Replace beef with chicken to save climate: Report
3 April 2015 5:47 AM IST
Even though vegan diet is the most climate-friendly, we can continue eating animal protein and still make a major contribution to the climate if we replace beef with poultry and eggs, and cut down on our consumption of milk and cheese, says new research.
The study by David Bryngelsson from Chalmers University of Technology in Sweden examined various future scenarios to determine how the climate would be impacted if humans were to change their diet.
"Cattle ranching is already responsible for 15 per cent of the greenhouse gas emissions that humans cause," observed Bryngelsson, who recently presented his doctoral thesis on land use, food related greenhouse gas emissions, and climate change.
He noted that increased consumption of beef runs counter to the goal of limiting the temperature increase to two degrees Celsius.
There might be ethical objections to the current chicken industry, but Bryngelsson believes that climate gains will prevail even with more animal-friendly production methods.
Technical improvements in the production chain can to a certain extent also reduce the food industry's climate impact, but cattle are still the biggest problem, he noted.
