A study reveals that wild relatives of crops such as corn, beans, and potatoes, which are crucial for food security and the development of new varieties with pest and drought resistance, are increasingly endangered. The research, focusing on nine species from the Mesoamerican region, found that 35% are endangered according to the IUCN Red List, with some wild vanilla varieties, 92% of cotton, and 60% of avocados facing extinction. The main causes include overproduction and the use of pesticides. The authors emphasize the importance of representing these wild relatives in gene banks to develop more resilient crops and adapt to climate change.
