what is global pollution?
Global pollution refers to environmental issues where pollutants spread and accumulate on a global scale, posing universal threats to the Earth's ecosystem, human health, and sustainable development. Its essence lies in the fact that harmful substances released into the natural environment by human activities (such as industrial production, resource development, and transportation) exceed the self-purification capacity of the ecosystem, thereby breaking through regional boundaries and forming cross-border and cross-sphere pollution effects.
why global pollution is significant
It poses fundamental threats to the Earth's ecology, human survival, and global sustainable development, with its impacts spanning national borders, eras, and species.
Sharp Decline in Biodiversity: Pollution damages habitats, with over 1 million species worldwide now endangered due to contamination. The disruption of ecological chains can trigger a “butterfly effect”—for example, the reduction of bees due to pesticide pollution could lead to 70% of crops failing to be pollinated, threatening global food production.
Imbalance in Natural Cycles: Air pollution alters climates, causing frequent extreme weather events. Soil pollution weakens its purification capacity, exacerbating soil erosion and desertification. Globally, about 24 billion tons of topsoil are lost each year, equivalent to the disappearance of 30 football fields of farmland every minute.
More than 2 billion people worldwide lack safe drinking water, and approximately 500,000 people die each year from diseases like diarrhea and cholera due to consuming contaminated water. Additionally, data from the World Health Organization (WHO) shows that 99% of the global population breathes air with 超标 (excessive) PM2.5 levels, with around 7 million people dying prematurely each year from air pollution—equivalent to one death every 4 seconds. This has led to a significant increase in the incidence of lung cancer and cardiovascular diseases.
From a historical perspective, pollution issues have transcended the environmental realm. The decline of the Mayan civilization is believed to be linked to agricultural collapse caused by deforestation and soil degradation. Today, if pollution persists, it may breach the “tipping points” of the Earth’s ecological carrying capacity—for example, if ocean acidification exceeds pH 7.8, it will lead to the extinction of shellfish and the collapse of marine food chains—thus stripping human civilization of its natural foundation for survival.

5 CRITICAL POINTS EVERYONE SHOULD KNOW
- Global pollution refers to environmental issues where pollutants spread and accumulate on a global scale, posing universal threats to the Earth’s ecosystem, human health, and sustainable development.
- Global pollution poses fundamental threats to the Earth’s ecology, human survival, and global sustainable development, with its impacts spanning national borders, eras, and species.
- Everyone can contribute to solving global pollution.
- If the international community does not strengthen cooperation to control pollution, global pollution will continue to deteriorate due to accelerated climate change, rising health risks, etc., but it can be mitigated by the development of renewable energy and the application of green technologies, among others.
- Water pollution, land pollution, and air pollution are the core manifestations of global pollution, affecting the hydrosphere, pedosphere, and atmosphere respectively. The three are closely linked through material cycles—for example, acid rain transfers air pollution to soil and water, while agricultural runoff carries land pollution into rivers—collectively forming a composite ecological threat.
