In a study published in the journal 
Nature Geoscience, US-based lead author Dr. Ruth DeFries discovered that
 along with an increased move to cities has been a rise in the clearing 
of forests.
This observation reverses previously held beliefs 
that fast-growing urbanization and technological efficiencies might slow
 or even reverse such deforestation. 
Moreover, the research 
found that the trees’ decline is due in part to the tendency of 
city-dwellers to eat more animal products and processed foods. 
Dr.
 DeFries stated, “One line of thinking was that concentrating people in 
cities would leave a lot more room for nature. But those people in 
cities and the rest of the world need to be fed. 
That creates a 
demand for industrial-scale clearing.” Some of the nations most affected
 by the immense land clearing needed for livestock and related products 
include Brazil, Paraguay, Indonesia and Cambodia. 
Related 
research has found that in Brazil alone, more than 80% of the deforested
 regions are occupied by cattle or crops grown for animal feed. 
Our
 sincere appreciation, Dr. DeFries and colleagues, for your work in 
documenting further the immense eco-damage created by meat consumption. 
May
 such findings hasten our actions toward life-giving plant-based fare to
 save our Earth. 
Highlighting as on previous occasions the 
preciousness of our planet’s biodiversity, Supreme Master Ching Hai 
addressed once more the need to halt the destructive tolls of the 
livestock industry during an October 2009 videoconference in Formosa 
(Taiwan).
Supreme
 Master Ching Hai: Right now, one-third of the entire Earth’s 
land surface is used either for grazing animals or growing feed for the 
animals, not for humans. We humans use very little of this agriculture 
section. 
This is a devastating way to make a cheap profit at the
 cost of our planet’s and our people’s survival. We are eating our 
planet by consuming meat. So, without the needless animal industry, not 
only will we gain forests, we can also have organic vegan farmlands to 
grow real, decent food for humans, and like the forests, these farmlands
 can also absorb a lot of heat, a lot of heat from the atmosphere. 
And
 a global shift to organic vegan practices could mean 40% of all 
greenhouse gases absorbed as well, apart from the 50 plus percent that 
we eliminate through the terminating of the animals raising practice.
