All sectors must play bigger role in protection, analysts say

China still faces a host of challenges in its transition to a greener future, and the nation must enable greater social participation to bring all sectors of society on board in efforts to protect ecology and the environment, according to analysts.

Wan Jun, chief engineer at the Chinese Academy of Environmental Planning, said that to ensure its food security, China uses a substantial amount of pesticides and fertilizers to maintain its annual grain output, posing one of the main environmental threats in the coming decade.

"The pesticides and fertilizers China uses each year have exceeded the amount used by the United States and India combined, but there are no other options, as this is a 'must' to ensure China's food security," he said.
