Recently, an article replicated by multiple media in Spain has assured its bearer: Stop eating meat is not going to save the planet. Well, a new report from the prestigious medical journal The Lancet, which counted on the participation of 37 scientists from various disciplines, has just concluded that a radical change in our diet is necessary for human and planet health, which reduces more than 50% consumption of red meat and sugar.
This 3-year work by the EAT-Lancet commission specifically assesses how to feed 10 billion people by 2050 with a diet of planetary health & # 39;, a concept that refers to the "health of human civilization and the state of the natural systems upon which it depends." The report is of great interest as it attempts to establish for the quantitative scientific objectives which allow large-scale action to transform the global food system.
Scientists believe the data is strong enough to say that if we want to feed all of humanity in a healthy way without degrading natural ecosystems, immediate action is needed. This implies, in the first place, a shift to healthy diets that double consumption of fruits, vegetables, and nuts, and reduce to more than half of the added sugars and red meat (mainly reducing their excessive intake in richer countries) . ).
The report does not advocate vegetarianism, but a & dquo; Flexible diet & # 39; based mainly on foods of plant origin, but occasionally may include modest amounts of fish, meat and dairy products. According to the The Lancet, these changes in eating habits could prevent about 11 million deaths each year in the world, representing between 19% and 24% of all adult deaths.
"The food we eat and how we produce it determines the health of people and the planet, and today we are doing so much harm," he says. Tim Lang, a professor at the University of London and one of the committee members who did the study. "We need to revise this in a serious way, to change the global food system on a scale never seen before, in a way tailored to the circumstances of each country."
In addition to these changes in diet, the report also considers a combination of other strategies, including a drastic reduction of food waste and important improvements in food production practices.
As far as biodiversity conservation is concerned, the work of The Lancet raises the adoption of a "Middle Earth" strategy, which means conserving at least 80 percent of the wealth of pre-industrial species and protecting the remaining 50 percent of the Earth as untouched ecosystems. This also means better management of the oceans around the world, to ensure that the fishing industry does not have a negative impact on ecosystems and that aquaculture expands in a sustainable way.
"World food production threatens the climate stability and resilience of ecosystems. It is the biggest driver of environmental degradation and transgression of planetary boundaries," he says. Johan Rockström, a researcher at the Stockholm Resilience Center. "A radical transformation of the global food system is urgently needed."
