A survey published this week says that air pollution may be helping to combat global warming by improving the way the plants absorb carbon dioxide.
The study, published in the journal "Nature" says that since the 60s, the level of air pollution caused an expansion of the capacity of plants to capture carbon dioxide.
Scientists suggest that there was a 10% increase in the amount of carbon dioxide that is captured by plants.
One of the common senses of science is that plants grow better in days of sunshine, but the new research says this is not necessarily true.
According to the study, forests and crops can also benefit from gray days, because the clouds and particles in the atmosphere to better diffuse the sunlight and spread the light that reaches more leaves.
This improves the process of photosynthesis, in which plants convert light and carbon dioxide into food.
'Global dimming'
The scientists analyzed the impact on plants of more gray skies and less light - phenomena observed in the world since the 1960s, with increasing pollution.
They believe that "global dimming" has been responsible for increasing the productivity of plants in 23.7% between 1960 and 1999.
The study highlights some of the paradoxes that arise when one tries to combat global warming.
Insofar as the world tries to reduce smoke and particulates in the air to benefit the health of the people, that make it necessary to further increase efforts to capture carbon dioxide as the plants absorb less carbon dioxide when the air is more pure.
"[The fight against global warming], the air is pure, and the contribution that the spread of radiation gives the environment will disappear," said the "Nature" the scientist Lina Mercado, of the Center for Ecology and Hydrology in Wallingford, in Great Britain. "We need to take that into account."
