With all this hunkering down and less physical activity I am guessing that the U.S. population is going to gain 18lbs./per capita over the long haul.
That's 328,953,020 X 18 = 5,921,154,360 lbs. extra.
The additional weight that NYC will gain could sink that city into the Hudson River. California could slide into the Pacific and the Gulf of Mexico could put New Orleans under 20' of water.
