Microsoft co-founder Bill Gates recently suggested that rich countries should eat only synthetic or plant-based meat. Synthetic meat is grown in a lab from animal cells, while plant-based meat is created from plant and other non-animal ingredients. Gates added that the world’s 80 poorest countries should still eat real meat.

In Gates’ new book, he says that it’s impossible to completely get rid of the greenhouse gases that come from cows and the fertilizers used for the grass that they eat. In the US, 10% of the total greenhouse gases come from farming. To lessen them, Gates believes that countries should switch to eating only synthetic or plant-based meat.

According to Gates, the taste of synthetic and plant-based meat is different from real meat, but manufacturers are trying to improve it. Some plant-based meat companies have also made their products more affordable and easily available. Impossible Foods now offers a set of two burger patties for $5.49 (about ¥600) and a 340-gram pack of ground beef for $6.99 (about ¥765). A similar company, Beyond Meat, has partnered with Walmart to sell its products in more than 2,400 stores.
