A podcast explores the story of the Mexican axolotl and its role in regulating Mexico City's temperature. It discusses the pollution of the city's canals and efforts to save the critically endangered amphibian. The podcast also follows fishermen harvesting clams in Italy, explores clam farming for carbon capture, and discusses the practice of eco-grazing with sheep.
The conservation of the Axolotl species and their wetland habitat in Mexico City is crucial for regulating the city's temperature and preventing a temperature increase of 2.5 degrees Celsius by 2057.
Clam farmers in the Po Delta of Italy are actively contributing to climate protection by farming clams, which capture carbon dioxide from the atmosphere and help mitigate the impact of climate change on the ecosystem.

Axolotl: A Key Species for Mexico City's Temperature Regulation
The Axolotl, a unique amphibian species, is native to the canals of Sóchimilco in Mexico City. However, due to water pollution and habitat degradation, the Axolotl has become critically endangered in the wild. Scientists and local farmers are working to bring the Axolotl back into its natural habitat through an old agricultural practice called the Chinampas. These floating gardens not only provide a suitable environment for the Axolotl but also play a vital role in regulating the city's temperature. If the wetland and the Axolotl population are not conserved, it could lead to a temperature increase of 2.5 degrees Celsius in Mexico City by 2057.
Clam Farming: A Climate-Friendly Solution in the Po Delta
In the Po Delta of Italy, clam farmers are not just harvesting clams, but also contributing to climate protection. Clam shells are made of calcium carbonate, which captures carbon dioxide from the atmosphere. By farming clams, fishermen in Jorro are actively reducing CO2 emissions and creating a more sustainable fishing practice. The clams not only provide a source of income but also contribute to protecting the Po Delta ecosystem, which is facing the impact of climate change.
Sheep as Eco-Friendly Lawn Mowers in France
Sheep are being employed as eco-friendly lawn mowers in various locations in France, including Euro Disney and vineyards in Bordeaux. Farmers and companies are opting for sheep as a natural and sustainable alternative to traditional lawn mowing methods. Sheep grazing reduces CO2 emissions and noise pollution, and they can access areas that mechanical lawnmowers cannot. This eco-grazing practice fosters a connection between humans and animals while efficiently maintaining green spaces. However, there are differing opinions on the environmental benefits, with some advocating for letting nature regulate itself without any grazing intervention.
Come on a journey from central America to France, to follow the story of the quirky, feathery-gilled Mexican axolotl with a key role in regulating Mexico City's temperature, to meet climate-conscious clam and oyster fishers in Italy, and to visit the backyards, vineyards and fun parks in France replacing their lawn mowers with sheep. Originally broadcast July 2023.
