Overpopulation is My Top Concern
Hello, honorable judges and deal schoolmates.Today my topic is “overpopulation is my top concern”.We may have deeply felt the inconvenience and diminished quality of life that overpopulation brings about.Overburdened public transportation especially on holidays is challenging our endurance，sky-rocketing housing price discourages us purchasers，people in a few developing countries suffer from starvation and malnutrition.These hot iues have drawn my attention and raised the idea of overpopulation to my top concern.Human is now beginning to overpopulate the earth and the expansion trend won’t be easily slowed down.Therefore many environmental problems arise，including rising levels of atmospheric carbon dioxide，global warming and pollution like air pollution，water pollution, soil contamination and noise pollution.Other side effects also emerge in succeion.For example, wars over resources and land increase;maes of species extinct;food ,water and foil fuels are running short;unemployment and crime rates rise dramatically and so on.Generally speaking, overpopulation can result from increased birth rates, together with a decline in mortality rates due to medical advancements.Furthermore, increases in life expectancy and resource availability also contribute to the rising population.In consequence, humans outgrow their available resources and the basic life would be streful in turn.So what joint efforts can we make faced with the situation? On one hand, birth control, like one-child policy which China has strictly implemented, would help to control and reduce population gradually.On the other hand, programs such as family planning education and putting women in workforce should be announced worldwide which I think will help avoid some unintended pregnancies.Moreover, humans are expected to build space habitats in the foreseeable future thanks to further space exploration.That’s all, thank you!
