How Many Trees Can We Plant in 12 Years?

I am very glad to hear Alexandria Ocasio Cortez, and Rashida  Tlaib, and some of the other new firebrands in the U.S. House of Representatives, talking about a Green New Deal, because that’s exactly what’s needed.  Not just in the U.S., but around the world, if we are to beat that 12 year deadline and save the world.
Fortunately, the U.S. is not the whole world and there are other countries who are showing the way.  Also fortunately, many of the things we need to do will cost very little money.  For  instance, planting trees.
New Zealand has announced plans to plant 100 million trees per year.  I’m not sure how many years they plan to keep it up for, but if it’s more than one or two, that’s a hell of a lot of trees for a small country with two islands.  China is planning to plant a forest the size of Ireland on previously treeless land, and India can bring out tens  of thousands of volunteers to plant 100,000 trees in a day.  These are magnificent efforts and if the rest of the world follows suit, a lot of the carbon particles will  be scrubbed from the air, which will be cooler and shadier.
Trees have lots of side benefits as well.  Fruit,  nuts, sap, wood (although we’d be wise to use less of that until we’ve reforested the world properly), and homes for birds.  If the birds survive, humanity will survive.
Every city needs more trees, because a quiet, tree lined street is such a much more pleasant place to live than a stark, barren, concrete or trimmed grass strip between the buildings and the speeding cars.
Once upon a time, before the advent of agriculture, civilization, and races of men determined to bring the planet to heel, pretty much all of Europe north of the Alps was dense forest, and almost all of North America east of  the Mississippi and south of Hudson Bay as well.  Admittedly, there are now cities and farms, we may never again be a purely  wild planet, but we should try to recreate that native state as closely as possible.
