Ozone pollution harms East Asian crops, costing $63 billion a year, scientists say

Fossil fuel emissions aren't just driving climate change and worsening air quality, they're also hurting crop yields enough to cause some $63 billion in annual losses in East Asia, scientists say. With high levels of ozone pollution, China, South Korea and Japan are seeing diminished yields in wheat, rice, and maize, according to a study published Monday in the journal Nature Food. China alone is losing a third of its potential wheat production and nearly a quarter of rice yields as ozone disrupts plant growth. That has worrying implications beyond the region, with Asia providing the majority of the world's…
