As our civilization has entered the 21st century, we all more rely on better environment while also demand more output from nature. How can we keep such balance for longer, could this be a pure scientific question?

China has the most rapid growth rate in the world over the past two decades，indeed it has become the largest manufactory site on the planet. What many people haven't really realized is the problems of over farming, fertilizing, as well as over urbanizing. The consequences are that high-yield agricultural targets may have been reached repeatedly; however, natural environment has also paid high prices, maybe higher.

Earthwise, very little may we change now, yet we could see a new horizon of hope for a better vision in the near future by research and engineering.
