Climate change also threatens our food system which must produce 50% more food to feed over 9 billion people by 2050. However, changing weather patterns and growing seasons threaten suitable cultivation areas around the world. Business can spur positive change and achieving food security could create 80 million jobs and business opportunities worth $2.3 trillion annually by 2030. Linked to climate change is water scarcity, a threat to 3.2 billion people. If current usage continues the world will have only 60% of its required water by 2030. See pages 30 and 33 to 35 for more on climate change risks.
