We must turn the greatest collective challenge facing humankind today – climate change – into the greatest opportunity for common progress towards a sustainable future.

Climate change, demographics, water, food, energy, global health, women's empowerment - these issues are all intertwined. We cannot look at one strand in isolation. Instead, we must examine how these strands are woven together.

The world is over-armed and peace is under-funded.

We have all heard of the web of life. The way we live threatens to trap us in a web of death.

The basic building block of peace and security for all peoples is economic and social security, anchored in sustainable development. It is a key to all problems. Why? Because it allows us to address all the great issues-poverty, climate, environment and political stability-as parts of the whole.
