A rule of thumb for assigning topics to this category: if the article talks about the likely impact on humans, it's an environment topic, only the most global of which belong here. If it's an impact by humans, it does belong here. If it's about only one or a small or local group of species, it's a biology topic, only the most basic of which belong here.
