Placental mammals live in almost every environment on Earth. They are one of the most successful groups in the animal kingdom. Mammals in general are very successful and the majority of mammals are placentals. This group is so successful because they are endothermic. The only mammals that are not placentals are the marsupials (kangaroo, opossum, etc) and the prototherians (egg laying mammals). Environments that do contain mammals would likely be constrained to those that are very severe: The deep ocean, extremely high mountain peaks, etc. Otherwise you can find these animals almost anywhere.
