Drip system at every plant with chemical fertilizers Agreed However the cost on a large acreage would be astronomical and for what payback?? A very small impact on Co2. 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! 3 2 Quote Share this post Link to post Share on other sites

She should focus some of her efforts here as I don't think anyone can argue its a good idea to destroy rain forests at this rate, I might have a lot more respect for her if she did.

You are of course rigth, but my understanding is that it stopping existing deforesting would tackle the issue alone. That's why a cost analysis would be interesting. The Sahara is basically unused land that doesn't really do any good (atleast that I know of). I have read scientic articles about mining the moon in order to get material for fusion, but I cannot find any info a project that would basically just be using existing technology. 1 Quote Share this post Link to post Share on other sites

A few examples 1) Less meat in our diets is not only good for the enviroment, it is also good for our health 2) Demanding that China tackles pollution or the entire civilized world puts tariffs on them. Demand that they live up to Western enviromental manufacturing standards (EU ones as they are way stricter than American) or they cannot trade with us. Demand that they put plastic collection nets at their or they cannot trade with us.. etc. Above would like be good the West as well. But obviously it requires hardcore fossil fuel crusaders to have a balanced view, so much more likely to talk about mining the moon...

That's because no project would be economically viable in the Sahara Rasmus. No privately owned company is going to just throw money and resource on a project they know will have no return on investment. For that matter no government should either unless there are significant other benefits to their people. There is no African country rich enough to fund such a project. The Sahara is growing see attached https://www.livescience.com/62168-sahara-desert-expanding.html If we stop the deforestation in the Amazon then this should help with a slowdown on desertification elsewhere ie Sahara I don't understand why we would tackle an extremely difficult issue of irrigating the Sahara (which may cause other environmental issues as Enthalpic suggested, such as all the fauna that would live in the rain forest that aren't natural to the area) when we can instantly save 78 million acres of rain forest in the first year?? No pun intended but lets start on the low hanging fruit (easy wins) first. I remind you 78 million acres!! I'd be very interested if any boffins out there could estimate a rough cost to irrigate 78 million acres of the Sahara via hydroponics. I think the cost would be mind boggling!

I accept that. But this is based on the premis that the climate change is not caused by CO2 and there is no cost to an AGW scenario. If even a fraction of some of the projections are accurate then an AGW scenario would be very expensive the world. Not speaking an opinion on the topic, just slightly worried. And I need to stress again - if even a fraction of some of the projections are accurate then an AGW scenario would be very expensive the world. far more expensive than irrigating the sahara. low hanging fruits first, of course (life style changes in the west, stabilize the amazon etc)... but is that enough ?

About 2 years ago though we started eating less meat, but better quality locally produced. And local produce as well. Not religiously, but generally we try to teach the kids to purchase locally for their health and the health of the planet I consider myself an eco-pragmatist and as such I don't agree 100 % with the Greta Thunberg message, but I think she (or those guiding her) are more right than wrong.

Exactly. If you do a 2x2 risk assessment doing something becomes the obvious decision. It is real, and we do something = expensive but we saved the planet. It is fake, and we do something = expensive but we probably come out better-off anyways (less "real" pollution). It is real, and we ignore it = death and destruction.

I have never seen cost analysis on this, but I actually think it would be favourable. I would be interesting though what that would do to the worlds weather system. Of course, the people who depend on the rivers, in their present channels, won’t be annoyed in the slightest when you redirect the rivers to ‘turn the Sahara into a rain-forest’. I have serious doubts, due to lack of topsoil, that any amount of water would reverse the course of desertification.

It baffles me; big oil could do so much at relatively little cost and in return gain much public support. Flaring (or even worse, venting) of NG because oversupply of gas has driven the price so low. 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. 1 4 Quote Share this post Link to post Share on other sites
