Reducing plastic pollution by 5pc yearly may stabilise ocean microplastics: Study

New Delhi, (IANS) Cutting down plastic pollution by 5 per cent per year may help stabilise the level of microplastics -- plastics less than 5 mm in length -- on the surface of oceans, finds a study on Friday.

From human blood to testicles, to flora and fauna, microplastics have long been known as a significant environmental and health concern worldwide.

To predict its impact on oceans, researchers at Imperial College London and GNS Science developed a model of eight different scenarios of plastic pollution reduction starting from 2026 up to 2100.

The results, published in Environmental Research Letters, showed that a reduction in plastic pollution by more than 5 per cent each year will stabilise and also prevent the increase of microplastics in the ocean.

However, the modelling also predicted that even a yearly reduction of 20 per cent will "not significantly reduce existing microplastic levels, meaning they will persist in our oceans beyond 2100”.

Zhenna Azimrayat Andrews, from the Centre for Environmental Policy, Imperial College London noted that “stabilising microplastic levels is the first step towards elimination’’ as they “never be a completely successful removal” from oceans.

“But the current global output of plastic pollution is so great, that even a 1 per cent annual reduction in pollution would make a big difference overall,” added Zhenna.

Meanwhile, the UN Environmental Assembly (UNEA) aims to adopt a legally binding resolution to completely eradicate the production of plastic pollution from 2040, including ocean microplastics.

For this “a more coordinated international policy is necessary”, and “changes should happen on an industrial and commercial level”, the researchers argued, Reducing plastic pollution by 5pc yearly may stabilise ocean microplastics: Study | MorungExpress | morungexpress.com

Chester Zoo Celebrates as 11 Adorable Endangered Penguin Chicks Hatch–the Most for a Decade

Baby penguins hatched – Chester Zoo

It’s hatching season for Humboldt penguins at the Chester Zoo, and this year the keepers have seen a record number of chicks hatched.

The 11 chicks joining the colony are a delight for visitors and handlers alike, as well as a boon for the species which was recently classified as “Vulnerable” by the International Union for the Conservation of Nature.

Chester Live reports that the zoo has seen all 11 successfully make it through the first 40 days of life—the most delicate period for the flightless birds—and that now the naming process will begin.

The zoo has previously used themes to keep track of hatching groups and their years, with previous generations being named after NHS doctors, Olympic athletes, and retail chocolate bars, this year’s theme is flowers. Nettle, Thistle, Dandelion, Tulip, and Daffodil are among the confirmed names so far.

“We’re delighted to say that all of the chicks are looking really healthy and the parents have done a superb job of caring for their new arrivals up to this point. As keepers, our main role in raising the new youngsters is to ensure the adult penguins have all they need,” said Zoe Sweetman, team manager of parrots and penguins at the zoo.

“Sometimes this can mean providing extra fish, which the parents swallow, churn into a high-protein soup, and then regurgitate to feed the chicks. We also weigh the chicks regularly so that we can monitor their development—on average they’ve gone from a mere 80g to 2.5kg in just 40 days. It’s been a huge team effort.”

Chester Zoo is one of the UK’s most active institutions in the captive breeding of endangered species, and GNN has reported on their efforts raising the Philippine spotted deer, Andean bear, okapi, Sumatran tiger, Coquerel’s sifaka, cotton-top tamarin, Sulawesi crested macaque, and greater one-horned rhino.

In their natural habitat, Humboldt penguins are found on the coasts of Chile and Argentina, where their name comes from the chilly Humboldt current that brings frigid, nutrient-rich waters up from Antarctica.
