Earth has more trees than it did 35 years ago - but there’s a huge catch

However, an important distinction needs to be made between tree cover and forest cover.
The study points out that industrial timber plantations, mature oil palm estates and other specifically planted forests add to global tree cover. On paper these areas compensate for the primary forest that has been cut down; 100-hectare loss of primary forest is perfectly offset by a 100-hectare gain on a man-made plantation, for example.
But while they may be equal in area, they are not equal in biodiversity. Primary tropical forests and savannas harbour a wealth of flora and fauna which is lost when these areas are cleared.

Last week we were treated to an explanation of why the smallest recorded hole in the ozone near the South Pole was no big deal and "probably" didn't have anything to do with human efforts to limit pollution but was "probably" the result of "freakish weather" . I thought that was a funny one. An entire movement based off of repeated references to a growing hole in the ozone layer and when it has shrunk and is the smallest ever recorded it seems to mean nothing. Hilarious. Billion dollar bullshit.

The 1987 international Montreal Protocol — the only United Nations treaty ratified by every country on Earth — banned many of the chlorine compounds used in refrigerants and aerosols. The ban resulted in a slightly smaller ozone hole in recent years, but this year's dramatic shrinking isn't from those efforts, Newman said.
