Tropical forests are fertilized by air pollution: ""Air pollution is fertilizing tropical forests with one of the most important nutrients for growth," said S. Joseph Wright, staff scientist at the Smithsonian Tropical Research Institute in Panama.
"We compared nitrogen in leaves from dried specimens collected in 1968 with nitrogen in samples of new leaves collected in 2007. Leaf nitrogen concentration and the proportion of heavy to light nitrogen isotopes increased in the last 40 years, just as they did in another experiment when we applied fertilizer to the forest floor."
