Some populations in the Pacific Northwest are much healthier than others. When there are very few animals left within a range where they can safely mate with other animals and raise offspring, and there is no habitat containing a large number of those same animals, their species is in danger of extinction. After eating the poisoned fish, the eagles would lay eggs with very thin shells. Biodiversity hot spots have a high number of endemic species(species that occur nowhere else). An endangered species is a species that is likely to become extinct unless conservation measures and practices are (continuously) implemented, e.g. Invasive species can cause great economic and environmental harm to the new area.

A habitat includes not only the other plants and animals in an area, but all of the thingsneeded for the species' survival -- from sunlight and wind to food and shelter. Animals usually become endangered because of over hunting or the destruction of their habitat. Dinosaurs, for instance, lost their habitat about 65 million years ago. At body temperature, the latent heat of vaporization of water is 575cal/g575 \mathrm{cal} / \mathrm{g}575cal/g. The fur helps them to survive in a habitat where temperatures often drop below freezing. Probably Vulnerable but definitely NOT "near threatened" One way to try to protect species is to focus on areas with high species diversity.
