How to prevent the extinction of the white-faced dolphin?

The white-faced dolphin is now in a stable position. It is no longer on the verge of extinction, although there are relatively few of them. Man did not catch these animals on an industrial scale, so they live peacefully in the waters of the Atlantic. But if their population declines again, then we will not be able to do anything to save the species, since we are not the cause of extinction. Every hour, 3 species of plants and animals die out due to natural selection and this is normal. Our task is not to destroy or change the habitats of animals.
