Every day, humans produce millions of tons of garbage. Although a lot of garbage is buried underground, there are still some accidental or illegal ways to enter the ocean.
Now, researchers have edited a new database, from the notorious "garbage patch" of the North Pacific to the world's beaches and garbage dumps in the ocean, revealing how widespread marine debris is.
The beautiful ocean has five large patches that are still expanding all the time, and these so-called big patches are the garbage islands that are known to float on the sea.
LITTERBASE and its corresponding maps collected data from more than 1,000 studies from 1960 to 2017. The most polluted locations have more than 10 billion garbage dumps per square kilometer, including some beaches in South Korea and Jordan, as well as offshore waters.
Most of the waste (nearly 70%) is plastic, others are metal and glass. Microplastics (plastic particles less than 5 microns in diameter) are especially popular. This is because large pieces of plastic waste are decomposed in daylight and ocean currents.
The human waste means that life on the seabed is not easy: the database also shows that more than 1,200 aquatic species, including mammals, fish, crustaceans, and other animals, are swallowed, lived, and entangled. contact.
