Trophic rewilding depends on the assumption that replacing lost megafauna with alternative species can generate similar benefits. This new review by Bescond-Michel et al. challenges that belief. 🌏🌐🧪
Harms of introduced large herbivores outweigh benefits to native biodiversity - Nature Communications
Using impact assessment frameworks, this study shows that the introduction of large mammalian herbivores outside their native range has predominantly caused negative impacts on native biodiversity globally. The authors advise caution regarding their further intentional introduction for conservation purposes.

40% yield drop expected for Europe.
And we are still discussing if a single DNA base change has to be considered as a GMO. And that just because the organic sector is complaining?
Decadence? madness? or both?

🚨NEW from me: the U.S. and Europe could experience a 40% drop in food production this century as temperatures rise, a major new study has found. "It's almost like in this context, those with the most to lose, lose the most," said Prof Andrew Hultgren, a lead author of the study.
U.S. And Europe Face 40% Drop In Food Production, Scientists Warn
Major study finds world's most productive farming regions are especially vulnerable to rising temperatures, and face steep declines in agricultural output this century.
