These words appear in the poem The Heart of the Tree's last verse. According to the words, a man who plants a tree holds in his grasp the growth of "all our country" (the entire planet, human civilisation). "Hollow of his hand" refers to the palm of his hand, which is the most protected area. It is here that one finds the greatest number of blood vessels and nerves. This interpretation comes from the idea that planting a tree is like giving birth to it: both processes are initiated by a small seed or piece of wood that grows into a complete plant. In fact, the poet was probably alluding to the belief that if you put your hand into a riverbank or forest ground, you can feel the life flowing out of plants and returning to the earth. This flow of energy is what gives rise to new life. Trees provide us with many benefits, but perhaps the most important is their ability to absorb carbon dioxide from the atmosphere and store it for centuries. In fact, trees play an essential role in combating climate change because they soak up CO2 while we burn fossil fuels like oil and coal, which release this gas into the atmosphere. By storing this gas, they help mitigate some of the effects of global warming. In conclusion, planting a tree is like giving birth to it: both processes are initiated by a small seed or piece of wood that grows into a complete plant.
