It's possible to make a milk substitute from oats and from many other plants. Today we learn about one plant you may not have thought of, and find out what else it can do for the planet.

Plastic pollution is a perennial problem. The Plasticology Project aims to be part of the solution.

Sunshine? Let's not waste it. Let's install more solar panels and increase the nation's energy security. But wait, amid warnings of a possible food crisis should we be covering agricultural land with solar panels?

How do we manage the message? How do we influence public opinion? This seems to be a recurring theme for the Sustainable Futures Report , which is hardly surprising, because it's important.

I spoke to Guy Doza, a man whose business is communication. He's a prize-winning speaker and he's recently written a book on rhetoric.

...but I haven't made up my mind about the Prince of Wales yet. Is the Monarchy Sustainable?

This week: monarchy versus republicanism, ownership of land, agriculture and food production, a UN climate conference, warnings that we should use no excuse to justify expanding fossil fuel production, warnings of stranded assets, rapidly rising fuel costs, and is that electric car as clean as you thought?

The Wednesday Interview

I talk to Tinia Pina, CEO of Re-Nuble, about how her organisation uses commercial vegetable waste to produce a nutrient feed for hydroponic farmers. They use sea-food waste from fish processors too. It makes a biodegradable substrate to support the hydroponic plants.

The Wednesday Interview

I talk to Shameek Ghosh from Trustrace about building ethical supply chains for the fashion industry.

In Australia there is a new government. Will it reverse the climate scepticism which seems to have been a hallmark of the previous administration? Here in the UK a responsible investment manager at a major financial institution takes an interesting slant on his job and gets suspended as a result. Questions are asked whether a charity with a view on climate science is in fact a charity or could it be a lobbying group? UK ministers have decided that now is not quite the time to require corporate environmental disclosure, inviting the question if not now, when? There's more bad news from Hinkley C, (I keep having to remind my spellchecker that there's no 'C' in Hinkley - is that an omen?) but there's a ray of sunshine from Oberlin, Ohio in the United States.

Today I'm talking to Jake and Amee, creators of the S'wheat reusable plant-based water bottle. (Very special thanks to them for going through it all twice, because first time I forgot to turn the recorder on.) We're talking about protecting the environment, in particular protecting it from plastic waste.

Incidentally, there's a detailed analysis of the impact of plastic pollution, including the number of decades or centuries it takes for common plastic products to degrade, on the Happiness Without website.

Today is World Bee Day

This week, should the Guardian's Carbon Bombs be defused? There's a new report from the World Meteorological Organisation on the State of the Global Climate 2021, I learn about a country where supermarkets accept Bitcoin while IEMA warns about the energy cost of Bitcoin mining, and there's a prospect of new pandemics.
