GrowthBusters: Hooked on Growth  (film)

This film examines the cultural barriers that prevent us from reacting rationally to the evidence current levels of population and consumption are unsustainable. It asks why the population conversations are so difficult to have. Why it’s more important to our society to have economic growth than clean air. Why communities seek and subsidize growth even when it destroys quality of life and increases taxes. Our growth-centric system is broken. It’s not providing the happiness or the prosperity we seek. But that’s good news; it means a shift to a sustainable model will be good for us. We’ll be happier and more prosperous!

International Anti-Poaching Foundation – (international)

The illegal trafficking of wildlife is now one of the world’s largest criminal industries, with repeated links to terrorism networks. High Target Species such as elephant and rhino are being hunted to extinction. These animals are the most difficult to protect, as poachers go to the most extreme lengths to kill them. If we can safeguard these animals, then entire ecosystems are protected. Anti-poaching rangers form the first and last line of defense for nature. Without the right training, equipment, management and support they cannot defend the World’s natural heritage for future generations. The IAPF fulfills this niche responsibility within its areas of operations, whilst working alongside credible partners who specialize in the other vital components of conserving protected area biodiversity.
