A student of the Sri Lankan ancient martial art “Angampora” performs during a practice session at the angam maduwa or fighting field, in Korathota, a suburb of Colombo, Sri Lanka, 07 September 2022. Sri Lanka's ancient martial art, Angampora, is thought to be thousands of years old. Anga translates to “body parts” and Angampora is a fighting art that uses body parts. Martial arts practitioners in Angampora were mostly in the king's service, and they were tasked with protecting the king and his kingdom. Angampora was practiced in secret for most centuries because the British, who colonized Sri Lanka, banned it in 1818 after seeing it as a threat. (Photo by Chamila Karunarathne/EPA/EFE)

Growing cities, overuse of fertilizers and factory wastewater have degraded China's water supplies to the extent that half the nation's rivers and lakes are severely polluted. China aims to spend $850 billion to improve filthy water supplies over the next decade, but even such huge outlays may do little to reverse damage caused by decades of pollution and overuse in Beijing's push for rapid economic growth.
