The powerful gene editing technique CRISPR that allows us to rewrite DNA may soon provide a tool to help save our planet’s biodiversity. CRISPR has been described as ‘molecular scissors’ and is used to make targeted, precise changes to the DNA of plants and animals, with all the ethical questions it raises. Since it was developed by scientists 9 nine years ago, research into uses of CRISPR has been increasing in medicine and agriculture, as well as entering the fields of public health and enviro...

Realising your pet cat has brought home a 'gift' or perhaps a snack they plan to eat in front of you is never pleasant. Many owners will scramble to intercept and release the poor prey but that may be too little, too late. Cats have been blamed for an estimated 100million wildlife kills in the UK each Spring and Summer but it's hard to know what really goes on when they're out on the prowl at night. Birds, mammals, insects, amphibians...and sometimes the odd snake in some cases...but others don'...

Dr Seuss' fable of needless consumerism and environmental ruin, The Lorax, is half a century old this year. The 'shortish, brownish, oldish and mossy' character who 'speaks for the trees' increasingly features on placards at demos. Michael Rosen looks at the book's influence on the modern environmental movement and charts its journey from ignored to censored, embraced by the mainstream and inevitably turned into a Hollywood movie and used to sell SUVs. With Children's Laureate Cressida Cowell, W...

The COP26 conference in Glasgow in November is going to be a very important moment in tackling climate change. We are currently not on track to meet the goal of limiting global temperature rise to between 1.5 and 2 degrees above pre-industrial levels. According to the UN Intergovernmental Panel on Climate Change, we need to halve total emissions by the end of 2030 if we’re to be on track to hit the 1.5 degree target and avoid the worst effects of a changing climate. To close the gap between pled...

As some places in the world become too hot for humans to live, Tom Heap explores the cost to the environment of air conditioning. Air conditioning is one of the fastest growing sources of energy consumption, but it's already placing enormous strains on power grids, while also contributing to climate change. Across the world, building codes are making it virtually impossible to build new offices without it, and are setting "comfort standards" that don't take account of geography, climate or cultu...

It's fifty years since the first blossoming of environmental campaign groups. Friends of the Earth, Greenpeace and the organisation which was eventually to become the Green Party were all set up in the early 1970s - all within just a few years of each other. In part 1 of this two-part series, Tom Heap takes a look back over the last half century of environmental protest. He talks to some of the big names involved in green campaigning - from the early days up to the present and the rise of Extinc...

Last year wildfires in the Amazon made headlines news. This year we've hardly heard about them - but that doesn't mean they're not happening. In fact the number of rainforest fires in Brazil rose by almost 20% in June, reaching a 13 year high, according to government data. Some estimates now point to 2020 being an even worse year for forest destruction than 2019. Meanwhile, from California to Siberia, fires have been devastating landscapes and throwing more greenhouse gases up into the atmospher...

Record-breaking temperatures and months of severe drought fuelled a series of massive bushfires across Australia last winter. Dozens of people died and millions of hectares of bushland and forest were burnt. Australia's plant and animal life are well adapted to natural fire but the additional burden of climate change ensured that many of the fires were more intense and widespread than ever before. Much of the country's unique fauna had nowhere to hide. Peter Hadfield travels through the fire-rav...

Do you know how much water you use? Despite campaigns to reduce our personal water usage from around 143 litres each per day to closer to 100, it's not improving. Meanwhile Tom Heap has discovered that an innovation to a product we use every day, an innovation which promised to save water is actually making things worse. Billions of litres are being wasted every week – enough to supply the cities of Edinburgh, Cardiff, Sheffield, Manchester, Liverpool, Bristol and Belfast combined – welcome to t...

With an ever greater demand for more housing, and Boris Johnson calling for the country to "build buld bulid" post lockdown, Peter Gibbs looks at current trends in house-building. Are the government's plans for "garden communities" as environmentally-friendly as they sound? And how could developers be encouraged to build in a way which incorporates nature rather than squeezing it out? Produced for BBC Audio in Bristol by Emma Campbell.

Lockdown saw many more people jumping on bikes and walking - as much as a way to get out of the house as get around - but pollution levels dropped and nature could be heard without the background roar of traffic. Jheni Osman asks if this the way it could or should be? Has this given us a new way of thinking about how we get around and can city leaders bank on this to change the infrastructure to be 'car free'? After 100 years of city design being built around the private car, this is a rare oppo...

Just a few months ago politicians across the spectrum were promising trees, glorious trees, in abundance. In an unlikely game of Top Trumps the numbers of trees promised reached into billions, ultimately settling at an ambitious promise of 30,000 hectares a year by 2025. So, how are we going to reach this target over the next 5 years and is it even the right goal? Things have not begun well with thousands of saplings left to rot after they could not be planted due to coronavirus restrictions and...

Sound is what the world does. From the tiniest bugs to the largest whales, animals use sound to communicate, for example, they sing to attract a mate and establish a territory. But this is all happening against a background of man-made noise that was, until the last few weeks, increasing in volume all the time. So what happens if you can’t hear or make yourself heard or you are too stressed or distracted to behave normally? Andy Radford, Professor of Behavioural Ecology at the University of Bris...

Plastic waste is the scourge of developing countries. Many have poor waste collection and virtually no recycling. But there may be ways in which local people can put the waste to good use In Cameroon a child called Pierre Kamsouloum wanted to play football, but had no ball. He got the idea of melting soft plastic, the kind that food is wrapped in, and moulding it into a crude football. A few years later, without a job and looking for a way to make money, he came back to the idea, and realised th...

Every year billions of products are sold around the world in plastic packaging. But some countries lack a waste system to collect and recycle or dispose of the rubbish. The result can be that waste is dumped, set on fire or used as an accelerant in domestic fires. A new report by Tearfund claims to reveal the scale of the uncontrolled burning in six key countries. Tom Heap finds out what the implications of this are and asks if the product manufacturers which profit have a 'moral responsiblity' ...
