Plastics on the farm; the truth about chlorinated chicken; winter in the Cairngorms
Plastics were at the heart of the government's 25-Year Environment Plan, which the Prime Minister revealed yesterday.
We now have ban on micro-beads in cosmetic products, the 5p charge for plastic bags is extended to all retailers - and next month there'll be discussions on a potential tax for single-use plastics.
So what does this anti-plastic message mean for farmers? Sybil speaks to Cotswolds farmer Tanya Robbins.
But plastics weren't the only focus of Theresa May's speech: other key themes included marine protection, increasing British woodland and protecting and enhancing natural capital.
Critics have said it contained too much talk, and too little action - with no concrete legislation to put the plan into law after Britain leaves the EU and therefore hold offenders to account. Others say the focus on a 'Green Brexit' is a ploy to win over younger voters ahead of the next election.

Yesterday we discussed post-Brexit trade negotiations with the US - and heard from the American Under Secretary for Trade, Ted McKinney - who said he was "sick and tired" of answering questions about chlorine-washed chicken, which he said hadn't been used "for a long time".
So what exactly do American processors use to disinfect their poultry? A representative from the US Embassy in London told us that FOUR chemicals are approved for use in disinfectant solutions for poultry - one of them being chlorine dioxide. They said it's the least common of the four permitted chemicals, and although they couldn't give us a percentage of how many American poultry producers are using it, they said it was very low.
To get some clarification, Sybil speaks to Matt Kilcoyne from think-tank The Adam Smith Institute - which last year published a report into why we should accept US chicken in the UK as part of a future trade deal.
As part of this week's Winter Livestock focus, we're visiting one of the toughest farming corners of the UK: the Cairngorms in Scotland. Bob Moncrieff is a tenant farmer near Nethy Bridge. His 20 cows and 280 breeding sheep graze mostly on the open hillside where there's been snow on the ground since the start of December.
