Dolphins are relevant to humans because we are still looking and researching our origins in the animal kingdom. There are similarities between dolphins and humans that do not exist with apes.

Also, dolphins act as ecological indicators which mean that they are bio-indicators on the condition of the marine environment and thanks to their behavior and health, we can detect and prevent some problems in the ocean biome, such as pollution or diseases that are expanding to populations of fish.

Likewise, they are predatory animals of various types of fish and marine animals, which contributes to the optimal function of the food chain where they inhabit. All these reasons directly affect humans, since a healthy ocean is synonymous with life on the planet.

To save dolphins, we need to reduce the dangers which dolphins face every day caused by human activities like:

1. Pollution of the oceans which cause the death of dolphins when they ingest garbage confusing it with prey.

2. Sound pollution that confuses cetaceans and some think it is the cause of numerous strandings.

3. Bycatch or accidental deaths in fishing nets when trying to catch another species like tuna.

4. Killing for commercial purposes in countries like Japan, Iceland, and Norway.

5. Global warming that reduces the availability or changes the behavior of prey and therefore dolphins.

Additionally, the most important activity that can be done to rescue dolphins is informing people about the threats that dolphins face so everybody can help to save them.
