Without Plants, Earth Would Cook Under Billions of Tons of Additional Carbon

Scientists and botanists alike agree that plants, but more specifically trees, are single handily responsible for helping to keep our planet from growing hot due to build up of carbon in our atmosphere. Starting again in the mid-twentieth century, americans in particular began to concern themselves with conservation and began major initiatives to grow our forests. The growth in forests over the last 70 years has been estimated to have cut down close to 192 billion tons of carbon in our atmosphere that would otherwise be threatening to our global temperatures.
