> Pri vsem tem pisanju o miljardah ali biljardah na novo zasajenih dreves pa nihče ne omeni, da je naša zemlja po raziskavah NSA vse bolj zeleni planet,

Za Slovenijo to vsekakor velja (govora je bilo namreč o tem, koliko dreves je potrebno posaditi). V Valvazorjevih časih je bilo pogozdeno cca 25% slovenskega ozemlja, sedaj preko 50%. Slovenija ima cca 300 mio m3 zalog lesne mase, vsako leto pa je neto prirastek cca 4 mio m3 (prirast nekje v rangu 7-9 mio, posek pa v rangu 4 mio).

Ne gre toliko za sajenje drevja, kakor za bolj bujno rast kot posledica večje koncentracije CO2 (in tudi N2) v atmosferi. Citiram:

Results showed that carbon dioxide fertilization explains 70 percent of the greening effect, said co-author Ranga Myneni, a professor in the Department of Earth and Environment at Boston University. “The second most important driver is nitrogen, at 9 percent. So we see what an outsized role CO2 plays in this process.”

In še to:

About 85 percent of Earth’s ice-free lands is covered by vegetation. The area covered by all the green leaves on Earth is equal to, on average, 32 percent of Earth’s total surface area - oceans, lands and permanent ice sheets combined. The extent of the greening over the past 35 years “has the ability to fundamentally change the cycling of water and carbon in the climate system,” said lead author Zaichun Zhu, a researcher from Peking University, China, who did the first half of this study with Myneni as a visiting scholar at Boston University.

Pa še malce zlobna opomba na:

Naj si vsak sam izračuna, kakšno hranilno vrednost ima ta les.

Les kot hranilo se bolj malo uporablja, kakšne koze objedajo malde veje, nekaj divjad, v restavraciji mi pa še niso nikjer servirali popečeno bukovo (ali katero koli drugo) poleno namesto krače.
