At least 155 states recognize their citizens have the right to live in a healthy environment, either through national legislation or international accords, like the Universal Declaration of Human Rights.
Despite those protections, the World Health Organization estimates that 23 per cent of all deaths are linked to “environmental risks” like air pollution, water contamination and chemical exposure.
Statistics like that are why the United Nations Human Rights Council recently passed a resolution reaffirming states’ obligations to protect human rights, including by taking stronger actions on environmental challenges.
Here are some of the ways that a compromised planet is now compromising the human right to health.
1. The destruction of wild spaces facilitates the emergence of zoonotic diseases.
The alteration of land to create space for homes, farms and industries has put humans in increasing contact with wildlife and has created opportunities for pathogens to spill over from wild animals to people.
An estimated 60 per cent of human infections are of animal origin. And there are plenty of other viruses poised to jump from animals to humans. According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, “as many as 1.7 million unidentified viruses of the type known to infect people are believed to still exist in mammals and waterfowl. Any one of these could be the next ‘Disease X’ – potentially even more disruptive and lethal than COVID-19.”
2. Air pollution reduces quality of health and lowers life expectancy.
Across the globe, nine in 10 people are breathing unclean air, harming their health and shortening their life span. Every year, about 7 million people die from diseases and infections related to air pollution, more than five times the number of people who perish in road traffic collisions.
Exposure to pollutants can also affect the brain, causing developmental delays, behavioural problems and even lower IQs in children. In older people, pollutants are associated with Alzheimer’s and Parkinson’s diseases.
3. Biodiversity loss compromises the nutritional value of food.
In the last 50 years alone, human diets have become 37 per cent more similar, with just 12 crops and five animal species providing 75 per cent of the world’s energy intake. Today, nearly one in three people suffer from some form of malnutrition and much of the world’s population is affected by diet-related diseases, such as heart disease, diabetes and cancer. Read more…
