On March 23, 2013, Yeh spoke out on climate change and global warming during Earth Hour, the one hour when the World Wildlife Fund (WWF) encourages businesses and households worldwide to switch off their lights to raise awareness on climate change. Sea turtle eggs are influenced by a biological process known as Temperature-dependent sex determination, meaning that their gender is determined by the environmental temperature. Yeh reminded the public, “As the global climate’s average temperature increases, more females will be hatched, jeopardizing sea turtle populations with an unbalanced sex ratio.”
