Helium - If it's used in TV screens, it's not gone. So there's no shortage being created. It's an inert gas. It does not react with other chemicals, so that does not cause it's quantities to decrease. If it escapes from our helium balloons where does it go? The upper atmosphere. Also - not gone. Helium is not escaping into space. Conclusion - we're not running out. We're simply using it more now and faster than we can find it in our relatively closed world system.
Sardines - Wait, did he say cooling oceans? Global cooling in progress? And as far as over-fishing, well global populations are cyclical;
In 1948, this question was posed to ocean biologist Ed Rickett, who was investigating the most famous sardine crash in history, which began in 1946. He responded, “They’re in cans!” Today’s scientists don’t think the answer is so simple, as sardine populations are known for following a boom-and-bust cycle. However, they don’t deny that rampant fishing played a significant role in the mid-century crash, and have found that cool water temperatures triggered a natural decline in the 1940s, which was greatly exacerbated by overfishing. It would take four decades for the population to recover from that crash.By the late 1980s, sardines had enjoyed a spectacular comeback. For two decades, populations remained sta
