It has emerged that there isn’t adequate space on Earth to plant the number of trees needed to prevent the climate from warming by 3.6 degrees Fahrenheit. Studies indicate that we emit about 30 to 40 billion tons of carbon dioxide-the greenhouse gas into the atmosphere each year. If we continue at this rate, Earth will continue to heat up and in due course devastate our way of life.
What needs to be done?
A majority of scientists agree that we need to devise a method to capture some of this CO2 from the atmosphere. The first idea is to plant lots of trees as they use CO2 in order to grow and also release advantageous oxygen, so it’s a win-win.
But recent studies show that we may not be able to grow enough trees needed to capture the necessary amount of CO2 that would help us meet the goals laid out by the Paris Agreement.
In actual fact, we probably need to cover the entire contiguous US with trees just to tap 10% of the CO2 human emit annually. There’s simply not enough room on Earth’s surface to have the farmlands required to feed the world and the space to plant the necessary number of trees.
Simply put, many of us would starve if we tried using just trees to solve our emissions problem.
