Ummm... it’s in the water. So how does drilling cause “ground surface collapse”?
What a dip-wad! (the author)
Sometimes peoples leg-bone just ain’t connected to their brain-bone!
The author might have written it better. But the ground, (Ocean Floor), has more of a chance of collapsing with the weight of the water on top as the Hydrates are removed.
Which has its own measure of risk, imagine a Methane Ice breakthrough rising to the surface of the surrounding water. The potential there for methane poisoning of the water is pretty high and the release of the sublimating ‘ice’ into methane gas into the atmosphere is there too.
Once all of these risks and potential hazards are worked around there is a lot of energy available as well as ‘feed-stock’ for various industries that can use it to produce other goods and materials.
Not to mention the old "fuel bomb" effect.
