Now you’ve got a good reason to turn off the camera during your video chats

According to a new study from MIT, Yale, and Purdue University, those video calls are bad for the environment. According to researchers, just one hour in a video conference or streaming shows in high-definition emits between 150 and 1,000 grams of carbon dioxide and requires two to 12 liters of water. However, leaving your camera off during calls will reduce your carbon footprint by 96%. And streaming in standard definition rather than HD could bring an 86% reduction, according to researchers.
