Few interesting points from the Matt Reynolds article in WIRED:
In 2021 the polling firm Ipsos asked 21,000 people in 30 countries to choose from a list of nine actions which ones they thought would most reduce greenhouse gas emissions for individuals living in a richer country. Most people picked recycling, followed by buying renewable energy, switching to an electric/hybrid car, and opting for low-energy light bulbs. When these actions were ranked by their actual impact on emissions, recycling was third-from-bottom and low-energy light bulbs were last. None of the top-three options selected by people appeared in the “real” top three when ranked by greenhouse gas reductions, which were having one fewer child, not having a car, and avoiding one long-distance flight.
beef and dairy have two of the highest carbon footprints of any food.
Organic farms tend to be better for local biodiversity, but because they produce less food per acre they’re bad for land use. The EU has set itself the target of making 25 percent of its farmland organic by 2030, but this could reduce its production by between 7 and 12 percent, forcing more land to be converted to agriculture elsewhere in the world
