Ethiopia Says It Planted Over 350 Million Trees in a Day, a Record

Grey water and septic water are just fine on trees. Tree root systems are natural bio filters. What they've done is start the wheels turning a localized eco-system which will hopefully propagate and survive.

Trees, brush, etc are part of the long term carbon cycle that secure carbon (CO2) from the atmosphere.

In addition to the watering I hope there is scientific monitoring of the efforts as well.

but the real benefactor was the lumber companies.
I had more than a few twinges of conscience.
So I got a job as a planter. We had large, mailbag sized bags
filled with seedlings, about 14-16 inches. Doug fir.
We lined up about 10 or 12 feet apart, with our bags slung over
our shoulders, and a hoedad or small hoe/pick in our hands.
10 steps, swing the hoedad down and pry the ground open.
Insert the seedling, tamp the soil with your foot and take
10 more steps.
I went back some years later to some of the places and the trees had
taken off.

350 million seedlings at one time? For that matter, where would anyone get such a large number?

combat climate change .

Anything that grows holds soil and controls erosion. The bonus is the shade which helps drop the local temperature a few degrees.

Whenever I hike or walk I carry a bag with me. When I find acorns, hickory nuts, beechnuts, apples, pears, cherries or even maple seeds I fill the bag. Then I take it to a brushy area that is underutilized and scatter them amongst the brush. I try to guess areas that won't be developed like hedge rows and property lines, steep stream banks. Couple of times I've cleaned the maple seeds out of my gutters and moved sprouts to open vacant fields. If you throw them into brushy areas, the brush acts as a natural deer block and the sprouts actually have a chance. I done this as a hobby for 20+ years. I'd like to think some of the small trees along the trails I walk are from my efforts. If one in 10,000 seeds I've thrown grows into a mature tree it will have been worth it.

As a goofy side note, as I look for seeds in the more formal parks, I'm up about $40 in coin change, returnable bottle & cans plus a really cool Swiss Army knife and a watch. Some people also have to pick up after their dogs.

Wife says some of my best friends are nuts,

Millions of Americans go into the forest every week. If a trend is started to bring a few seedlings with you and plant them, the impact could be huge. Provide people with a little knowledge on what to plant and where and the impact would be bigger. There is so much abandoned farmland in this country that is now just fields. Filling in thousands of those fields with trees would have a tangible impact on the environment.

Trees are a huge weapon to fight global warming. They also clean the water, control erosion, promote wild life, and can even help the weather.

I for one am going to follow your lead, it would be easy enough to nurture some seedlings from the trees in our yards and then pplant them in the wild when I get the chance.

...............go nuts!

well some good coffee comes from Ethiopia, hope they planted lots of coffee trees.

Great lesson for school kids to learn about climate change and the environment. I would've loved this when I was a kid.

Is that an arid climate?
