Why do terrible things take away animals group at a time?

Terrible events, such as habitat destruction, climate change, and poaching, can drastically impact animal populations by disrupting their social structures, breeding patterns, and access to resources. When these pressures increase, entire groups can be affected simultaneously, leading to population declines or even extinction. Additionally, many species rely on social groups for survival, making them particularly vulnerable to sudden losses. Consequently, the interconnectedness of ecosystems means that the effects of such tragedies can ripple through animal communities.
