Many subalpine lakes may look beautiful and even pristine, but new evidence suggests they may also be contaminated with potentially hazardous plastics. Researchers say those tiny microplastics are likely finding their way into the food web through a wide range of freshwater invertebrates too.
The findings, based on studies of Italy's Lake Garda and reported on October 7th in Current Biology, a Cell Press publication, suggest that the problem of plastic pollution isn't limited to the ocean.
Scientists have discovered a diverse multitude of microbes colonizing and thriving on flecks of plastic that have polluted the oceans—a vast new human-made flotilla of microbial communities that they have dubbed the "plastisphere."
Less than half of the 280 million metric tons of plastic produced each year ends up in the landfill. A fair bit of the rest ends up littering the landscape, blown by the wind or washed down streams and rivers into the sea.
So far Americans spend $520 million a year to clean up plastic litter washing up on beaches and shorelines. Efforts to clean up the oceans' enormous swirling gyres of garbage has an incalculable cost. Thus, much of the focus has been on how to stop the river of trash from entering the ocean.
A 70,000 mile expedition by a tiny research ship gives us a snapshot of life in the depths of the world's seas.
Up to one million new species of microscopic sea life have been observed for the first time, promising new revelations about the marine ecosystem that could revolutionise our understanding of climate change's impact on the world's oceans.
Each new life form was discovered by the crew of just one small research vessel, the Tara, which has recently completed a two-and-a-half year, 70,000 mile expedition.
Sharp increase of small plastic debris in the 'Garbage Patch' could have ecosystem-wide consequences.
A 100-fold upsurge in human-produced plastic garbage in the ocean is altering habitats in the marine environment, according to a new study led by a graduate student researcher at Scripps Institution of Oceanography at UC San Diego.
The United Nations estimates that each one of us uses nearly 140 kilograms of plastic each year. At least 6.4 million metric tons of that plastic has ended up in the oceans.
Environmental activist Captain Charles Moore has found that in some areas, plastic outweighs zooplankton - the ocean's food base - and is entering the food chain. Our reporter talked to Capt. Moore about his efforts to document ocean pollution.
Once upon a time, the oceans of our planet were beautifully clean. Not any more. Captain Charles Moore calls this 'the age of plastic.'
On every dive we will collect rubbish this month, as we always do. But this month being the Project Aware Dive Against Debris month, we hope to find even more volunteers showing their love for a clean ocean. We will also organise beach clean ups and rubbish collections in areas of our village where wind can easily "feed" the sea, in particular with plastic bags and bottles. Every Friday we will have a special offer on 3rd dives. Please check for updates. We look forward to seeing you :)
So today's little dive on the House Reef was a real success - I collected 2 bags full of trash / treasure... which amounted to - 17 plastic water bottles, 18 bottle caps, 2 plastic shampoo bottles, 4 food wraps / pots, 1 metal can and 2 flip flops - I'm just not going to comment on the flip flops any more!!! Great visibility on the dive and I also saw a lion fish, leopard flounder, lots of butterfly fish and a a spotted puffer! At the moment I feel like a real eco warrior - protecting the ocean planet one dive at a time!
Woo hoo!! Day 3 of my pledge to collect trashy marine treasure was a great success. Back out on the House Reef and today's haul was: 16 plastic drinks bottles, 1 plastic shampoo bottle, 16 plastic food pots (yoghurt pots), 1 flip flop (I still don't understand the amount of flip flops out there!), 1 piece of nylon rope and a badminton shuttlecock?????? Job done for the day. Back out with my collection bag tomorrow - one person can make a difference - in just 3 days that's a lot of plastic.......
