Russia produces the most oxygen in the world

Russia's main export may be energy but that doesn't change the fact that they are also the largest oxygen producer in the world. With over 17,098,242 square kilometers of land, Russia is the largest country in the world by quite a large margin (Canada is second with 9,984,670 square kilometers). As a result, they lead the world in density of trees with about 640 billion trees throughout the country. Trees play a crucial role in supporting and nurturing life around the world by absorbing carbon dioxide and releasing oxygen into the atmosphere.
