No. In fact, I don't know why David Hammen didn't say that instead of commenting. The deepest hole that mankind ever dug was barely a scratch on the Earth's surface when you look at its size. They didn't even reach the mantle. The hole is only 12km deep, took about 20 years to create, and is still only 1/3 of the way to the mantle! Also, the hole is nothing ...

One of the flaws with using subduction zones as dumps for toxic chemicals so they can be broken down by heat and pressure at depth is the rate of sinking of the subducting plate. Subduction is a very slow process, generally between 2 and 8 centimeters per year. Any toxic material is going to hang around the interface for a very long time, with the potential ...

Specifically regarding the table in your question, the last column compares the emissions not by mass but by CO2-Eqivalent mass. That means that the number already takes into account that the global warming potential of N2O is much higher, so every emitted molecule of N2O counts like 298 molecules of CO2. In other words, when the table says 7.9% is N2O, it ...

Where am I wrong in my assumption about natural water distillation (i.e. is rain water not as clean as it should be in theory)? Generally, rain water is pretty clean. That is not an issue. Plus, we treat ground water and reservoir/lake/river water, so we could easily treat rain water. What you really fail to miss is that ground water and reservoir/lake/...

I guess it depends on which biome classification you use (there are several), but yes, usually tropical forests of Amazonia, Africa & Asia are classified within the same biome. For instance if you take the WWF classification made by Olson et al. (2001), which has 14 terrestrial biomes, they all fall in the "Tropical and subtropical moist broadleaf ...

Agricultural water is largely Fossil Water, which took tens of thousands of years to accumulate and industrial activities have used it in a century. Saudi Arabia is abandoning programs to grow wheat that achieved self-sufficiency but depleted the desert kingdom's scarce water supplies. Going from the 6th largest exporter to NO more. Humanity derives water ...
