to sell it to industrial companies able to transform it into energy. The circle is complete.
These ecological transitions are now being called for by a growing number of players in the sector. At the UN Climate Action Summit in September, 19 leading agri-food industry signed the One Planet Business for Biodiversity commitment, promising to fight deforestation and promote soil regeneration through agriculture.
While these efforts are essential, they are unlikely to be enough. Preserving resources and ecosystems will also require a profound shift in our consumption patterns and dietary habits. This evolution is already under way.
Eating better: good for us... and for the planet
Our relationship with food has evolved considerably over the last ten years. As well as the debate on GMOs, consumers are concerned with the sources, quality and production methods of their food. Dozens of mobile apps and connected tools help us understand our bodies and our needs better, supporting appropriate diets, measuring changes in our metabolism and analysing the contents of our plates.
This evolution chimes with growing climate, environmental and ethical preoccupations. With intensive livestock rearing1 responsible for nearly 15% of carbon emissions, going vegan or locavore (eating foods produced locally) is more than just a fad. It expresses a rejection of systems that are no longer appropriate for the current state of our planet.
But should we stop eating meat? There is no global answer, because the nutritional needs of each population must be taken into account alongside dietary habits at global scale. Practices that are evolving according to trends, but which are above all subject to several criteria (level of development, purchasing power, religious practices, etc.).
For researchers from Johns Hopkins University2, two types of diets could successfully reconcile overcoming malnutrition with the fight against climate change.
While the first, a two-thirds vegan diet, combines vegan and omnivorous eating patterns, the second includes eating insects to reduce our environmental footprint. More and more professionals in the sector are embracing this path.
