Today is World Environment Day (WED), and this year’s theme is Seven Billion Dreams. One Planet. Consume with Care. In honor of the day, the UN is asking for everyone to pledge to doing “one thing less” to help reduce our negative environmental impact. Why? Because, as Secretary-General Ban Ki-Moon puts it: "Although individual decisions may seem small in the face of global threats and trends, when billions of people join forces in common purpose, we can make a tremendous difference."
