Today, with the occasion of International Day of Forests, let’s take the time and review few of most important well known benefits of forests for humanity and wildlife alike, to understand importance of fighting for for their long term preservation, in their actual state, limiting current intensive exploration by governments and private companies whose only short term and narrow minded objectives are material profits to benefit few!
Forests help us breath, also clean dirty air and keep the Planet cool: Trees absorb CO2 and emit Oxygen, essential for existence of life on Earth as we know it, whereas CO2 is stored in wood, leaves and soil, often for centuries, delaying global warming and maintaining a fragile ecosystem balance! Today’s combination of high CO2 human activity emissions and cutting down forests is leading to an accelerated global warming, with its associated disasters!
Home of biodiversity: Nearly half of all known species live in forests, estimated at 80% of biodiversity on land, including bugs and worms who work nutrients into soil, bees and birds spread pollen and seeds, and keystone top of the food chain species who keep herbivores in check, protecting on long term the well-being of forest!
Water regulator, as important part of water circuit in nature, refilling aquifers and important role in fighting floods: Large forests can influence multi-regional weather patterns, for example disappearance of Congo basin forest may impact climate on American continent! Regarding floods, tree roots are key allies in heavy rain, especially for low-lying areas like river plains. They help the ground absorb more of a flash flood, reducing soil loss and property damage by slowing the flow. Forests also act like giant sponges, catching runoff rather than letting it roll across the surface, but they can’t absorb all of it. Water that gets past their roots trickles down into aquifers, replenishing groundwater supplies that are important for drinking, sanitation and irrigation around the world.
They block wind: Groups of trees can also serve as a windbreak, providing a buffer for wind-sensitive crops and making it easier for bees to pollinate them.
They keep soil in place and clean dirty soil: A forest’s root network stabilizes huge amounts of soil, bracing the entire ecosystem’s foundation against erosion by wind or water. Not only does deforestation disrupt all that, but the ensuing soil erosion can trigger new, life-threatening problems like landslides and dust storms, or desertification. In addition to holding soil in place, forests may also help cleaning out certain pollutants. Trees can either sequester the toxins away or degrade them to be less dangerous. This is a helpful skill, letting trees absorb sewage overflows, roadside spills or contaminated runoff.
They feed us and give us medicine: Some trees provide fruits, nuts and other seeds and a wealth of natural medicines. The asthma drug comes from cacao trees, for example, while a compound in eastern red cedar needles has been found to fight an infection that resists many antibiotic drugs. About 70 percent of all known plants with cancer-fighting properties occur only in rain forests. Also many other medical benefits are yet to be explored and apply in practice, but large tropical forests disappear today faster than researchers have time to fully grasps all unexplored benefits!
They help explore and relax, reduce noise pollution and stress, lower blood sugar, help with better concentration, diminished pain and improved immunity for humans: Sound fades in forests, making trees a popular natural noise barrier, with just a few well-placed trees being able to cut background sound by about 50%! And because modern society is relatively a new born in evolutionary terms, humans may still feel natural in a forest, rather than a modern urban environment, supporting a multitude of hormones and natural process to occur in our bodies, making us happier people! It may even help us live longer!
Forests are pillars of human communities and here I am not referring to 1% richest of the planet, who probably could live happily in artificial underground palaces, if needed, but to majority 99% whose well-being and survival may depend on preservation of forests, on long term. I am sure through technology the problems as feeding the large population or shelter them may be over-come, but not sure you will feel happier, so it is in our majority interest to fight for a happier and greener future!
