The United Nations says the world needs a new way of thinking about environmental crises threatening the health of people and the planet. The scientists in the new report say climate change, biodiversity loss, land degradation and pollution should be addressed at the same time because each affects the others. They also affect the economy, human health, food and water security and even national security. The U.N. Environment Programme’s outlook was released Tuesday during the U.N. Environment Assembly in Kenya.
