The 21st of March 2021 is International Day of Forests, as well as World Planting Day. Trees are so important to us and benefit us in so many ways.
They store CO2
Trees are such a big deal to us because they absorb atmospheric CO2, for photosynthesis, whilst giving us oxygen to breathe. This is why it’s so good if you can be vegetarian because farmers have to chop down trees in order to create space for cattle. Fast-growing trees are great because they can store carbon relatively quickly, but slow-growing trees will end up storing more carbon as they live longer. This is why ancient trees are sometimes protected – they store lots of carbon!
They prevent soil erosion
There are two ways that I’m going to talk about here. The first way is that tree roots keep the soil bound together. Having roots in the soil means that, when it rains, the water won’t just sit on top, it will go through the pores of the soil. This will also prevent flooding!
Trees protect the soil from rain and wind which are two of the worst things for soil. A tree can act as a windbreaker and as an interception for the rain. Wind could cause the soil to blow away and the rain will, once again, cause flooding. A tree will give somewhere for the rain to go and will stop them from reaching the momentum it would take to push the soil particles apart.
They cool cities
If you’ve never studied geography, you might be thinking how? Well, cities can be known as Urban Heat Islands (UHIs). This is where they are a warmer temperature than the surrounding areas, such as suburban and rural. Trees can reduce temperatures when they release water vapour through evapotranspiration. It is estimated that trees can reduce the temperature of up to 7 degrees! The best trees for this are ones that have canopies, light coloured leaves and/or a large SA. Along with this, they provide shade.
They provide food & jobs
I bet that you eat at least one fruit that grows on a tree regularly. I eat an apple everyday, you might eat oranges, lemons, bananas etc. Even if you don’t eat from fruit trees, they provide food for nature who are equally as important as us. Farmers earn money from fruit that grows on trees so they also provides for the economy.
They are good for our health
Watching trees change colour throughout the seasons is always something I like watching, whether that be from my window or outside. Flowers are sometimes given to hospital patients because they make us feel better – trees are the same!
It isn’t just our mental health that they help, they also reduce pollution. Tree canopies trap/absorb dust and pollutants and reduce noise pollution. Medicines have been found from trees and their leaves and many are still undiscovered.
Without trees, we couldn’t live.
They boost biodiversity
Trees are one of the most diverse habitats. There are so many places for organisms to live…in the canopy, branches, leaves, flowers, trunk etc. They also provide food & a place to hide from predators or prey. Did you know that one mature Oak tree can be a home to 500 different species? So cool!
On my blog, I try to provide lots of tips to share & help others become more eco-friendly. But, every now and again, I think it’s important to share info about why we should be caring for the environment & what it does for us. Hope you enjoyed 💚
