What do we get from trees
Why trees are vital to us
City trees are "hard workers"
The trees that stand by our streets in particular do astonishing things: Within an hour, a tree processes around 2.4 kilograms of carbon dioxide. In addition, it binds more than 100 kilograms of dust per year. After up to 400 liters of water has evaporated on a summer day, the humidity increases and we find the cooling of the outside air extremely pleasant. It is no coincidence that we seek refuge in parks in summer and enjoy our coffee in street cafes with old trees. The average temperature in our cities is a few degrees higher than in the country, regardless of the season.
Trees are real "hard workers": The tiny particles of exhaust gases and dust penetrate their stomata. There they attack the tissue of the trees. Not only our health suffers from too much traffic, but also that of the trees. Often only a little water can get to the roots of the trees because there is asphalt around them or our cars are parked.
"After the subalpine habitat shortly before the tree line, the road location is the hardest thing you can expect a tree to do."
Christian Hönig, tree protection specialist at BUND Berlin, sums it up in an article by National Geographic.
The result: life expectancy falls. The Protection Association of German Forests states that trees on roads often only live to 60 years. In parks, however, they can reach around 200 years. A sad result. The strong enrichment of the atmosphere with carbon dioxide from the car exhaust leads to the well-known greenhouse effect. As a result, trees, bushes and flowers start to bloom earlier and earlier.
How can I help the trees?
The Bund für Umwelt und Naturschutz Deutschland e.V. (BUND) gives tips on how you can help our city trees:
- Pay attention to Parking always on the planting and do not connect a bike to the tree. Small injuries to the bark or branches are also injuries. Young trees are hit harder than older, robust specimens.
- The beloved four-legged friend should be Do not lift legs by the tree (at least not always the same).
- The Road salt in winter, which penetrates the earth near the tree, is extremely damaging. Instead of salt, it is better to use other grit.
- You can the earth around the trunk plant, for example with grasses or herbs. This also supports tree health.
- Make one Casting community with your neighbors: Because of the persistent drought, casting communities are forming in more and more cities. They agree who will give water to the tree in the street and when.
Here you will find even more tips on how you can help city trees through the drought:
In addition to its important role as a city tree, the Baum is a real all-rounder. It helps stop climate change, is a habitat for numerous animals and plants and provides us humans with oxygen as well as the raw material wood for numerous purposes.
Trees slow down climate change
Trees have the special ability to Braking climate change by sequestering carbon dioxide. This is due to the photosynthesis that trees use to grow. Our trees absorb the carbon dioxide from the air, which is responsible for climate change. Under the influence of light, they break down the gas into its components and transform it into organic materials (e.g. wood). A tree consumes an average of one ton of carbon dioxide for one cubic meter of wood. And as a by-product of photosynthesis, oxygen, which is vital for us, is created.
Trees as a habitat
Not only for us humans, also for one in general intact nature and biodiversity trees are irreplaceable. Because trees in turn provide important habitats for other plants. These grow in their shade, climb up them or settle on their branches. Countless animal species use them and their fruits as nests and sources of food.
Trees as suppliers of energy and raw materials
For us humans, wood is especially important Energy supplier and material for paper and textile production or for building. But: Many countries are overexploiting their forests. More wood is cleared or set on fire for economic reasons than grows back. The consequence is one annual reduction in forest cover by more than ten million hectares. But there is one ray of hope: In many countries there are initiatives that Reforestation aim and who are committed to protecting the existing forests.
