Greyboy, Friend, it is a question of perspective. Letââ¬â¢s look at your post ââ¬â it tells me that you are a very decent fellow and I laud your concern forthe Earth, but a little perspective may be warranted. Each time you exhale, your exhalation breath contains about 40,000 parts of CO2 per million parts of air (40,000 ppm). You exhale about 12 times per minute. Your exhalation breath is about 500 ml of air. That means that every minute, as a matter of just living, you exhale about 450 mg of CO2 into the atmosphere. OK ââ¬â now imagine that the 6,803,042,109 of our brothers and sisters across the globe are doing the same thing ââ¬â just breathing. That means that every MINUTE the average loading to the Earthââ¬â¢s atmosphere, contributed by humans doing nothing more than just breathing is about 3,100 metric tons every MINUTE of every day. Thatââ¬â¢s over 184 THOUSAND METRIC TONNES per hour and thatââ¬â¢s just from humans breathing. And you are concerned about ââ¬Åâ⬦pumping tons and tons of carbon into the air we breathâ⬦ââ¬
