Based on a recent study from a group of researchers at McGill University, Scientific American says that they calculated “global human day” revealing that which activities take most of our time.

• “Every human on Earth has the same 24 hours to spend in a day—but the way we divide those hours for work and sleep and school and play varies a lot. Scientists recently compiled the available data about how people around the world allocate their time and used them to define the average “global human day.” 
• “More than a third of our hours are spent in bed, they found, with the rest split among three categories the researchers devised based on whether the time directly affected humans, the physical world, or where and what people are doing.
• “Activities such as agriculture took up much more time in poorer countries than in wealthier ones, whereas others such as human transportation were fairly constant everywhere.
• “Rrelatively little time—about five minutes per average human day—goes to activities that directly alter the environment and climate change, such as extracting energy and dealing with waste, suggesting an opportunity to put in more time to help the planet.

The study co-author Eric Galbraith, told the Scientific American, “We have to switch off fossil-fuel energy and construct more renewables. If it turned out that the changes we want to make required huge allocations of time to activities we’re not doing now, then it would be impossible. But we can tackle this with just a couple of minutes per day. I think that’s hopeful.”
