A few incorrect (though fairly unimportant) claims in the meme here:

Cow poop creates biodiversity. Wrong.  Look up “biodiversity.”

The lifecycle of grass takes CO2 out of the air and replaces it with oxygen.  Throughout a 24-hour cycle, the intakes and outputs of CO2 and oxygen from green plants balance themselves.  Yes, an infinitesimally small amount of CO2 is sequestered for a relatively short period of time (until the cow is processed).  This is why growing trees makes a difference, i.e., the CO2 is sequestered in wood that can be locked into building products lasting decades or centuries.

The meat industry is the single most destructive thing we do with the respect to the planet’s health.  That’s because:

a) The land we’re using comes largely from the destruction of the Earth’s rainforests, often referred to as the planet’s “lungs,” at the rate of 85 acres per minute, and

b) Every cow on Earth belches about 220 pounds of methane per year, a greenhouse gas that is shorter-lived than CO2, but ~28 times more powerful.
