According to a new study, as many plastic pollution in the world comes from ten rivers.
Top ten rivers-
Eight of them are in Asia.
Plastic accounts for so much because of poor waste management.
About 5 trillion lbs floating in the ocean for major sources
Like the Yangtze River and the Ganga-
Scientists say it can be cut in half.
Scroll down to see a large number of plastic fragments that endanger aquatic life, which are flowing into the ocean and even the most primitive waters.
But how to get there from inland cities has not yet been fully understood.
Now a study shows the top ten rivers
Eight of them are in Asia.
Poor waste management accounts for 88 to 95 of the global total load.
The team calculated that reducing the plastic pollution of these waterways by half could reduce the total contribution rate of all rivers by 45.

Basic resources and rivers may be the main transport route for plastic debris of all sizes.
His team analyzed debris data from 79 sampling points in 57 rivers
Micro-plastic particles smaller than 5mm in size and macro-plastic particles higher in this size.
Microplastics in particular, they say, can harm the health of marine life, but it is not possible to clean up all of this.
Blocking the tide, however, may help reduce potential hazards.
To do this, the researchers first need to have a better understanding of how plastic enters the ocean, Dr. Schmidt said.
Rivers flowing from inland areas to the ocean are the main carriers of plastic debris, but concentration patterns are not known.
These findings help fill this knowledge gap.
Dr. Schmidt brings together data from dozens of research articles and calculates that the amount in the river is related to \"poor management of plastic waste in the basin.

A recent report noted that China, Indonesia, the Philippines, Thailand and Vietnam have discharged most of their plastic waste into the ocean.
In previous studies, it was estimated that the Yangtze River would dump about 0. 727 billion of plastic into the ocean every year.
The Ganges river in India has caused moreabout 1.

But Dr. Schmidt thinks the problem can be further narrowed.
He said: \"It is estimated that the river with the highest plastic load is characterized by a large population --

These rivers are also located in countries where plastic waste is poorly managed (MMPW)

Data show that large rivers are particularly effective in transporting plastic waste.
Large river lanes such as the Yangtze River have a higher proportion than small rivers produce a higher proportion of the matrix W in the basin.
\"These three factors have led most of the plastic load estimates to be concentrated on large rivers that live in large populations in their basins.
Countries such as China or India that have high matrix metal oxide production can greatly reduce the plastic pollution of rivers by implementing appropriate waste management.
In industrial countries, while there is a well-developed waste management infrastructure, one way plastic waste enters the environment is by littering.
Pollution costs over £ 6 billion ($7. 9 billion)
It is estimated that 1 million seabirds, 100,000 marine mammals and countless fish have died.

\"In addition to the long-recognized emergence of plastic debris in marine environments, plastic debris has recently been detected in freshwater environments, and plastic debris can be found even in primitive, remote locations.
