In evaluating options such as emission 
abatement plans that would reduce livestock greenhouse gases by 
providing different food sources for the animals and using manure for 
fuel, scientists have found that these methods provide minimal benefit 
and in fact could create larger problems of both food quality and 
ethics. 
Moreover, a decade-long study by New Zealand’s 
AgResearch concluded that such alternatives only reduce emissions by a 
few percent. Moreover, UK Food Ethics Council Executive Director Tom 
MacMillan has raised similar concerns, emphasizing the importance of 
reducing meat and dairy consumption to significantly minimize livestock 
emissions. 
Mr. West, Mr. MacMillan, New Zealand AgResearch and 
UK Food Ethics Council, many thanks for your insightful findings. We 
look forward to people everywhere supporting the environment through the
 ultimately sustainable plant-based fare.
