Some of those lakes that are dealing with large environmental issues embody Utah’s Great Salt Lake, Asia’s Aral Sea, the Dead Sea in Jordan and Israel, Lop Nur in China, and Lake Popo in Bolivia.
A gaggle of scientists and water managers in Utah and Montana had warned that these saline lakes are in hassle.
Why ought to the warning be worrisome? Here are a few of the the explanation why.
Saline lakes play an essential position in wildlife, business, and human well being. Migratory birds discover their dwelling close to saline lakes.

In a research printed within the journal Geoscience, the authors tied the shrinking of the salt lakes to the results of water use and local weather change.

Losing as a lot as 50 p.c of its space, this results in the displacement of migratory birds that used to nests and feed within the lake.
The decline had additionally uncovered the lake to mud storms as a result of uncovered lakebed.
“The Great Salt Lake is definitely shrinking,” research’s lead writer Wurtsbaugh stated.
“Although the lake had risen and fallen with droughts and floods in recent decades, the persistence of water diversions has decreased the lake’s level,” he stated.
The state, in line with the researchers, should not solely plan how one can proceed creating water from the lake however should plan to herald further water assets again to the lake to revive the lake to its wholesome life.
