This article is right up "Zen Practice's" alley.
It has a lot of good info, to be sure; yet there is a particular form of tunnel vision that always shows up in articles focused on ONE main criterion.
"The situation is only likely to worsen, with food production expected to double by 2050 according to the FAO, as the global population expands and meat consumption per capita rises and more people move into the middle classes."
How can ANYONE speak definitively of projections into 2050 when the earth's rising temperature is already seeing the awakening of long-dormant volcanoes, massive floods and reciprocal droughts, millions of refugees of war, and a continued corporate stranglehold held in place by Big Pharma., the big banks, MIC, Big Media, and Big Oil/coal/gas? The entities with the greatest influence over decisions that pertain to us all are prepared to cash in humanity's population pool in order that THEY reap immediate untold profits.
Escaping methane (a stronger facilitator to global warming than CO2), Fukushima's radioactive breath still "exhaling" death, spreading oceanic dead zones, saber rattling towards a WW III... and a thirty-five year projection seems quite optimistic.
Granted, the emphasis on meat-eating is taking a toll on The Great Mother; but to place this item above WAR--as featured widely across the global "menu"--seems odd.
If the water is tainted, or rains don't fall at all... no cattle will be in place to feed McDonald's and Burger King-trained appetites.
This problem includes meat-eating, but it's hardly limited to that. And I don't eat meat...
