Trees For Good Health?
The Journal of Environmental pollution has published new research. The headline – Fresh air saves lives. Within just a year, trees have prevented about 650,000 cases of respiratory symptoms and saved about 800 lives. Trees are said to clean the air we breathe making the environment safer for us to live in.
We are all conscious of our health. We fight obesity and other diseases as naturally as possible but we question everything that’s offered before we actually taking it in. For example, natural fat burners are said to be safe for people who want to lose weight but before we accept that we ask – Do fat burner cause health issues? But this is just one among many concerns that we are facing in relation to health. We also know that we need a clean environment to live healthily.
To Plant New Trees Or To Save Existing Ones?
A clean and healthy environment. We all want that. That’s why many environmentalists and concerned citizens are making every effort to save the planet and one of them is to save the trees. But why not just plant new trees?
Planting as many new trees as possible slows down or even reverses climate change – that sounds good in theory. Forests are essential for our climate because they store large amounts of the greenhouse gas CO2.
Plant trees against climate change?
Our trees and forests are essential for the climate because they absorb the greenhouse gas CO2 and release oxygen. Thereby they help to keep the temperatures on earth stable. The more trees there are, the more CO2 can consequently be bound. And intact forests not only help the climate but are also the habitat of numerous animals and plants and thus contribute to biodiversity.
Planting trees for the climate
Some experts believe that reforestation by planting new trees “aimlessly” is not the best way to stop climate change. This is why not all environmental protection organizations have reforestation projects in their program.
A tree has to grow and needs care
Before a tree can bind enough CO2 and dirt from the atmosphere, it has to grow. Because the older the trees are, the more CO2 they can store. A tree cannot develop its positive climate effect immediately after it has been planted – but only after several years. In addition, a tree needs water and care to grow.
Not all trees are the same
Not every tree species stores the same amount of CO2. Spruce, for example, absorbs less CO2 than pine, oak, or beech. Since the climatic conditions change due to climate change, it has to be checked again and again, which trees should best be planted on which soils, and in which regions.
Mixed forests instead of monocultures
Mixed forests also store better CO2 than monocultures and at the same time, less susceptible to pests such as the bark beetle. Monocultures also fall victim to weather phenomena such as storms but recover more quickly than mixed forests, which are more permanent. It is therefore only partially recommended for the climate to reforest tree plantations with the same tree species.
Better to protect forests instead of planting new trees!
Afforestation and new trees are one way to do something about climate change. But what helps even faster and better is to protect the existing forests and, above all, to take stronger action against deforestation of the rainforest. Because better than any newly planted tree is the tree we keep.
