A very hearty good morning to all, here I come with another major topic of concern that is “ocean pollution”.
Our country India has a coastline of about 7500km with about 25% of population living in coastal areas. Some of the major cities located along the coast are Chennai, Mumbai and Kolkata.
In our country, there are 11 major, 16 intermediate and 78 minor ports and for the water bodies there are 14 major, 44 minor and 162 small rivers with the annual runoff of 1645 3^km.
Around 500M tonnes of sediments are discharged into the sea in India each year.
Now the problem of concern is ‘our Indian ocean is the second polluted ocean in the world after north pacific with approximately 1Trillion pieces of plastic’.
Around 365M tonnes of sewage effluents are being released into ocean from Mumbai and 396M tonnes from Kolkata.
These problems are some of the major threat to marine ecosystem.
Here I come on the good part, with advancing technology, significant attention have been paid to ocean pollution, so here I introduce “Mr trash wheel” been brought to existence by “Waterfront partnership of Baltimore, US”.
Mr. Trash Wheel combines old and new technology to harness the power of water and sunlight to collect litter and debris flowing down the river.
The river’s current provides power to turn the water wheel, which lifts trash and debris from the water and deposits it into a dumpster barge. When there isn’t enough water current, a solar panel array provides additional power to keep the machine running. When the dumpster is full, it’s towed away by boat, and a new dumpster is put in place.
Here is a short video which provides you the functioning of this machine-
The introduction of this concept can help in collecting our debris from water bodies and can make our water bodies safe and clean.
Kudos to the technology!!!!
