Rays from the Sun are essential to life on Earth, in temperate climes governing the four seasons, also separating night and day. Using energy from sunlight, plants create carbohydrates and other carbon-molecules from water and atmospheric carbon dioxide (CO2) gas by a process called photosynthesis. I learned about photosynthesis in grade school! Little did I then foresee PhDs and big wigs would ever succumb to a tale of global peril owing — not to weapons of mass destruction – but rather to benign CO2 gas! We exhale CO2 with each breath. The only potential harm from our individual CO2 emissions is to alert mosquitoes.
