So sad to sea...

But Sir David says we can still save our oceans

- Chloe Govan

BEAUTIFUL bottle-nosed dolphins swim out of the blue and into view in a wildlife documentary that will deliver a devastatingly sad message as it hits cinema screens today.

The dolphins - and most of these stunning ocean species - are featured in Sir David Attenborough's latest film because they are under threat. It brings the plight of our seas into sharp focus as underwater worlds full of colour, movement and life are transformed into murky wastelands because of man-made pollution, global warming and over-fishing.

While Sir David presents the tragedies of our oceans, he also reveals there is still time to save them and the planet.
