Plastic pollution is a gigantic problem. Our beaches and waters are littered with plastic, marine life ingests it or gets ensnared and particles are entering our food web and organisms. Microplastics are everywhere now.
More and more alternatives to plastics are being proposed these days, as the world wakes up to the immense “longevity” of single-use plastics.
One of these alternatives—seaweed—is the focus of Notpla, a London-based startup that has developed packaging that is designed to be composted, dissolved or consumed after use.
The decision to use seaweed was made after considering that it was abundant, grew fast, sequestered carbon from the air and did not require pesticides.
The popular dive spot is southeast of the Philippine capital, Manila.
BBC Philippine correspondent Howard Johnson joined dive professionals from Anilao Scuba Dive Centre as they resumed diving, following the national lockdown. The dive centre is affiliated to the United Nations Environment Programme’s Green Fins, which promotes sustainable marine tourism in South-East Asia.
A new study conducted at the Norwegian Institute for Air Research suggests wind-borne microplastics are a bigger source of ocean pollution than rivers, the route that has attracted most attention to date.
Airborne transport has received much less attention than rivers because only the smallest particles can be blown by the wind and their size makes them difficult to identify as plastic. The scientists concentrated on fine tyre and brake dust as there is better data on how these are produced than tiny microplastics from other sources, such as plastic bottles and packaging.
To understand sea turtle behavior around ocean plastics, the research team compared how sea turtles in a lab setting reacted to smelling odors of turtle food, ocean-soaked plastic, clean plastic and water.
The turtles ignored the scents of clean plastic and water, but responded to the odors of food and ocean-soaked plastics by showing foraging behavior. This included poking their noses out of the water repeatedly as they tried to smell the food source, and increasing their activity as they searched.
On 10 May 2018 David Jones will be talking on "Marine Plastic Pollution: How did we get here and what can we do about it?"
Plastic pollution is undoubtedly one of the biggest environmental issues we face at the moment. Plastic has only been in our lives for around seventy years, so how did we get to where we are, what went wrong? More importantly, what can we do about it?" David Jones.
Today George Eustice - the Environment Minister - responded stating that the Government would support an initial ban on cosmetics containing polluting plastic microbeads.
There is however a worry that the UK Government's ban may not be as robust as it should be.
Mr Eustice indicated to Parliament’s Environmental Audit Committee that the ban could be widened in the future to include microbead use in other products, such washing powders.
