大学英语六级作文 Man Is to Survive

 Man Is to Survive
The human race is facing problems which are getting more acute as time goes on. The most serious are shortages of resources, environmental pollution, and the pressure of population growth. In turn, these problems cause poverty, disease and wars.
Pessimists say that the human race is facing extinction. This is because it is now too late to solve these problems, according to them. They predict that resources will become exhausted sooner or later, that pollution will eventually poison the planet, and that unchecked population growth will cause mass starvation.
But I do not agree that mankind is doomed. In the past, the human race has always shown that it has the wisdom to overcome any threat to its survival. In the future, too, mankind will survive by using its wisdom to find a way out of its problems.
