Australia’s 2019-2020 bushfire season was unprecedented, even in a country used to seasonal wildfires. Over 46 million acres of land was burnt, 36 people were killed, and another 445 died indirectly, following smoke inhalation. An estimated 3 billion animals were killed or displaced, and the fires destroyed almost six thousand buildings. They were also known to have released massive amounts of carbon dioxide into the atmosphere, but estimates of the total emissions have been uncertain. However, a new study using high-resolution satellite measurements atmospheric gases, suggests as many as five previous estimates of the CO2 output from the fires only accounted for less than half of the total emissions. It is now believed the bush fires, known as the “Black Summer” fires”, released 750 terragrams (750 million tonnes) of CO2 into the atmosphere between November 2019 and January 2020.

Food-based agriculture accounts for more than a third of all the greenhouse gas emissions that drive climate change, and farming for an animal-based diet adds up to at least 57% of that. Could a change of diet be useful?
