Light Pollution
Soaring energy costs and changing work patterns due to the pandemic have resulted in a drop in the amount of light polluting the night sky, at least in Britain.
The Guardian reports that a survey by the rural charity CPRE found that amateur stargazers have for the past two years been enjoying better views of the heavens.
It points to homes and local agencies switching off DUWLÀFLDO OLJKWV GXH WR KLJK power bills, and businesses not turning on as many lights because employees are working from home.
CPRE advocates for legal protection of the night sky, asking local agencies to place streetlights where they won’t cause needless pollution, harming wildlife.

Rare and Red
Panamanian researchers say they have discovered a dazzling red salamander in one of the country’s cloud forests that is new to science.
The amphibian was GXEEHG WKH &KLULTXt ÀUH VDOamander (Bolitoglossa cathyledecae) after it was found in La Amistad International Park, which Panama shares with Costa Rica. Its Talamanca mountain range is one of the least-explored regions of Central America.
Writing in the journal Zootaxa, the researchers say it is different from other members of its genus because of its color, webbed feet and large number of upper teeth. The salamander lives in a very small high-altitude habitat in the park. 'LVW E\ $QGUHZV 0F0HHO 6\QGLFDWLRQ 00;;,, (DUWK (QYLURQPHQW 6HUYLFH

Pollution Kills
Approximately 1 in 10 premature deaths worldwide during 2019 were linked to pollution, according to a new report by the Lancet Commission.
It says 9 million people died during the year due to breathing toxic outside air and from lead poisoning.
Pollution is an “existential threat to human health and planetary health, and jeopardizes the sustainability of modern societies,” the report concludes.
While pollution rarely kills immediately, it does trigger heart disease, cancer, respiratory problems, diarrhea and other serious illnesses, according to the report.
