Letter: Plant a tree, and cool the Earth


There is a cheap and immediately effective way to reduce temperatures in the troposphere without spending borrowed federal money on big, complicated projects that will take decades and longer to have an effect.

It’s simple, plant trees, a trillion trees to partly replace the trillions of trees destroyed since the beginning of civilization some 12,000 years ago. Trees and green plants absorb carbon dioxide (CO2) from the atmosphere. Everyone knows that. Planting trees reduces global warming by removing CO2 from the atmosphere.

More important, trees take heat out of the atmosphere, lowering the Earth’s temperature. That is because photosynthesis is endothermic; that means photosynthesis absorbs the sun’s energy. Trees take water and nutrients from the soil, then use the sun’s energy to break down CO2 from the atmosphere and make branches, leaves, flowers, seeds, and roots. Oxygen, too. The sun’s energy never heats the ground; therefore, the planet stays cooler. Trees actually cool the Earth!

While America coverts to cleaner electricity with solar panels and more hydro-electric damns we can start to reduce global warming immediately, with the first tree planted. Plant a tree today; begin cooling the Earth tomorrow. What could be better?
