• 24 per cent of our galaxy’s elemental mass consists of helium • Because of its lightness, helium vanished from our own planet

Слайд 1PROBLEM, THAT IS SILENT BY EVERYONE
Helium itself is not rare; there

is actually a plentiful supply of it in the cosmos. In

fact, 24 per cent of our galaxy’s elemental mass consists of helium, which makes it the

second most abundant element in our universe. Because of its lightness, however, most

helium vanished from our own planet many years ago. Consequently, only a miniscule

proportion – 0.00052%, to be exact – remains in earth’s atmosphere. Helium is the by-

product of millennia of radioactive decay from the elements thorium and uranium. The

helium is mostly trapped in subterranean natural gas bunkers and commercially

extracted through a me

thod known as fracti

onal distillation

"the government had the good vision to store helium, and the

question now is: Will the corporations have the vision to capture it when extracting natural gas, and consumers the wisdom to recycle? This takes long-term vision because present market forces are not sufficient to compel prudent practice”
