#456 Inside a Conservation NGO
This week we take a close look at conservation NGOS: what they do, how they work, and - most importantly - why we need them. We'll be speaking with Shyla Raghav, the Climate Change Lead at Conservation International, about using strategy and policy to tackle climate change. Then we'll speak with Rebecca Shaw, Lead Scientist at the World Wildlife Fund, about how and why you should get involved with conservation initiatives.
