I feel as though trees absorb negative energy, from us. We are blessed with their presence. They actually absorb carbon dioxide, which we as humans give off and they provide oxygen.
Trees give us oxygen through the process of photosynthesis:
Trees convert carbon dioxide and water into oxygen using sunlight.
The oxygen produced by trees is released into the atmosphere, benefiting animals and humans.
Trees (along with some other very small powerhouse oxygen creators) are one of our planet’s primary producers of oxygen a gas necessary for all life! Before deciding you need more O2 in your life, you might wonder which trees produce the most oxygen. How do they do it?
Maple, beech, true fir, spruce, and Douglas-fir trees produce the most oxygen. They do this using photosynthesis, which converts carbon dioxide into oxygen. Trees help our environment by reducing the effects of climate change, detoxifying poisonous gasses, and balancing atmospheric temperatures.
