Applying circular economy principles to global plastic packaging flows could transform the plastics economy and drastically reduce negative externalities such as leakage into oceans, according to the latest report by the World Economic Forum and Ellen MacArthur Foundation, with analytical support from McKinsey & Company.
Widespread adoption of products labelled “biodegradable” will not significantly decrease the volume of plastic entering the ocean or the physical and chemical risks that plastics pose to marine environment, accord to a United Nations report released today.
The hunting ability and growth of sharks will be dramatically impacted by increased CO2 levels and warmer oceans expected by the end of the century, a University of Adelaide study has found.
Published today in the journal Scientific Reports, marine ecologists from the University of Adelaide’s Environment Institute report long-term experiments that show warmer waters and ocean acidification will have major detrimental effects on sharks’ ability to meet their energy demands, with the effects likely to cascade through entire ecosystems.
An international study led by a University of Queensland researcher has revealed more than half the world's sea turtles have ingested plastic or other human rubbish.
The study, led by Dr Qamar Schuyler from UQ's School of Biological Sciences, found the east coasts of Australia and North America, Southeast Asia, southern Africa, and Hawaii were particularly dangerous for turtles due to a combination of debris loads and high species diversity.
"The results indicate that approximately 52 per cent of turtles world-wide have eaten debris," Dr Schuyler said.
A report released today by the UN Environment Programme (UNEP) on the occasion of World Oceans Day recommends a precautionary approach toward microplastic management, with an eventual phase-out and ban of their use in personal care products and cosmetics (PCCP).
The study, entitled Plastic in Cosmetics: Are We Polluting the Environment Through our Personal Care: Plastic ingredients that contribute to marine microplastic litter' is a compilation of currently available knowledge on the linkages between cosmetics and plastic pollution in the oceans.
Micro-plastics – tiny pieces of plastic or fibres which may act as a pathway for persistent, bio accumulating and toxic substances entering the food chain – are increasingly being found in the oceans and may prove to be as harmful to marine life as more obvious, larger debris, such as plastic bags, according to a new report.
A landmark study, published in the journal Science on Thursday 13 February, reveals just how much plastic makes its way in the world's oceans and the top countries responsible for the ocean-bound trash.
About 8 million tons of plastic waste wound up in the world's oceans in 2010, and researchers warn that the cumulative amount could increase more than tenfold in the next decade unless the international community improves its waste management practices.
