Global warming's consequences are hastening the global decline in air quality, which is endangering human health and the ecosystem. Around 7 million people worldwide die prematurely each year as a result of indoor and outdoor air pollution, according to the World Health Organization, which estimates that 99% of the world's population breaths filthy air.
For both our continued existence on the earth and the effort to stop the climate problem, trees are essential.In addition to lowering temperatures, preserving the health of the soil, and assisting in the maintenance of animal life, they also remove billions of tonnes of carbon dioxide from the atmosphere.
According to the UN, air pollution is a transboundary problem that calls for coordinated action from local, national, regional, and international stakeholders. In order to effectively tackle air pollution, it exhorts governments, businesses, civil society, and individuals to work together across boundaries and sectors.
Through the process of photosynthesis, forests are vital in removing carbon dioxide from the atmosphere. In addition to absorbing carbon dioxide, which is the main greenhouse gas contributing to climate change, trees also emit oxygen, which is necessary for human living. This natural carbon sequestration contributes to healthier environments and cleaner air by reducing the negative consequences of air pollution.
However, with around 10 million hectares (100,000 km2) of forest lost each year globally, deforestation continues to be a serious problem. In an effort to restore biodiversity and combat climate change, the World Economic Forum launched a global campaign in 2020 to grow, repair, and save 1 trillion trees worldwide. The 1t.org project intends to bring together companies, non-profits, governments, and individuals in a "mass-scale nature restoration".
The most recent Air Quality Life Index (AQLI) yearly update provides sobering statistics on the health risks associated with air pollution. It poses the biggest hazard to human health, potentially decreasing the average person's life span by 2.3 years and having a similar effect on life expectancy to smoking.
