Why is Pollution a Global Issue: Urgent Challenges and Shared Responsibility

This extensive article delves into critical global environmental challenges, ranging from the Fukushima water release to water scarcity, climate change, biodiversity loss, and marine pollution. It aims to inform and engage readers by providing a comprehensive overview of these complex issues, emphasizing their interconnectedness and the need for collective global action. While its length may deter some, it serves as a valuable resource for those seeking in-depth insights, whether they are students, activists, policymakers, or individuals passionate about safeguarding the planet and fostering environmental responsibility.

Fukushima Water Release Sparks Global Concern

On August 24th, Japan took a significant step by releasing water from the Fukushima nuclear accident into the ocean. According to TEPCO, they have gradually released around 460 tons of this water into the sea each day for a total of 17 days, amounting to roughly 7,800 cubic meters of water contaminated with nuclear materials. In 2023, this discharge will happen four times, each time releasing about 7,800 tons, adding up to a total of 31,200 tons. It’s worth noting that there’s a staggering 1.34 million tons of nuclear-contaminated water stored at the Fukushima Daiichi Nuclear Power Plant.

Understandably, this incident initially caused widespread panic. This reaction makes sense because it taps into humanity’s deep-seated fear of nuclear issues, particularly concerning their long-term impact on the environment. People are most concerned about how this released water will affect not only the current generation but also future generations when it enters the environment.

Currently, our global environment is facing monumental challenges. Since the onset of the industrial age, human activity has caused unprecedented damage to our surroundings. The air we breathe, the water we drink, and the soil we depend on have all suffered severe pollution. A multitude of ecological crises loom menacingly, posing substantial threats to our planet. The quest for environmental protection is an ongoing journey, with much work still ahead of us.

Water is an essential resource, but it’s facing serious challenges in China and around the world

In China, each person has access to less fresh water than the global average. This year, the United Nations World Water Development Report revealed some alarming facts: a staggering 2 billion people worldwide lack access to safe drinking water, and 4.6 billion people don’t have proper sanitation facilities. Moreover, 2 to 3 billion people endure water scarcity for at least one month every year. These statistics highlight a looming global water crisis, with projections indicating that the number of urban dwellers facing water shortages could double by 2050.

The root causes of these water shortages can be traced to two primary factors: water quality and water quantity.

Concerning water quality, human activities have recklessly discharged pollutants into rivers, severely degrading the quality of many freshwater sources. Even regions that were once blessed with abundant freshwater are now grappling with water scarcity crises due to the spread of pollutants.

Currently, our planet grapples with a staggering issue: over 420 billion cubic meters of sewage find their way into rivers, lakes, and seas each year worldwide. This pollutes a whopping 5.5 trillion cubic meters of freshwater, equivalent to more than 14% of the total global freshwater supply.

The consequences of water pollution are dire, posing a grave threat to human health. In developing countries, over 1 billion people consume unsafe water, leading to the tragic deaths of more than 25 million individuals annually. Shockingly, approximately 5,000 children lose their lives daily due to drinking contaminated water. Another concerning statistic reveals that around 170 million people rely on water tainted by organic pollutants, while 300 million urban residents grapple with the burdens of water pollution.

Epidemiological studies conducted in regions with high liver cancer rates pinpoint drinking water contaminated by algal toxins as the primary cause of this devastating disease. Moreover, waterborne illnesses claim nearly 2 million preventable lives worldwide each year, with the most vulnerable being children under the age of 5.

Turning to the issue of water quantity, global warming has ushered in shifts in rainfall patterns. Periods of intense rainfall are frequently followed by prolonged droughts, culminating in severe water scarcity crises.

In China, the per capita water resources are significantly lower than the global average, and the distribution of these resources is strikingly uneven. Concurrently, since the initiation of economic reforms and opening up, rapid industrialization has resulted in vast quantities of untreated sewage being released into rivers, lakes, and even underground water sources. These practices have only exacerbated the water scarcity predicament within China.

Air pollution and the looming specter of global warming are pressing challenges confronting humanity today

Global climate warming stands as one of the most critical crises we face. Recent years have borne witness to extreme weather events that have left an indelible mark, like the torrential rains in Zhengzhou in 2021 and the floods in Hebei this year. These events are closely tied to global warming. As ocean temperatures rise and water evaporates and heats up more swiftly, a significant amount of water vapor is transported into the atmosphere, resulting in sudden and intense rainfall in certain regions. These heavy rains can lead to catastrophic consequences such as floods and mudslides.

Furthermore, global warming has accelerated the melting of Arctic and Antarctic ice caps, steadily pushing sea levels upward. This has had dire consequences for polar bears and penguins, who have lost their habitats and seen their populations dwindle significantly. Low-lying countries and regions are now vulnerable to submersion, and there is a worrisome possibility that viruses long frozen in the Arctic and Antarctic may reawaken, posing threats to humanity.

In addition to these challenges, as atmospheric temperatures rise, evaporation rates increase. Arid areas are grappling with more severe challenges and are on the brink of accelerating desertification.

March of this year marked a pivotal moment when the United Nations Intergovernmental Panel on Climate Change (IPCC) released its comprehensive report titled “Climate Change 2023,” the sixth climate change assessment report. This report emphasized that climate change is not merely “likely” to be driven by human activities but is now an “established fact” beyond dispute. It revealed alarming trends, including a global sea-level rise of 0.2 meters from 1901 to 2018, faster than any century in the past 3,000 years. In 2019, global carbon dioxide concentration reached 410 ppm, a level not seen in the past 2 million years. Moreover, extreme weather events have become five times more frequent in the past 50 years. UN Secretary-General António Guterres issued a stark warning at the Petersburg Climate Dialogue, asserting that it’s a choice between action and peril.

In the face of this pressing global warming crisis, humanity must take decisive action.

Soil pollution and the relentless advance of land desertification present a grave concern, particularly in the severely affected northwest region of China

Clean and safe soil is an indispensable resource for human survival on our planet. Nearly all our food, be it vegetables, fruits, grains, or animal products like meat and dairy, originates from the earth, nurtured by soil. Regrettably, soil often remains an unsung hero, overshadowed by the pressures of industrialization, warfare, mining, and intensified agriculture, which have led to widespread soil pollution worldwide. Concurrently, rapid urbanization has rendered soil a dumping ground for mounting urban waste.

The repercussions are twofold: soil pollution not only impairs plant metabolism, diminishing crop yields, but it also renders crops unsafe for consumption, thereby jeopardizing food security.

Moreover, soil contaminated with hazardous elements such as arsenic, lead, and cadmium, as well as organic compounds like polychlorinated biphenyls and polycyclic aromatic hydrocarbons, and even pharmaceuticals like antibiotics and endocrine disruptors, pose a significant threat to human health.

Alarming statistics from the United Nations News indicate that an area of land equivalent to a football field erodes every five seconds across the globe. If this trend persists, it is predicted that 90% of the world’s soil will confront a degradation crisis by 2050.

Soil degradation stems from both natural and human-driven factors. Unplanned land reclamation, overgrazing, and reckless deforestation, propelled by human activities, have accelerated grassland deterioration and forest depletion. This has led to soil erosion and wind erosion in regions once blanketed in lush vegetation, gradually morphing into deserts.

Among the nations hardest hit by desertification are China, Afghanistan, Mongolia, Pakistan, and India. Inner Mongolia, in particular, has witnessed a surge in desertification over the past decade, with a staggering 76% of its area now grappling with the looming threat. This escalation is also a chief contributor to the recent upsurge in sandstorms.

If the scourge of desertification persists unchecked, humanity will undoubtedly be confronted by a surge in natural disasters.

The dramatic plummet in biodiversity is a sobering consequence of human actions, with a staggering 1 million species teetering on the brink of extinction

Our impact on the environment has taken a severe toll on ecosystems, causing a sharp and disturbing decline in Earth’s biodiversity. Over the last four decades, our planet has witnessed a staggering 68% decline in biodiversity. The rate at which species are vanishing is accelerating, and the United Nations has sounded the alarm, estimating that a million species currently hang perilously close to extinction.

The ocean, vital to our planet’s delicate balance, bears the scars of pollution and climate change. The coral reef ecosystem, a vibrant hub of marine life, is suffering relentless destruction. These reefs, though covering less than 0.5% of the Earth’s surface, are home to 25% of the global population and support one-third of the world’s fish, offering refuge, sustenance, and breeding grounds. The ravaging of coral reefs has precipitated a precipitous drop in marine biodiversity.

Land-based ecosystems have fared no better, falling victim to human encroachment, the relentless expansion of industrial and agricultural land, and overexploitation of grasslands, rainforests, and wetlands. Latin America, home to the world’s largest tropical forest, has borne the brunt of biodiversity loss, experiencing a staggering 94% reduction in species richness over 40 years, marking it as one of the most severely impacted regions globally.

For instance, the Amazon rainforest, an ecological marvel, saw its destruction surge from 41.5 million hectares to a staggering 58.7 million hectares within a mere decade, from 1990 to 2000—equivalent to twice the size of Portugal. Rampant deforestation, coupled with the grim specter of climate change, has left this critical region vulnerable to recurrent destruction. When fires rage through these lands, they inflict severe harm on forest-dwelling species, posing a grave and imminent threat to the entire forest ecosystem’s biodiversity.

The destruction of marine ecosystems is an urgent concern, exacerbated by the pernicious discharge of pollutants into our oceans

Presently, the marine environment grapples with a multifaceted pollution crisis, tainted by plastics, oil, and even nuclear radiation.

Startling statistics reveal that a staggering 8 million tons of plastic inundate our oceans annually. To grasp the magnitude of this issue, imagine a truckload of plastic being dumped into the ocean every single minute. Driven by powerful ocean currents, this plastic deluge disperses to every corner of the sea. Currently, our oceans are marred by five major “garbage islands,” including the infamous Great Pacific Garbage Patch, the North Atlantic Garbage Patch, the Indian Ocean Garbage Patch, the South Pacific Garbage Patch, and more. These garbage islands represent vast agglomerations of oceanic refuse. Guided by ocean currents and wind patterns, they amass in specific regions, forming stable epicenters of trash. These islands aren’t mere surface flotsam; some are as thick as 30 meters and encompass colossal areas. In fact, the Great Pacific Garbage Patch exceeds the size of China’s Qinghai Province.

The menace of “ocean plastic” spells dire consequences for marine life. Countless creatures become ensnared in plastic debris, suffering deformities or perishing outright. Furthermore, plastics degrade into microplastics, which infiltrate marine animals and, eventually, the human food chain. Microplastics, impervious to human digestion, infiltrate cells and provoke cytotoxicity. Animal experiments confirm their role in causing cell death, inflammation, and metabolic disruptions. Microplastics now loom as a grave threat to human health.

History has borne witness to catastrophic oil spills, with the largest attributed to the Gulf War of 1991. During this conflict, tens of thousands of tons of crude oil flooded into the sea, creating three oil pollution zones spanning approximately 1,200 square kilometers. This catastrophe decimated the habitats of over 1,000 seabirds, with thousands perishing due to oil coating their bodies.

In our era of globalization, ecological risks are evolving in tandem with this global interconnectedness. These risks don’t discriminate based on a country’s size or wealth; they transcend borders, impacting every corner of our planet. Humanity worldwide has become part of a tightly-knit global community with a shared destiny. When ecological crises loom, no nation or territory can go it alone.

Water, air, and solid matter know no boundaries—they move freely across the globe. Environmental contamination in one part of the world has the potential to cascade, causing widespread ecological havoc. Think of polluted seas, vanishing tropical rainforests, and a ripple effect touching every facet of human existence. The environment inevitably deteriorates, underscoring the imperative need for global governance and sustained, collaborative efforts aimed at achieving lasting solutions.
