The most common cause of death for wolves is conflict with people over livestock losses. While wolf predation on livestock is fairly uncommon, wolves that do prey on them are often killed to protect the livestock. Defenders is working with livestock owners to develop non-lethal methods to reduce the chances of a wolf attacking livestock. These methods include fencing livestock, lighting, alarm systems and removing dead or dying livestock that may attract carnivores like wolves.

Another serious threat is human encroachment into wolf territory, which leads to habitat loss for wolves and their prey species.

As the seas and oceans warm, dolphins are being seen more frequently in colder waters outside their historic ranges. Due to the rapidly rising oceans temperatures, the dolphin’s primary food sources are seeking deeper cooler waters. Scientists are concerned that the dolphins will have difficulty adapting as quickly as necessary to find new feeding grounds to sustain their populations.

Some dolphins that live in areas where rivers and oceans meet, known as brackish waters, are also losing habitat as ocean levels are rising due to global warming.
