Air Pollution Is Killing Millions and Rising Exponentially—A Shift in Agriculture Can Solve It
In 1958, geochemist Charles David Keeling began measuring carbon dioxide (CO2) levels at the Mauna Loa Observatory in Hawaii. He believed CO2 levels were rising and wanted to prove it. The observatory’s high elevation and remote location provided accurate readings. By 1959, CO2 levels were 316 parts per million (ppm). As of May 2024, they had risen to over 426 ppm, the highest in over 4 million years.
The National Oceanic and Atmospheric Administration (NOAA) reported that today’s CO2 levels are similar to those during the Pliocene Climatic Optimum, 4.1 to 4.5 million years ago, when sea levels were much higher. This rise in CO2 is mainly due to human activities like burning fossil fuels, deforestation, and industrial agriculture. Our human-centered approach has damaged Earth’s natural systems. To protect our environment, we must adopt an eco-centric view, valuing all living things and maintaining ecological balance.
CO2 is essential for life, as plants convert it into energy and release oxygen. However, excess CO2, along with other greenhouse gases like methane (CH4) and nitrous oxide (N2O), traps heat in the atmosphere, causing global warming. For millions of years, natural processes kept these gases in balance, supporting abundant life. But since 1950, human activities have caused CO2 levels to rise rapidly.
Scientists warn that if Earth’s temperature rises more than 1.5 degrees Celsius above preindustrial levels, the consequences will be severe. The current global efforts are not enough to prevent a climate crisis. In 2023, record-breaking warmth and devastating wildfires highlighted the urgent need for action.
Pollution, particularly air pollution, has serious health impacts. It worsens respiratory infections and causes millions of premature deaths each year. To combat this crisis, we must stop burning fossil fuels, protect forests, and reduce methane and nitrous oxide emissions. Transitioning to renewable energy and sustainable agricultural practices are crucial steps. By taking action now, we can help protect our planet and ensure a healthier future for all.
