Regulations
 designed to improve public health and reduce smog by reducing air 
pollution from trucks burning diesel fuel in the US state of California 
have been found to have an additional side benefit.
Over the past
 two decades, these measures also resulted in a 50% reduction in black 
carbon, a potent climate change agent generated from diesel fuel 
combustion and agricultural or other biomass burning. As a result, 
organizations like the Arctic Council and the Climate Institute have 
been focusing on the further reduction of this substance to bring about 
more rapid planetary cooling. 
Scientists and policy makers in 
the past have been concerned that reducing black carbon would also 
diminish other aerosols, whose presence has actually been attributed to a
 cooling effect. However, in this California study, Dr. Veerabhadran 
Ramanathan of Scripps Institution of Oceanography calculated that the 
reduction of black carbon resulted in a significant cooling effects for 
both the region's heat and water supplies. 
Moreover, according 
to World Preservation Foundation Senior Scientist Gerard 
Wedderburn-Bisshop, one of the leading sources of black carbon is the 
deforestation that occurs to clear agricultural land, 70% of which is 
used for livestock raising. 
California Resource Board, Dr. 
Ramanathan and Dr. Bisshop, many thanks for helping us understand the 
role of black carbon in climate change. May we each act to reduce this 
and other potent greenhouse gas sources for their Earth balancing 
benefit to all lives. 
Speaking during an October 2009 
videoconference in Indonesia, Supreme Master Ching Hai addressed the 
changes needed to most effectively reduce planet-warming substances such
 as black carbon. 
Supreme Master Ching Hai :
 Now, methane and black carbon are what scientists call short-lived 
gases, meaning, although they are very potent climate warmers, they 
dissipate and exit the atmosphere very quickly. 
The United 
Nations Food and Agriculture Organization said that the livestock 
industry is the major cause of the most pressing world problems, namely,
 global warming, land degradation, air and water pollution, and loss of 
biodiversity. 
With no animal breeding industries, we immediately
 stop the number one cause of greenhouse gas emissions. Not just CO2, 
not just carbon dioxide, but also methane, nitrous oxide, black carbon 
from burning down the trees for the livestock, and also toxic gases like
 hydrogen sulfide. 
If the world's people all become vegans, we will see a dramatic change in a short period of time, a couple of months, yes. 
These changes would be just the beginning signs of a real Eden on Earth.
