Amusing. Fairly substantial for the less-informed. Facts (claims?) I can use are on page 104 of the large print edition:
- The Macy's parade balloons use almost as much helium as the US military
- 21 billion m3 in the helium reserve in 2017, 31 billion m3 worldwide
- 47 million m3/year in the US
- Big bang cosmology, no more than 1% lithium, no less than 10% helium
