After decades of "Geoengineering" or spraying aluminum, barium, etc in to the atmosphere under the guise of protecting us from the sun's radiation also known as chemtrails the poisoning of the planet and side affects are going to be so devastating that our efforts in reducing our carbon footprints and the like will be meaningless.
Many people still think that this is not happening even now when governments are openly admitting they are doing it. This needs to stop so the planet can recover.
