Why did India and England players wear green armbands in 3rd ODI in Ahmedabad?

India and England players wore green armbands on Wednesday in the third ODI at Narendra Modi Stadium. It was to support 'Donate Organs, Save Lives' initiative. The initiative is spearheaded by ICC Chairman Jay Shah. Earlier, BCCI shared a video wherein Virat Kohli said, "Your organs can help others live beyond your lifetime. Register as...donor and make every life count."
