The breeding and broad cultivation of semi-dwarf crop varieties in the 1960s and 1970s dramatically increased the grain production in the world, particularly in Asian countries, which was popularly recognized as the First Green Revolution. Many factors have shown that the first green revolution has brought some environmental problems as well.

To guaranty both the food security and environmental safety, the actions that China should take during the second green revolution were discussed.
