Saving the planet the algal way

Nowadays we are all conscious of the depletion of our planet's resources and with it the decline of the natural world. So how about a raincoat made out of algae?

Charlotte McCurdy has used algae to create a bioplastic which is durable and carbon-negative. A raincoat made from this plastic has been handmade and is on show. You can see what it looks like and read about the idea behind the garment on Dezeen.  

Although a prototype at present with no schedule for production yet, this project shows how it is possible to use abundant natural resources to create plastics which are renewable and biodegradable. I wonder how long it will be until we have plastic entirely made from such sources?
