to be inevitable. On the other hand, in many developed countries, like Germany and Japan, the negative growth of population, in turn, results in a shortage of labors, which directly do harm to the development of economy too. Hence, taking these two sides into consideration, we still don’t find an effective and appropriate way to keep balance.
Accordingly, it’s not exaggerate to claim that these two vital and extremely complicated problems couldn’t be solve in the coming future for the sake of various contradictions interacting with each other.
