THE STATE OF OUR SEAS
Marine litter is a menace that has severely disturbed the intricate links of the fragile aquatic ecosystem. Unregulated dumping of human-related waste and by-products (both biodegradable and otherwise) has caused disproportionate variations in the composition of the ecosystem, leading to extinction / exodus of species, and destruction of rich habitats like the coral reefs.
As per NOAA (
https://oceanservice.noaa.gov/facts/deadzone.html), hypoxic zones are areas in the ocean where the oxygen concentration is so low that animals can suffocate and die, and as a result are often called "dead zones." Runoffs from farms and cities drains into rivers, which utlimately meet the sea. This runoff contains an overabundance of nutrients from fertilisers, wastewater treatment plants, and other sources. The term “dead zone” is apt, since most marine life either dies, or, if they are mobile such as fish, leave the area. Habitats that would normally be teeming with life become, essentially, biological deserts.
Not only is this harmful for the environment, and ultimately for the humankind as a whole, this phenomenon is also affecting the livelihoods of millions of coastal fishing folks across the world, who solely depend on the catches from the shallow waters for sustenance.
