Plants in Peril
Almost 40% of Earth’s plant species are now at risk of extinction due to human activities, according to Britain’s Royal Botanic Gardens, Kew. Its latest annual report on the state of the world’s plants and fungi says more than twice as many plants are at risk than previously thought. It points to agriculture and aquaculture threatening a third of the plants at risk, while climate change appears to threaten only about 4%. The Kew researchers say some of the plants in danger hold great promise for medicine, fuel and food.
