How will the increase in grass affect the animal populations?

An increase in grass can lead to a rise in herbivore populations, as more abundant food sources support larger numbers of grazers like deer, rabbits, and various insects. This, in turn, can attract predators, increasing their populations as well due to the higher availability of prey. However, if grasslands become overly dominant, it may limit the diversity of other plant species, potentially impacting the overall ecosystem and the variety of animals that rely on those plants for food and habitat. Ultimately, the balance of species and their interactions will determine the overall impact on animal populations.
