One third of air pollution in California is from China

"...researchers concluded that 208Pb isotopes are a marker for PM2.5 from eastern Asia."

The national and social policies to pollute remind me of Mao's famous quip about welcoming a global nuclear war to control his own population are regain greater China's rightful place in the world.
