Queen Elizabeth presented broadcaster David Attenborough with an award for his hit BBC nature series Blue Planet II, which raised public awareness around the world of the danger of plastic pollution in oceans.
Attenborough, who like the monarch is 93 years old, was awarded the Chatham House prize along with the BBC Studios Natural History Unit for “the galvanizing impact” of the series, the London-based international affairs think tank said.
The annual Chatham House Prize honours people or organizations deemed to have made the most significant contribution to the improvement of international relations.
In the wake of the series, the issue of overuse of single-use plastic suddenly leapt to the top of the news agenda in Britain, resulting in the government announcing measures to reduce plastic use.
