Daffodils have long been seen as a symbol of Wales – but could they also be used to save the climate?
Researchers are testing a new method of using Wales’ national flower to cut the level of methane produced by livestock.
Methane is the second most common greenhouse gas after CO2, and is released by livestock, such as cows and sheep, when they burp.
Tests show a chemical extracted from daffodils can reduce methane production by a third when added to cow’s feed.
Half of methane emissions in the UK come from cows, while they account for 14% of greenhouse gases globally, BBC’s Countryfile reported.
