Scientists at London’s Royal Botanic Garden have created a list of plants that could become regular foods by 2050. They say it’s important to start eating a wider variety of foods. More than 7,000 plants around the world are edible, but only 417 are commonly grown for food, and the top 15 plants provide 90% of the world’s calories.

One of the plants on the list is the pandanus, a small tree that grows in the Philippines and other Southeast Asian countries. Its fruit is similar to a pineapple, and its leaves are often used in both sweet and savory dishes. Another plant on the list is the enset, an Ethiopian relative of the banana. Its fruit isn’t edible, but other parts can be used to make bread.

Ukraine and Russia are major players in the world’s food supply, so the war in Ukraine has made global food prices skyrocket this year. Over 20 million tons of grain are currently stuck in Ukraine, causing major shortages in countries that rely on its wheat. Climate change is also affecting farmers’ ability to grow food all over the world.
