" Eighth Continent " Discovered: It Made Entirely of Plastic
Did you know?
In the heart of the Pacific Ocean, far from land,
there floats a "new continent" four times the size of Japan.
This isn't a product of geological movement, but rather a vast garbage island composed of discarded plastic bottles, fishing nets, plastic bags, and countless other plastic fragments.
So, how did this human-free "island" come to be? And how does it resonate with our daily lives?
I. The North Pacific Garbage Vortex: A Man-Made "Eighth Continent"
For the past few hundred years, few people have ventured into the waters between California and Hawaii. Between the equator and 50 degrees north latitude lies the center of the Pacific's subtropical air currents. Because this area is a doldrums, the currents are slow, and floating debris accumulates there.
In 1997, American Captain Charles Moore, returning to Los Angeles after a sailing race, accidentally sailed into an area of floating plastic waste. He was surprised to see the true nature of this garbage sea: "It was like a pot of plastic soup. I couldn't get out of it for a whole week." This shocking discovery was later named the "North Pacific Garbage Patch," and environmental groups have dubbed it the world's "eighth continent."
Located between Hawaii and the coast of North America, this massive garbage patch covers an area of approximately 1.4 million to 3.43 million square kilometers—four times the size of Japan's 378,000 square kilometers and more than one-third the size of Europe. Its thickest point reaches 30 meters at its center.
Why has such a massive plastic waste dump appeared on the surface of the Pacific Ocean?
The reasons behind this are actually closely related to our daily lives. Since humans first synthesized plastic in 1907, plastic products, thanks to their low price and ease of processing, have rapidly permeated every aspect of our lives. However, it is precisely this overreliance on plastic products that has led to the massive generation of plastic waste.
So how did this garbage accumulate in the center of the ocean?
1. The North Equatorial and Japan Currents transport garbage eastward from the coasts of Asia.
2. The North Pacific Current propels garbage across the Pacific.
3. The California Current transports garbage southward along the American coast.
4. This ultimately forms a massive clockwise vortex system, like a cosmic black hole, continuously sucking in and trapping marine debris.
Even more worrying is its rate of growth—since its discovery in 1997, the area of this garbage patch has tripled; scientists predict that by 2030, its area could increase another ninefold!
II. Five Major Global Garbage Vortices: Plastic "Planets" in the Ocean
Sadly, the "Eighth Continent" in the Pacific is not an isolated case.
Five major garbage vortices exist in the global oceans: the Pacific, Indian, and Atlantic Oceans.
Over 80% of this garbage consists of discarded plastic products, including bottles, shopping bags, cutlery, mulch, soccer balls, basketballs, and tires.
Collectively, these vortices form a "plastic web" covering the world's oceans, with the North Pacific Ocean being the most heavily polluted, accounting for 42% of the global ocean plastic load. "The world produces 260 million tons of plastic each year, 10% of which ends up in the ocean—the equivalent of dumping a garbage truck full of plastic into the ocean every minute."
III. Tracing the Source of Waste: Who is Creating the "Eighth Continent"?
A study published in Science magazine has revealed the answer. By analyzing data from 192 coastal countries, the following were found:
Top 10 Countries Contributing to Marine Plastic Waste in 2023 (in tons/year):
1. Philippines: 356,371 tons
2. India: 126,513 tons
3. Malaysia: 73,098 tons
4. China: 70,707 tons
5. Indonesia: 56,333 tons
6. Myanmar: 40,000 tons
7. Brazil: 37,799 tons (the only non-Asian country)
8. Vietnam: 28,221 tons
9. Bangladesh: 24,640 tons
10. Thailand: 22,806 tons
Key Finding: Asian countries contribute over 75% of global marine plastic pollution. The Philippine archipelago, with its 36,289 kilometers of coastline and 4,820 rivers, contributes 35% of the global ocean plastic.
It's worth noting that plastic emissions are not only related to consumption but also closely linked to waste management capabilities. For example:
1. Although Malaysia's total plastic waste is only one-tenth of China's, due to its inadequate waste management system, the proportion entering the ocean is as high as 9%, far exceeding China's 0.6%.
2. Geography also plays a key role—island nations and regions with dense rivers and heavy rainfall are more likely to have land-based waste washed into the ocean.
IV. Ecological Disaster: When Plastic Enters the Food Chain
These floating plastics are more than just "visual pollution"; they are causing a profound ecological disaster. Through the food chain, such as salt and fishery by-products, marine debris and microplastics can enter the human body and harm human health.
1. Deadly Traps
Sea turtles mistake plastic bags for jellyfish, seals die after becoming entangled in abandoned fishing nets... According to Greenpeace, at least 267 marine species are directly harmed by plastic waste.
2. Invisible Poison
Even more terrifying is the "secondary harm" of plastic—plastic breaks down under ultraviolet light into millimeter-sized "microplastics," which, like a sponge, absorb millions of times more toxins (such as DDT and PCBs) than normal.
3. Return to the Table
These toxic plastics are ingested by plankton and passed up the food chain—small fish eat the plankton, large fish eat the small fish—ultimately ending up on human dinner tables.
Scientists have detected microplastics in human blood, placenta, and even breast milk.
The plastic we discard travels through the oceans and ultimately returns to our bodies.
The average lifespan of plastic is over 500 years. It never truly "disappears" but simply breaks down from large pieces into invisible particles, ultimately accumulating in organisms.
This means that a single plastic bottle we discard today could poison our descendants for a dozen or even more generations.
V. Saving the Ocean: From the "Eighth Continent" to a Plastic-Free Ocean
Faced with such a massive ocean waste, is humanity helpless?
Not at all! Current key solutions include:
1. Source Interception – River Trash Barriers
Since 90% of marine plastic enters the ocean through rivers, installing floating booms in major polluted rivers (such as the Pasig River in the Philippines and the Sitarum River in Indonesia) has become one of the most effective measures.
2. Ocean Cleanup – Artificial Floating Systems
The Ocean Cleanup project, founded by Dutch youth Boyan Slat, has developed a massive U-shaped floating barrier that uses natural ocean currents to gather and capture plastic waste. In 2023, the system recovered 18,000 tons of plastic in a single trip from the North Atlantic Gyre.
3. Policy Intervention – Global Plastics Convention
In 2022, the United Nations Environment Assembly adopted the "Resolution on Ending Plastic Pollution," aiming to develop a legally binding international convention by 2024. Countries like the European Union and Canada have begun implementing "Extended Producer Responsibility" systems, requiring plastic manufacturers to cover the costs of recycling and processing.
The "Eighth Continent" is expanding at a rate far exceeding our imagination. This 3.43 million square kilometer garbage island floating in the Pacific Ocean acts like a distorted mirror, reflecting humanity's consumption of nature without protecting it.
Every breath we take is connected to the ocean—and every breath the ocean takes is connected to you, because every breath comes from the ocean."
Saving the ocean is saving humanity, who depend on it for survival.
