Answer:
After being hunted almost to extinction, the humpback whale population has rebounded dramatically. Rapidly melting Antarctica ice poses a threat to coastal cities, but there is at least one species that is benefiting: Humpback whales are flourishing these days, due to an abundance of krill.
Pre-hunting population size may have been as many as 200,000-300,000 whales. They were estimated to number around 2,300 in 1998 and to be increasing between 2.4-8.4% per year. The IWC is undertaking an assessment of Antarctic blue whales at present.
The answer is fluorite. If a mineral cannot be scratched by a knife blade but can be scratched by quartz then its hardness is between 5 and 7 on mohs scale. A relative hardness value of 6.5 means that the mineral could scratch orthoclase but not quartz. Flourite hardness on mohs scale is 4, and therefore due to the very low hardness and perfect cleavage of Flourite, special care must be taken to ensure it doesn't get scratched or chipped. It cannot scratch the glass.
