Your morning cup of coffee is in danger. A study published today Science Advances states that a majority of the world's wild coffees are threatened with extinction. The two main types we rely on in our caffeine fixation – Arabica and Robusta beans – are both threatened by climate change and deforestation.
The British research team used the Red List of Endangered Species of the International Union for Conservation of Nature to classify the risks faced by the world's 124 known wild coffees. About 60 percent – or 75 different species – may be threatened with extinction in the coming decades. This represents "one of the highest values measured for a plant group," the researchers write in their work.
Among other things, the severe droughts associated with climate change and deforestation are to blame. Other threats include the spread of fungal pathogens and the disease of coffee wilt in Central and South America and Africa as well as social and economic factors for growers.
"Considering the threats of human intervention and deforestation, some [coffee species] could be extinct in ten to twenty years, especially due to the added impact of climate change," explains lead author Aaron P. Davis of the Royal Botanic Gardens, Kew, to CNN.
Davis & # 39; s previous research emphasized that Arabica was already listed as an endangered species could have died out within 60 years. Most of the coffee facilities we rely on are farmed, However, wild coffee is no less important: some wild species are resistant to disease and have other beneficial genes that could be used in commercial crops, so the cultivated varieties could better endure the effects of climate change and survive a little longer.
