Plant More Trees!

One goal of Earth Day 1990 is to have every one of us plant at least one tree. That's a good goal to start with. Some are already going further. Scientist James Lovelock, who originated the Gaia theory that the earth operates like a living organism, has, with his family, planted 20,000 trees. All of us concerned about the earth could consider, like Lovelock and Baker, putting our spades where our worries are.
Why? Since trees absorb carbon dioxide and give off oxygen, they are essential for combating the global warming effect being created by excess carbon dioxide generation. Since they retain water in the soil and transpire moisture into the air, they are—in part—responsible for the ongoing existence of many springs, the even flow of rivers, and the formation of rain clouds. Since their innumerable roots hold soil in place and their bodies block wind, they are the best of all means for stopping erosion. Indeed, since they continually pull nutrients from the subsoils and drop organic matter to the earth, they are unparalleled soil builders as well.
But that isn't all. Consider that:
A single mature tree absorbs around 13 pounds of carbon dioxide a year, while a younger, actively growing tree may absorb up to 26 pounds of CO2, per year—approximately five tons per acre of trees.
About half of the weight of any tree is carbon. To maximize the amount of carbon dioxide absorbed, trees should be planted that gain weight the fastest. Depending on the trees' densities, these may or may not be the same ones that gain diameter the fastest. Some common trees that "bulk up" quickly (in various parts of the country) include river birch, sycamore, tulip poplar, willow oak, red maple (commercial varieties), green ash, and black gum. In the South, try lobolly pine; in the West, Douglas fir; and in the Deep South and the tropics, leucaena. If in doubt, plant any native species that generally do well locally.
Reducing atmospheric CO2 through tree planting costs about 0.3¢ to 1.3¢ per pound. Doing the same thing, by improving the energy efficiency of appliances costs about 2.5¢ for each pound of CO2; and by improving electrical supply efficiency, about 10¢ per pound. While tree planting can make a significant contribution to reducing CO2 buildup, it won't solve the problem, not unless we all turn into Johnny Appleseeds. For it to do so, we would have to replant all the planet's deforested areas—or double the growth rate of existing forests—to compensate for humanity's excess carbon dioxide production. It's been estimated that a typical family of four would need to plant six acres of trees to offset its CO2 generation.
In many locations, the cooling effects of trees can be more important than their ability to absorb carbon. Using landscape trees to shade buildings (and thus decrease the need for air-conditioning) results in CO2 , emission reductions that are 15 times as great as the amount of the trees alone can absorb. Indeed, shade trees on the south and west sides of a house can lower its air-conditioning bills by up to half.
Cities are particularly important locales for new tree-planting efforts. All that concrete and asphalt creates a "heat island" that makes cities 5° to 9° warmer than surrounding areas, so the cooling effects of trees can be especially helpful. The American Forestry Association estimates that there are 100 million tree-planting sites available. Planting them all would reduce carbon dioxide emissions from energy production by about 18 million tons per year and save consumers $4 billion each year in energy costs.
All well and good. However, planting a tree is not quite as simple as it may sound. Without proper technique and care, a transplanted tree will die. Hence, how about you take up this responsibility on your shoulders, to be one of those heroes saving our beautiful planet earth?
