The death of Cecil the lion has caused global public outrage, the like of which has never been seen before.

We need to act to stop uncontrolled shark fishing now; adopting effective management before crisis recovery plans are needed. The high seas can no longer be an out of sight out of mind wild frontier where anything goes. We could lose sharks from our seas within my lifetime, and that simply must not happen. Lose the sharks, the mighty, mysterious lords of the deep, and our planet's oceans would be infinitely poorer places.
These two meetings are the culmination of long, intensive processes, and present governments across the world with the chance to make bold decisions. If they rise to the challenge, they can set us all on a path to address the inter-connected crises of poverty, inequality, environmental degradation and climate change.
Visiting Kenya last weekend, Barack Obama stirred hearts and minds with his words on the country's potential to become a development success story. Gracing a summit on African entrepreneurship, the President rightly celebrates the efforts of the inspirational men and women working to bring prosperity to the country and the wider continent.
The island of Madagascar plays host to an exciting array of rare wildlife and is home to mesmerising landscape. Its natural beauty is a one off and so is its story of existence.
