American Museum of Natural History’s second annual Earth Day video is a playful animated infographic comparing changes—good and bad—in the Earth’s health, from 1970 (year of the first Earth Day) and to today. This year’s video focuses on oceans, tapping into decades of data on sea surface temperatures; sea ice; population sizes of marine species; coral loss; plastics in the oceans, and more. It also illustrates promising developments, and helps viewers find ways to take positive actions.
