what would happen if a lot of the animals are going to be extinct??

Wild forests and grasslands would die because they are adapted to rely on animal decomposers as well as pollinators and seed dispersers. This would cause abrupt loss of rainfall, atmospheric change and climate change.

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
