A new study reveals that pizza and steak is to blame for worsening air pollution, as it is considered to put the environment at a new risk due to wood burning ovens and stoves in pizza houses including charcoal for steakhouses. These new findings are based on carbon emissions from Sao Paulo, Brazil.

This new study is carried out by a team of international scientists from several universities that is led by Prashant Kumar from the Department of Civil and Environmental Engineering at the University of Surrey, that is managed by the University Global Partnership Network.

These new results show how Sao Paulo is emitting unaccounted sources of air pollution, even if it is the only mega city in the whole world that uses cleaner bio fuel when it comes to private and public vehicles.

Kumar explains that despite Sao Paulo not contributing to the same high level of pollutants from vehicles originating from other mega cities worldwide, it is still crucial to examine some unaccounted for emission sources which include the wood burning of pizza shops that can reach to thousands and also domestic burning of waste.

Researchers reveal that there are apparently 7.5 hectares of eucalyptus trees in the Brazilian forests that are burned every month to supply wood for pizzerias and steak houses. This can amount to 307,000 tons of wood that is burned alone for pizza shops which is a significant number that now poses as a threat to the environment that can negate the positive effects of green biofuel use and policies on Brazil's vehicles.

Apart from this, scientists also note that there is also a considerable impact of this air pollution of the Amazon rainforest as this biomass burning is transported across the Atlantic coast.

This new study is published in the journal Atmospheric Environment.
