Reacción a "Extensive livestock has declined in regions such as Europe, and this has ecological consequences, according to a study"

The study is of good quality and addresses an important issue, the impact of animal densities on extensive livestock, daring to challenge the current academic consensus on the matter. I do not believe it has any methodological limitations.

Indeed, academic studies have so far focused on analysing the negative impacts of overgrazing on pastures. Without denying this evidence, it draws our attention to some currently overlooked facts: livestock density is declining in developed countries where there was overgrazing, but livestock density is increasing in the rest of the world. 

The decrease in livestock density, where it occurs, has the positive effects that would be expected according to the prevailing scientific literature, but negative effects are emerging that have not been given sufficient attention, such as forest fires and changes in CO₂ absorption capacity. On the other hand, where livestock density is increasing, the negative effects analysed in the literature are appearing. Therefore, in contrast to simplistic and unambiguous analyses, this article explains that, in this respect too, the world is much more complex than the scientific consensus was expressing.

The article seems to conclude that different developments are taking place in opposite directions in different parts of the planet, with positive and negative effects that must be taken into account and whose outcome is not as clear as the academic consensus had previously seemed to conclude.
