Air pollution is much worse than you think
Air pollution is usually framed as a problem that affects the respiratory health of humans, according to co-author Tim Tear, but it has far-reaching consequences. All of that excess nitrogen, acid, mercury and ground-level ozone wreak havoc as they enter our soils and waters also. Ozone reduces forest and crop production, excess nitrogen harms waterways and fish stocks and acid rain makes lakes and streams uninhabitable by fish in the mountains.
The answer? Better regulation and better monitoring of air pollution.
