Columbia University, the University of Maryland, and the Smithsonian Institution are working on visual recognition software to help identify species from photographs. Leafsnap is the first in a series of electronic field guides being developed to demonstrate this new technology.
This free mobile app helps identify tree species from photographs of their leaves. Leafsnap currently includes the trees of the Northeast and will soon grow to cover the trees of the entire continental United States.

The realization of Leafsnap was possible thanks to the collaboration between Peter Belhumeur (Columbia University), David Jacobs (University of Maryland), and John Kress (Smithsonian Institution).

The high quality photographs on the website leafsnap.com and in the app were made by the the not-for-profit nature photography group Finding Species.

In Italy 30,000 people die every year because of air pollution caused by fine particulate matter (PM2.5) only – which corresponds to 7% of all deaths (excluding accidents). In terms of life expectancy this means that, on average, air pollution shortens the life of every Italian citizen by 10 months; 14 months for those living in Northern Italy; 6.6 months for those living in Central Italy and 5.7 for the inhabitants of Southern Italy and the islands of the country. Northern Italy is the most affected area. Respecting laws would save 11,000 lives every year.
