Global Freshwater Fish on the Verge of Extinction, Study Reveals

Fresh water fish population is under threat of extinction. Study has indicated that the global population of migratory freshwater fish has plunged by 76 percent since 1970. Populations of larger fish species had declined by “catastrophic” 94%.

The reduction of freshwater fish species is as a result overfishing, destructive fishing practices, invasive species, pollution, disruption of river ecologies and climate change. Irrigation and construction of dams was listed as a disruptive habitat that interfered with the existence of freshwater fish.

A report that was published by 16 global conservation organizations, dubbed The World’s Forgotten Fishes indicated that 16 freshwater fish species were declared extinct in 2020. World Wide Fund for Nature (WWF), which was part of the investigative team, revealed that only 15% of UK Rivers had decent ecological status.

WWF further revealed that the leading damage was caused by sewage outflows and farm pollution. In UK waters, the burbot and the sturgeon have disappeared and the salmon is also waning.

“Freshwater habits are some of the most vibrant on earth, but they are in catastrophic decline. The UK is no exception – wildlife struggles to survive, let alone thrive, in our polluted waters,” stated, the WWF chief adviser, Dave Tickner.

The report recommended for the government to enforce existing laws to restore freshwater habitat, strengthen the environment protection bill and set global targets for the reclamation of nature.

In 2017, the International Union for Conservation of Nature (IUCN) listed 455 critically endangered fish species, 643 endangered and 1245 vulnerable.

How Human Noise Kills Marine Species, as revealed by Scientists

Scientists have warned that the discord of noise made by humans is harming marine species . A comprehensive assessment revealed that large noise from human activities was as harmful as pollution, overfishing and climate change . The study that was conducted by the Journal Science exposed how marine animals can hear from far distances than they can see or smell. According to a report published in the Guardian, most of the marine life uses sound to catch prey as well as attracting a mating partner. Prof Carlos Duarte of King Abdullah University in Saudi Arabia argued that: “Marine animal can only sea up to around 10 meters, smell up to around a hundred meters, but they can hear across the entire ocean basins.” The research concluded that sound “is very important in the marine ecosystems, and noise is pervasive, affecting animals at all levels .” The increasing cacophony in the marine habitat is interfering with how marine animals respond to various survival...

Carbon dioxide to Make Jet Fuel, Study Reveals

Photo Source: twitter.com Aircrafts release a lot of carbon dioxide in the atmosphere which contributes to climate change. A research that was conducted by Science News and reported on December, 22 2020 stated that there was a new iron-based catalyst that has been invented to convert carbon dioxide into jet fuel. It is only a matter of time that carbon dioxide pumped to the atmosphere by planes could be sucked and used to power the same. The air travel’s footprint in carbon emissions could be tremendously curtailed, if the carbon dioxide that is released is recycled to generate fuel. As per Science News reports, Air transport contributes to about 12 percent of the entire transportation carbon-related emissions. Unlike cars, aircrafts cannot carry bigger batteries which can be run on electricity generated from wind or solar panels. The current breakthrough in the conversion of carbon dioxide to fuel involves cheap ingredients such as iron and transformed through a single s...

Why Mt Kenya Leaders are wary about Change of Guard

As 2022 succession battle gains momentum in Kenya, leaders drawn from Mt Kenya region have become more concerned of their political future and survival. Mt Kenya region is predominantly occupied by the agikuyu, ameru and aembu communities. The region has produced three out of the four presidents. It boosts about the tyranny of numbers, thus making the region a battle ground for leaders from other region seeking to succeed President Uhuru Kenyatta. Central alone produced Mzee Jomo Kenyatta, Mwai Kibaki and Uhuru Kenyatta as presidents. The only other Kenyan president drawn out of the region was Daniel Arap Moi. In the recent past, the region has gone against the tide of State operatives as a sign of revolt over what they term as negligence from the government, despite electing one of their own to the much coveted seat. Deputy President William Ruto has taken advantage of the brewing rebellion through making serious political forays in Central and its vicinity. ODM leader Rail...
