We Are The Biggest Environmental Threats

EY writes:*

What is the biggest environment threat? Pollution, deforestation, loss of biodiversity, or climate change? All I mentioned above are caused by the growth of human population. From “Tragedy of commons”, Hardin claims that the growth of human population brought up the demand of scared natural resource. India and China will be the examples in this blog. Both countries bear a great proportion of the world population; they both have different attitude to population growth. The one-child policy, which is the population control policy from China government, successfully delayed the world population from hitting seven million for four years. Although India was the first country that adopted policy for population control, it failed due to value the male child and bureaucracy. Because of the massive population, both countries need to input more and more food every year. From the throughout model, economy is a machine which withdraw resource and discard wastes as pollution. When the world population increases, the economy will produce more waste, and the scared resource will decrease over time.

We can use fishery industry as an example. If over-fishing happened which is too many fishing that fish cannot sustain their population by itself, the ecology system will be break and cause more environmental problems. In lecture, instructor discussed a few successful ways to control population. I believe that cost of living will be the best ways to achieve the goal. Given the assumption of everyone is selfish, if the cost of have a child is too high, people will give up having a child instead to have a well living standard.

Bottom Line: The world population should be the primary concern for humanity.
