How do you propose to get rid of billions of extra folks? You haven't shown any evidence that the CO2 in the atmosphere is the reason we can support more people today. By your argument all of our technological advancements have nothing to do with it. Apparently all we needed to do was set all the coal and oil fields on fire to up the co2 levels and suddenly we would be able to feed another 7 billion people. Daft.

The evidence was in the post I gave you earlier that higher levels of CO2 cause a greening of the plant biosphere, which is what we would expect. You cannot sustain human life with better medical equipment, while depriving people of oxygen and food. Some items are more basic than others.

That's too simplistic way of thinking.

All it takes is the right strategic bets in technology. These days, things like famines tend to happen because of local political instability, not because people don't know how to grow enough food.

A higher CO2 supply would just promote plant macronutrient growth in stuff we don't need and create climate stress in areas of the world where are malnourished people (that rely on for example, the monsoons in Africa and South Asia).

Jay McKinsey + 1,490 April 29, 2021 And just to make sure this is clear, the EIA includes hydro in their definition of renewable energy. I accept all of your apologies. What is renewable energy? Renewable energy is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time. The major types of renewable energy sources are Biomass Wood and wood waste Municipal solid waste Landfill gas and biogas Ethanol Biodiesel Hydropower Geothermal Wind Solar https://www.eia.gov/energyexplained/renewable-sources/ 1 Quote Share this post Link to post Share on other sites

No, even cattle and chickens require plant life to eat, if you reduce the food stocks of livestock you have the same constraints from a different angle. If you reduce CO2 in the atmosphere going forward agricultural productivity declines, that is a given. That translates into less plant life, less grains and vegetables, less oxygen to breathe, bad news all around. 1 Quote Share this post Link to post Share on other sites

It depends on technology adoption. https://www.iea.org/commentaries/going-carbon-negative-what-are-the-technology-options The expenditure involved in such an endeavor is far beyond the worth. Real polluton is the real problem not CO2. There are many problems that require money that would be a higher priority. Maximizing use of natural gas and biogas while reducing coal use would be better choice. Build wind turbines too, but only in the proportion that makes sense and is cost effective. 2 Quote Share this post Link to post Share on other sites

Meredith Poor + 893 MP April 29, 2021 11 hours ago, JoMack said: This photo is apparently the Midway Wind farm. From the ground, no pumpjacks, no Christmas trees. So, no oil and gas. A zoomed in shot at Midway. One wind turbine with a tiny bit of 'disturbed earth' and three hydrocarbon extraction points, two of which have the 3 tank configuration for separating water from oil. The third one may be a DUC. The original screen capture shows a lot more well pads. I suspect that the picture you've included obscures all this stuff due to the soybeans growing in the fields. 1 Quote Share this post Link to post Share on other sites

The idea of lab grown meat disgusts me, and many others. I would go vegetarian first. As it is, I have eaten less meat al I have grown older. I use meat more as a flavoring for soups, stews, chili etc. I like the way Asians eat it with lots of rice, legumes, spices, and vegetables. 1 Quote Share this post Link to post Share on other sites

turbguy + 1,518 April 29, 2021 3 hours ago, ronwagn said: Why is it that wind tyurbine blades and motors are not replaced then? They are cut up and buried in Mother Earth, not made into metal. Turbines are rebuilt and most parts stay as original. The metal is reused because it is recyclable. When a CT's first stage blades/buckets are replaced, you better hold onto your wallet. When a steam turbine ROTOR is replaced, you better hold onto your wallet. When a large generator is rewound/re-insulated, you better hold onto your wallet. Similar to wind turbines, I would suppose. Geared wind turbines can be particularly troublesome... Anything with moving parts is gonna have future costs. Solar panels? Not sure... 1 Quote Share this post Link to post Share on other sites
