#TuDietaPuedeSalvarElPlaneta RepensandoElMañana

Are we destroying the planet with our food? At this new Rethinking Tomorrow event, Aitor Sánchez, a dietitian, nutritionist and food technologist, reflects on the relationship between food and climate change. On the occasion of the publication of his book ‘Tu dieta puede salvar el planeta’ [‘Your Diet Can Save the Planet’] (Paidós), we talk about what changes we can make to protect the environment.


Are we destroying the planet with our food? According to the scientific data, the answer is yes. We continue our thought forum Rethinking Tomorrow with an event dedicated to reflecting on how food and climate change are related and what changes we can make to safeguard the environment for the future.

Coinciding with the publication of his latest book ‘Tu dieta puede salvar el planeta’ [‘Your Diet Can Save the Planet’] (Paidós), we welcome to the auditorium the author Aitor Sánchez, dietitian, nutritionist, food technologist and writer of the bestseller ‘Mi dieta cojea’ [‘My Diet is Making me Sick’]. He speaks to Lucía Martínez, a nutritionist and science populariser, to find out how, in today’s world, something as routine as buying food can condemn or save the planet; it is up to us to become aware and make more responsible decisions to safeguard it.

To do this, we need to analyse how we got to this point, where the environmental stakes are high, and delve into each of the factors that have led us here. The carbon footprint generated by the number of miles our food travels, the cost of producing it, the way we farm animals, the social effects of unhealthy foods and the repercussions of plastic packaging are some of the topics we will cover. We will also suggest alternatives to promote the change towards responsible consumption.

The event, pre-recorded on the website (spanish):

#RepensandoElMañana is an ambitious initiative that aims to provide an overview of what the world will be like poscovid-19 and what challenges and opportunities we will face, with particular emphasis on topics like digital culture, education, climate change and sustainability.

The event was interpreted into Spanish Sign Language and was streamed on our website and on social media with the hashtags #RepensandoElMañana y #TuDietaPuedeSalvarElPlaneta.

You can now watch the event in our media library and listen to the podcast on the main podcast platforms.
