Being done right now on the front edge of the expanding Gobi Desert, now only 30 miles from Beijing. Works fine. The Chinese have developed a chemical that leaves sand porous to air, but impermeable to water. Great stuff. Jan I hardly think this is a rain forest!!! This is the project next to the Gobi desert you were speaking of. https://www.freshplaza.com/article/2193557/china-hydroponic-soil-free-farming-in-the-gobi-desert/ When you dont have rain every day and there is no leaf mulch to speak of you ain't getting a rain forest! Why do we always look at doing the very difficult when the easy solution is staring us in the face?

Has nothing to do with "consumer patterns in the West." Deforestation of the Amazon has everything to do with consumer patterns in the West.

This waste of a precious natural resource needs to be stopped. The industry refuses to control itself resulting in diminishing margins. A severe penalty for wasted gas is required to stop this practice because the lost opportunity profit is so low there is no motivation to capture this current overabundance. A better alternative would be methanol plant near the source of the excess methane production. Normally I would abhore government involvement but large tax advantage granted to the first x% of new methanol production facility would seem to be worthwhile. Methanol, other chemicals, electricity, gasoline, etc. 2 Quote Share this post Link to post Share on other sites

Just looking for a way to avoid wasting this energy source to flaring and venting while the price of NG is so low. The power required to support the process would be provided by using even more of the NG currently going to waste. The process would also use the concentrated CO2 generated from power plants or even the batteries described here. The oil industry will not give up or even curb production so it seems necessary to develop more and better uses of methane. 1 Quote Share this post Link to post Share on other sites

However how that is implemented around the world particularly poorer countries I don't know.

Surely its a lot easier and cheaper to just stop the deforestation in existing rain forests like the Amazon. FYI "More than 150 acres are lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rain forest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year." 4.6 million acres of irreplaceable Amazon rain forest burned between Jan 19 - Sep 19 and this is ever increasing year on year (Australian fires have burned 12.35 million acres in total). Every 3 years we burn more of the Amazon than this. It would be way cheaper to pay the loggers in these areas a healthy salary than start hydroponics in the Sahara I get Jan's idea but its not practical If you want to help with reducing Co2 then this needs to stop and quickly! We need to get our heads out of our backsides and put pressure on the Brazil government to stop this immediately. We should also come up with economical solutions for the Brazilian loggers to ensure that the Amazon is protected long term. Rant over, and I now sound like Sting! God help me! The amazon rain forest has been getting denuded since I was in junior high. The reason is clear as I was taught back then. The rainfall is so high in that region that soil loses its nutrients immediately upon exposure. The choice of crops Brazil grows don't help matters much. So the locals Illegally burn rainforest as their soil depletes due to leeching. Immediately after a burn, the newly created farmland is exceptionally rich in nutrients and will have massive production for about three years. Then it's ruined and they burn more rainforest; lather, rinse repeat. 1 1 Quote Share this post Link to post Share on other sites

Douglas Buckland + 6,308 January 31, 2020 Personally, I think it is folly to address an environmental situation such as the expanding Sahara (whether it is due to climate cycles or people’s behavior on the fringe) by humans undertaking the role of Mother Nature and doing something crazy like diverting rivers. From what folks are posting, the root cause is once again over population. I’m sure that they addressed this in Davos. 1 Quote Share this post Link to post Share on other sites

GunnysGhost + 157 GI January 31, 2020 (edited) Consider the Pacific Wild Salmon. It is at 1% of its historical breeding population. The 3 'greenest' states and one big 'green' Canadian territory in one of the 'greenest' (most developed) regions of the world have reduced salmon levels by over 99%. We needed 'green' energy for all those people living in these 'green' states so we built a series of 'green' dams which have effectively put the salmon on the pathway to extinction. Also effectively already dead are the Resident Orca. They are living on borrowed time. Like a chicken with its head removed and the legs keep kicking. And somehow, while the west coast are still busy killing the Orca... we're expecting Africa, Asia, and South America to do BETTER than the US/Canada? I call BS. If fre**ing Oregon is overpopulated enough to drive Grizzlies and Orcas to extinction, you can consider all megafauna the world over on borrowed time as well. Am I saying this to rub salt in the wound? No, it is killing me. And this is one example of literally millions of species that our urbanization and sub-urbanization has made non-endemic, limited only to 'reservations' a few acres across. "Well its true my neighborhood used to house deer, foxes, wolves and bears, and now its a row of townhouses, but I drive a Hybrid!!!! So I'm literally saving the planet". Carbon is a proxy argument for ecological damage. Our presence is what is devastating. Hybirds are the solution to the proxy argument... which they can SELL you while you think of yourself as not doing damage, when in reality you are. But no more than the other 8 billion presences on the planet. The argument of overpopulation should not be about 'how many more people can we cram into this space and feed / remove the sh** they produce on a weekly basis'. It should be about the fact that we are headed at blinding speed towards a world of humans, cockroaches, pigeons and city rats. This will happen 1000s of years before 'OMGCarbon' Ironically, if Washington, Oregon, British Columbia and N. California could learn to burn some oil... they could feasibly save the fish, orcas, and bears. "Mr. Inslee...

Deforestation of the Amazon has nothing to do with population growth/density but it is all to do with money and greed! Just want to add some more info on this that is quite staggering IMO "The Amazon rainforest basin covers approximately seven million square kilometers (1.7 billion acres)(5,500,000 square kilometers)(5) there are about 49,422 trees per square kilometer in the Amazon(6). Each tree out of the 49,422 trees per square kilometer produces about 260 pounds a year, enough for a family of four, but not all trees produce the same exact amount of oxygen each year. (7)Therefore every square kilometers of trees produce 12,849,720 pounds of oxygen each year. In every square kilometer there are 247.105 acres (8) this means there are about 200 trees per acre in the Amazon rainforest. So per acre in the Amazon rainforest 52,000 pounds of oxygen is produced every year. In the entire Amazon rainforest there are 13,590,775,00 acres. This means in the whole Amazon rainforest there are about 271, 821,000,000 trees! Can you then believe 7,067,346e13= 7,067,446,000,000,0 pounds of oxygen is produced every year in the Amazon rainforest. To show how big this value is I will put it in to perspective and compare it to the famous central park. Central park covers approximately 3.41 square kilometers.(9) If central park would also have 49,422 trees per square kilometer it would approximately have in its entire park, 168,529 trees. Central park has about 84,2628 acres. This will mean every acre has about 682 trees. So every acre produces a total amount of 17,732,0 pounds of oxygen each year. Each square kilometer produces 88,660 pounds of oxygen each year, and the entire central park produces 219,083,280 pounds of oxygen each year. This all means it would take central park 322591 years to make as much oxygen as the Amazon makes each year!" Quote Share this post Link to post Share on other sites

I think that all people could be better served by better urban and rural planning with preferred options for all. Greenbelts, agricultural zoning, one half to five acre subdivisions etc. Eight homes to an acre is the approximate minimum now and for me that is too close.
