Tree of Life

Trees capture a little of our Sun, harvest it via photosynthesis and makes almost everything we depend on possible. It provides the Oxygen we breath and created just the right atmosphere which has 21% oxygen, not too much and not too little. They also perspired water vapour and create climatic conditions that allow enough humidity to create rain. Trees protect the soil, allowing microbes and other larger animals to flourish on its products. They capture water in their roots and the earth in shade can hold enough water to sustain life and allows the retention of more and more water, giving us water sources that can feed our agrarian needs and our other needs. The trees slow down falling rain, allowing a sponge effect as the water falls through the foliage which protects the earth and the sensitive layer of humus that is necessary for life to feed on where bacteria can nourish the earth with nutrients for other life.

 

 

Carbon forms the key component for all known life on Earth. Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen, and carbon is able to bond with all of these because of its four valence electrons. Carbon is abundant on earth. But too releasing too much of it back to the atmosphere has already increased the carbon concentration beyond the accepted standards, increasing the effects of global warming as CO2 is a green house gas. And trees are vital in recapturing and storing the excess carbon in our atmosphere and regulate and cleanse the air we breath from pollutants.

I will end this brief sojourn into the role of trees in the world around us with a quote I heard recently which goes “why do we always want to park in the shade but never find time to plant a tree”, which just highlights how much we depend on trees yet do so little to protect them. Trees are part of our life and will continue to be so. One day if there are no more trees, there will be no life on earth too.
