Virtual Open Houses

I just got the following quotation regarding global warming effect. It seems interesting:

The following are a few inconvenient truths that the former V.P. (Al Gore) ignores:

• A major United Nations study determined that the meat industry generates 40 percent more greenhouse-gas emissions than all the cars, trucks, SUVs, ships, and planes in the world combined.
• Researchers at the University of Chicago concluded that going vegan is 50 percent more effective in combating the climate crisis than
  switching to a hybrid car.
• The official handbook of the Live Earth concerts that Gore helped organize acknowledges that not eating meat is “the single most effective thing” you can do to reduce your climate change impact (emphasis in original).
