• Climate change is expected to cause approximately 250,000 additional deaths per year between 2030 and 2050 due to heat stress, diarrhoea, malaria, and childhood undernutrition.

• Globally, 76% of the population derives most of their daily protein from plants. If CO2 levels continue to rise as projected, researchers estimate that roughly an additional 150 million people may be placed at risk of protein deficiency because of elevated levels of CO2 in the atmosphere.

• Changes to diet paterns — both, levels of consumption and composition — imply that the “triple burden” of undernourishment, over-nourishment and malnutrition will persist in developing countries.

• Some 815 million people suffered of hunger in 2016 (11% of the global population) — an increase of 38 million compared to 2015. The rates of other forms of malnutrition such as nutrient deficiency and obesity are also alarmingly high. Over 2 billion people suffer from micronutrient deficiencies, while 1.9 billion adults and 41 million children are overweight.

• Air pollution:
  • Since 2010, buildings-related CO2 emissions have continued to rise by around 1% per year globally. Over 4 million deaths per year are attributable to illness from household air pollution.
  • Some 85% of the urban population in the EU is being exposed to fine particulate matter (PM2.5) at levels deemed harmful to health.
  • Bangalore, India's Silicon Valley might become “unliveable” in a few years. Unsustainable rapid urbanisation caused a decline of 88% in the city’s vegetation between 1973 and 2016, while water bodies declined by 85% between 2000 and 2014. If present trends continue, over the next three years, the built up area in Bangalore is expected to increase from 77% to 93%, with a vegetation cover of a mere 3%. The city's e-waste is estimated at 20,000 tonnes per year. Respiratory and other health problems have increased drastically in the city recently. | Related Megatrends: Urbanisation; Geopower; Inequalities
• Noise might become the next great public health threat given that by 2100, some 84% of the world's population will live in cities, surrounded by a cloud of various sounds.
