IUCN and IUCN Redlist

The «Inter­na­tional Union­for Conser­va­tion of Nature and Nat­ural Resources» is an organ­i­sa­tion, ded­i­cated to the con­ser­va­tion of global bio­di­ver­sity. Other key phrases, men­tioned on their home page are cli­mate change, sus­tain­able energy, human well being or green econ­omy. It was founded in 1948 and has grown to become a col­lec­tive of more than a thou­sand mem­ber organ­i­sa­tions.
States, Gov­ern­ment Agen­cies and dif­fer­ent organ­i­sa­tions are being offered mem­ber­ship. Indi­vid­u­als can apply to become a mem­ber of the six IUCN Com­mis­sions.
The IUCN is quite well known for its «Red List of Threat­ened Species».

Palm Oil

To us it seems quite evi­dent that the increas­ing palm oil pro­duc­tion is at least par­tially respon­si­ble for the ongo­ing destruc­tion of the peat swamp forests in South East Asia.
Of course there are numer­ous pro and con­tra opin­ions posted all over the inter­net.
Here is a selec­tion of four, infor­ma­tive and/​or more crit­i­cal ones:

Wet­lands International

Wet­lands Inter­na­tional is non profit organ­i­sa­tion with head­quar­ters in the Nether­lands and bureaus in sev­eral coun­tries. It is ded­i­cated to the con­ser­va­tion and restau­ra­tion of the world’s wet­lands, marches, peat swamps for sus­tain­able use by the local peo­ple, keep­ing the bio­di­ver­sity.
The inter­na­tional home­page is in Eng­lish but the pages focussing on national or regional aspects are par­tially in respec­tive lan­guages — French, Span­ish.
I’m not quite sure what to think of Shell Oil being a part­ner orga­ni­za­tion but anyway.

Borneo’s defor­esta­tion

There is a map show­ing the defor­esta­tion on Bor­neo since 1950.
Admit­ted that it is dif­fi­cult to say wether this is a legit­i­mate illus­ta­tion based on facts — It appears prob­a­ble, at least based on the inor­ma­tion given by Wikipedia (http://​en​.wikipedia​.org/​w​i​k​i​/​D​e​f​o​r​e​s​t​a​t​i​o​n​_​i​n​_​I​n​d​o​n​e​s​i​a).
