One herd doesn’t value human life much: BBC on geo-engineering and urban food production:
“Schemes to tackle climate change could prove disastrous for billions of people, but might be required for the good of the planet, scientists say. That is the conclusion of a new set of studies into what’s become known as geo-engineering.”
Who determines “What is good for the planet”? Humans. Who decides that wigftp justifies damaging up to 4 billion people? Those same humans. Have the 4 billion been consulted? No.

“Urban agriculture is playing an increasingly important role in global food security, a study has suggested.
“Dr Drechsel said that when urban farming was compared with other (ie rural) farming systems, the results were surprising. For example, the total area of rice farming in South Asia was smaller than what was being cultivated in urban areas around the globe.
“Likewise, total maize production in sub-Saharan Africa was not as large as the area under cultivation in urban areas around the world.”
