The theme of World Health Day 2022

On this World Health Day, WHO decided to focus on urgent actions required to keep the earth and human beings healthy. The theme of World Health Day 2022 is Our planet, our health. According to WHO estimate, more than 13 million deaths across the globe were a result of environmental problems, including the climate crisis. As of now, the climate crisis is one of the biggest threats to humanity. These environmental problems are avoidable as well as controllable. Given this, WHO, through this year’s World Health Day theme, aims to create and encourage the members of global societies to be more focused on overall health.  

Given below are some of the reasons why WHO focused on planet and human health for the World Health Day 2022 theme [1]:

  • Excess burning of fossil fuels has now resulted in over 90% of the population breathing unhealthy air.
  • Water scarcity, extreme weather conditions, and land degradation is displacing people all over the world, yielding an adverse effect on their health.
  • Pollutants at the bottom of mountains and oceans not only affect animal life but have also become a part of our food.
  • Rising temperatures have resulted in a quicker and farther spread of diseases through mosquitoes.
  • Manufacturers of processed and unhealthy food and drinks generate nearly one-third of greenhouse gas emissions across the globe. Production of these foods and drinks has also increased the number of people who are overweight or obese. This, in turn, affects the health and causes heart conditions, stomach problems, and more diseases.

The COVID pandemic shed light on science as well as nature’s power of healing. But it also highlighted where society lacks by showing the inequities in our social structure. And while nature can heal itself, the COVID-19 pandemic made society aware of the urgent need to create a better society for humans as well as the planet. There is a need for a society that is committed to sustainability while working towards improving overall health. Read on to find out nine facts about World Health Day.
