We breathe all the time without thinking about it. In fact, we do it 17 Times per Minute. Without breathing there is no life, because every cell in our body needs oxygen from the air in order to function. The volume of air that flows every day through our lungs, is 12,000 litres – more than eight full baths. Since the oxygen content of air is 21 percent and only a part of what we inhale is, in fact, in our body, he uses only 25,5 liters of oxygen per hour.
photosynthesis produces oxygen
With every breath we take, so our ambient air, some oxygen. Nevertheless, we always have enough air to Breathe, the oxygen content of the air remains constant. Because plants are the supplier of Oxygen for our earth; they create it by using sun light and water in a biochemical process called photosynthesis.
The amount of oxygen produced by a tree depends on the species of tree, whose wood density and its age. In General, the following applies: A coniferous tree produces more oxygen than a broadleaf tree and a young tree more than an age. On average, a hundred year old tree per hour to 12,000 litres of oxygen in the air. If a man and so it requires 24 liters of oxygen per hour, could deliver a tree fifty people air to Breathe.
That sounds like a lot – and almost as we would have to make the trees of the earth no Worries, there is enough for everyone. But this is a fallacy: trees not only supply vital oxygen, also carbon dioxide (CO2) that is released when you Breathe in the air handle. In fact, we produce ten to twenty liters of carbon dioxide per hour, a tree can be processed in the same time, 1,800 liters of this Gas and hence the CO2-emissions of 120 people bind.
energy demand in Germany
However, We not only breathe, we are driving the car, showering, heating and switch the light out at night – all that energy is consumed. The hourly CO2 emissions for a Person in Germany is a little over 900 litres. This shows that, Theoretically, a tree could bind the CO2 emissions of 120 people. Be taken into account but our profligate life-style of over a hundred people just two – a sobering result. Every second German would need a hundred-year-old tree in his garden, to the CO2 to compensate for emissions. For this reason, the world advises intergovernmental panel on climate change, to reduce the emissions of each individual on the planet to two tons per year; the equivalent of the just 170 liters per hour. That would mean that we need to reduce our energy consumption to a fifth.
So: lights off, heating down, turn, and in the best case, plant a tree. Who does not see the forest for the trees, can go in good conscience with the car to get to work.
