Gforce Gforce Posted over 2 years ago Population growth is a challenge or opportunity? What's your viewpoint from your country perspective as well as global ? Why you think so ? The challenge of population growth is how to keep resource usage, pollution, and CO2 emissions under control and how to adapt living standards in countries to each other in such a way that humanity can keep living the way they do now. Nowadays there is already overpopulation when taking resource usage, pollution, and CO2 emission in account. I mean if we all live like Americans we would need at least four earths to have enough resources for everyone. So we need to adapt our living standards and use Technological innovations to decrease resource usage. This is the real challenge of population growth. But I think walter radtke is assuming that it is possible to have 1000 times more people then we have now when technological innovation like green energy is very far developed? In the current world this would not be possible, the 2 billion people living a western living style are already more then is good for the earth.
