Can someone tell me what percentage of the earth’s population resides on ocean coastlines? I thought it was something like 70 percent, but I could have confused that stat with the amount of water that covers the earth. Or how much of the human body is comprised of water. Or what percentage of the work day I am actually productive.
If you have a cite to support your information, it is appreciated. If you have a link to a website that provides such and similar geographical data, it is also very much appreciated.
I am seeking evidential support for the notion that converting the movement of the ocean waves into electricity would be beneficial to the masses.
However, 400 km is a pretty deep measure of “coastal.” It would probably correctly identify most of Bangaldesh as coastal, but would be a serious overstatement for the U.S. East Coast, extending far past the Piedmont, and would be a gross exaggeration on the West Coast, as well. (A rise of the oceans as measured in meters would drown a lot of agricultural land in California as well as most of Puget Sound, wreaking economic havoc on those regions (and the U.S.), yet would have little to no direct impact on the survivability of cities located in the hills above the Pacific Coast.)
