In this TED presentation, scientist Allan Savory can't resist the temptation to spread the mindless and gratuitous climate fear-mongering that has become so predictable and boring. Putting aside that, his science regarding intelligent land-use is fascinating.
His claims that better livestock policies will "lock" carbon into the soil, thus reversing never-ending, natural global climate change is fundamentally ludicrous, but his research experience does indicate that huge local climate changes are possible.
Indeed, it would appear cows are capable of changing desert-like conditions into a grassy savanah. And from his research, it is obvious that desertification is primarily the result of stupid land-use polices versus alarmist speculations that human CO2 emissions are the cause.
Special note: Prior to this man finally developing his intelligent land-use/livestock policies, he had 40,000 elephants shot in a failed effort to implement policies based on the experts' "consensus" science of the time. Now add to that carnage the millions of African deaths due to the scientific consensus-stupdity regarding DDT, one can then safely surmise that scientists from around the world turned Africa into the proverbial 'killing fields' for both man and beast.
A video well worth the watch.
