Air Pollution Is Killing Millions and Rising Exponentially--A Shift in Agriculture Can Solve It

In 1958, geochemist Charles David Keeling set up the Mauna Loa Global Monitoring Laboratory in Hawaii, which measured carbon dioxide (CO2). Keeling believed that CO2 levels were rising and wanted to prove it. Mauna Loa was a perfect location to obtain precise readings since it was located at an elevation of more than 13,000 feet in the middle of the Pacific Ocean. By 1959, the level of CO2 was 316 parts per million volume (ppmV). Since then, the curve has seen an exponential rise. As of May 2024, the amount of CO2 in the atmosphere had risen to more than 426 ppmV.

It has been more than 4 million years since CO2 levels were as high as today. “[The] CO2 levels are now comparable to the Pliocene Climatic Optimum, between 4.1 and 4.5 million years ago, when they were close to, or above 400 ppm. During that time, sea levels were between 5 and 25 meters higher than today, high enough to drown many of the world’s largest modern cities,” stated a report by the National Oceanic and Atmospheric Administration.

These pollution levels are undoubtedly human-caused and have primarily resulted from burning fossil fuels, deforestation, and land-use change by industrial agriculture. In designing our society from an anthropocentric point of view (prioritizing humans above all other species), we have not only neglected but also harmed the Earth’s natural systems. To maintain a sustainable environment, we must adopt an eco-centric point of view that prioritizes the intrinsic value of all living things and preserves the ecological balance.

The Perfect Balance

Carbon dioxide gives our planet life. All living plants need it, converting it into an energy source. They assimilate carbon and expel the oxygen that all faunal beings require. When humans and animals breathe in oxygen, they exhale carbon dioxide, a greenhouse gas (GHG) that traps heat. Other gases that heat the atmosphere include methane (CH4) and nitrous oxide (N2O).
