Brazilian Beef: Greater Impact on the Environment Than We Realize

http://www.sciencedaily.com/

ScienceDaily (Mar. 7, 2011) — Increased export of Brazilian beef indirectly leads to deforestation in the Amazon. New research from Chalmers and SIK in Sweden that was recently published in Environmental Science & Technology shows that impact on the climate is much greater than current estimates indicate. The researchers are now demanding that indirect effect on land be included when determining a product's carbon footprint.

"If this aspect is not taken into consideration, there is a risk of the wrong signals being sent to policy makers and consumers, and we become guilty of underestimating the impact Brazilian beef has on the climate," says Sverker Molander, Professor Environmental Systems Analysis and one of the researchers responsible for the article.

In Brazil, beef production is the major cause of deforestation in the Amazon. The consequence is not only that valuable rainforest disappears -- deforestation also adds to the greenhouse effect. When the carbon-rich forest is burned down to clear land for farming, large amounts of carbon dioxide are released. An estimated 60-70 per cent of the deforested land is used for cattle ranching.
