Plastic waste threatens lakes as well as oceans

Pollution with plastic waste is not confined to the oceans but poses a growing threat to lakes as well.

Researchers found levels of plastics in Lake Garda similar to those in marine environments

That is the view of researchers who found significant concentrations of the substance in Italy's Lake Garda.

They say the levels are similar to those found in samples taken from marine beach sediments.

They are concerned that these tiny plastic particles are accumulating in freshwater species and are "likely" to get into the food chain.

The research is published in the journal, Current Biology.

The problem of large amounts of plastic polluting the world's oceans hasbeen well documented in recent years.

As well as bigger pieces that can choke sea creatures when ingested, there is an equally serious issue with very small fragments called micro-plastics.

But research on the problems caused by plastic in lakes has been lacking.

Danger on the shore

This new study looked at Lake Garda, a large, sub-alpine body of water. The researchers found significant concentrations of plastic in sediment samples. On the north shore they found around 1,000 larger particles per square metre and 450 micro-plastic particles in the same area.

Helicopter ride to island home for rare red squirrels

A group of red squirrels have been transported by RAF helicopter to a new home on the Isle of Scilly.

Red squirrel are really rare in Britain so these lucky ones are being given a new home to try and boost their numbers.

The animals have been moved to get away from grey squirrels which carry a deadly virus which could wipe out the species.

They were flown to a small island off the English coast last month.
