World ocean day 2022: Nigerian fishermen decry disappearance of aquatic species ,
As UN expressed worries over one million species faces extinctions .
As the world celebrate world international ocean day 8 June every year.
A Team of scientists and volunteer environmentalists has visited some River,sea, oceans with the aims raising more awareness to the general public on harmful effects of throwing plastic and other garbage, so as to save aquatic mammals.
Dr Piman Hoffman, science -climatologists and the Assistant Director, African Climate Reporters, attributed this development to indiscriminate dumping of chemicals, wastes and other adverse human activities to the extinction of marine animals.
According to him, humans have introduced significant number of chemicals into the environment which are very harmful to marine animals.
People need to stop indiscriminate dumping of wastes in the streets, gutters and their neighbourhood. As a people, we don’t have good waste disposal culture. This is very unpleasant and unhealthy.
He said that while some chemicals were designed to get rid of weeds and pests, a significant amount of chemicals were wastes from industrial and agricultural processes
While stressing that Since the 16th century, humans have driven at least 680 vertebrate species to extinction,
Hoffman expressed sadness over the attitude of companies who dumped chemicals into water sources without recourse to the consequences.
He said that an anytime chemical waste was released, it effect went into the environment and polluted the water.
“As it rains, the chemicals are washed into rivers, which in turn feed the waterfalls and then go into the ocean.
United Nation report Two years back indicates that One million plant and animal species are on the verge of extinction, with alarming implications for human survival,
More plants and animals are threatened with extinction now than any other period in human history, it concludes. Nature’s current rate of decline is unparalleled, and the accelerating rate of extinctions “means grave impacts on people around the world are now likely,”
Hoffman said that climate change and human activities had caused the extinction of many aquatic life and many were still going due to continuous dumping of hazardous wastes harmful to living organisms in water.
“We dump everything in the oceans, including plastic bags and other plastic debris, garbage, and toxic chemicals, crude oil, sewage and nuclear wastes.
“We kill thousands of aquatic animals daily without knowing the consequences, hence, there is need to halt this ugly attitude.”
The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. Due to human activities, populations of many species have become small and isolated.
The fishermen in an interview in Kaduna ,Kano, katsina narrated that they were generating huge revenue from species such as sardine, tilapia and others, many of which had disappeared from the rivers,streams
“we don’t see crocodiles ,hippopotamus, craps like before “
“many were gone, gone forever “
“millions of Aquatic animals are going extinctions silently in the sea and river “
“plastic pollution has outnumbers marine life “
They said that the population of the available species were also reducing from what it used to be some years ago.
fishermen in the Northern part of the country are crying out that there is a gradual extinction of fish species in the region, because the situation has degenerated over time. A fisher at Kangimi Dam kaduna Mohammed sani, said that many species of fish had gone extinct, while some others were almost disappearing gradually.
He said that for the past 20 years, fishes such as sardines and tilapia had completely disappeared, adding,
”we are forced to migrate from one river to another in search of other fishes for sale,
Mohammad further disclosed that even frogs and crabs have all disappeared. He called on people to stop dumping wastes into drainage channels and rivers to save aquatic animals from going into extinctions.
Another fisherman, mallan Danlami salami said : “Today, it is difficult to see crocodiles along the banks of River Kaduna. Similarly, frogs, tadpole, toads, crickets have virtually disappeared or have become extinct.”
He said that because fishermen were unable to make money from fishing, many of them gone into other vocations such as guarding houses and farming.
Two-third of world marine life is considered endangered species due to climate change and improper disposal of chemicals which affects living organisms in streams, Rivers or the oceans.
Marine life is the plants, animals and other organisms that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries. At a fundamental level, marine life helps determine the very nature of our planet. Marine organisms produce much of the oxygen we breathe.
