Pollution and climate change are interconnected environmental crises that jointly threaten ecosystems, human health, and global sustainability. Air pollutants such as black carbon, methane, and ground-level ozone not only degrade air quality but also act as potent climate forcers, accelerating global warming. Industrial emissions, deforestation, and agricultural practices release vast quantities of greenhouse gases (GHGs), exacerbating the greenhouse effect and leading to rising temperatures, extreme weather events, and sea-level rise. Simultaneously, pollution from plastics, chemicals, and heavy metals disrupts terrestrial and marine ecosystems, weakening their resilience to climate stress. These overlapping impacts create feedback loops—for example, warming oceans intensify algal blooms and reduce oxygen levels, further harming marine biodiversity. Addressing this dual challenge requires integrated policies that reduce emissions, promote clean technologies, and enforce environmental regulations. Coordinated global efforts are essential to mitigate pollution, stabilize the climate, and ensure a livable planet for future generations.
