Of course I have to start with the most likely candidate: WWF, the World Wildlife Fund originally, but now it actually stands for World Wide Fund For Nature. The Dutch will know it as WNF; Wereld Natuur Fonds. Our late Prince Bernhard was one of the eminent gentlemen who started the whole thing. WWF has the infamous panda logo. Which makes it cheap to print in full colour: you only need black ink ;-)
Let's quote some of the history:
"WWF was born into this world in 1961.
It was the product of a deep concern held by a few eminent gentlemen who were worried by what they saw happening in our world at that time.
Since those early days WWF has grown up to be one of the largest environmental organizations in the world.
Currently there are more than 1300 WWF conservation projects underway around the world.
The vast majority of these focus on local issues. They range from school nature gardens in Zambia, to initiatives that appear on the packaging in your local supermarket. From the restoration of orangutan habitats to the establishment of giant panda reserves.
Almost all our work involves partnerships.
We team up with local non-profit agencies and other global NGOs. We form relationships with village elders, local councils and regional government offices. And in this day and age of globalization, critically, we work with businesses who are willing to change."
I don't think I need to go to great lengths to introduce the organisation. More interesting perhaps what and where to follow? They've got their social media up to par. WWF practically uses anything out there. That means they follow the right strategy! So they hired the proper guy or gal (Note: in November 2007 I applied for the role of Online Community Specialist with WWF / IUCN in Gland, Switserland, did not pass unfortunately. But apparently they have a capable person as well for the job :P ).

They even have their own group (discussions!) on LinkedIn, but I don't participate in that: http://www.linkedin.com/groups/WWF-44458
For those who are into it (not me), even videos on Vimeo and sharing links and reviews on StumbleUpon.
Most stuff of WWF I come across is via Facebook. They really have tons of materials. And also alert you of petitions to sign for some relevant projects. Can't get it any easier.
