What do you know about the benefits, their function and value of trees to mankind?

Without going into many details, I just would like to highlight the more important things what a tree has to offer to us. On our own 10-acre property in the Fraser Valley of British Columbia, Canada we have a huge variety of balsam fir, douglas fir, hemlock, alder, red cedar, maple trees and all of them have medicinal value!

Years ago, a Native Indian woman did ask me: “Did you ever hug a tree especially if the wind is whistling in their crown?” I had to deny it but a few days later used the opportunity hugging a huge douglas fir tree when a strong wind was blowing and the experience was really amazing and I had goose bumps on my back and realized how small and unimportant I was compared to the tree! I you have never experienced it, please give it a try!

Humans on our planet would be unable to live without tree and what are their major benefits?

Trees have been around since the earth started, some of them can be as old as 10,000 years, for example the Gingko Biloba tree in China, the Neem tree 4,500 years and you have probably seen pictures of old growth forest, real giants up to 364 feet!! In my book “Neem – Nature’s Healing Gift to Humanity” I publish a picture of a Neem tree in Myanmar (Burma) that is 220 years old, 50-meter-high and has a crown of 40 meters! Incredible as it may be the temperature at the top of that Neem tree might be close to fifty-degree celsius and due to the shade, the tree creates the temperature can be up to 10-12 degrees less at the bottom. Because of that it is known that bees prefer to build their hives always at the bottom of a Neem tree in countries with tropical and sub-tropical climate!

Trees combat climate change, clean polluted air and water, provide oxygen, cool streets in the cities, conserve energy, save water, prevent soil erosion and floods, create shade (very important in tropical and subtropical countries). The branches and trunks provide shelter, food, and habitat for mammals, birds, amphibians, insects, and other plants. The sun’s energy is filtered through the leaves to benefit all terrestrial creatures and transpire torrents of water vapor into the atmosphere. Their lives span periods of time that extend far beyond our existence, experience, and memory. They are remarkable beings, even communicate with each other through their roots and give signals in case of hurricanes, earth quacks, fire, drought, heavy rain, temperature change and the older trees take care of the younger and smaller ones! Most people barely notice them and they create a special feeling and comfort you especial in the summer time with hot weather conditions. Do we really treat them with respect that they deserve? I don’t think so! Whenever a new subdivision is created by developers first thing is to cut most or sometimes all the trees. In our own neighborhood, we had huge giant douglas fir and maple trees growing and they are now all gone!! A real sad story!

Trees offer these additional values:

Community and social, ecological and environmental, personal and spiritual, practical and commercial, property values.

Every tree that take roots does carry with it a myriad of benefits for health, quality of life, end well-being – locally and globally!

Unfortunately, we are doing in the amazon areas cutting especially old growth forest is dangerous and life threatening since it is the lung creating oxygen and this has to stop before it is too late!

The miraculous versatile medicinal Neem tree (Azadirachta indica)

For those who are not familiar with the fascinating tree – it is the most extensively studied and researched tree in modern science in the world – but outside Indian scientific community, Neem tree has been virtually unknown in the western world until very recently, here are in a nut shell the benefits, more details you will be able to find in my book “Neem – Nature’s Healing Gift to Humanity”:

All parts of the tree are medicinal, bark, leaves (as extract, tea and tincture), flower, fruit (honey) twigs (used as natural tooth brush), seeds, kernels (oil), seed cake, roots, timber.

Health benefits of the Neem tree
