How many animals are there on the planet?

Zoologists cannot even tentatively name the number of animals on our planet. All due to the fact that we do not even know the number of animal species. Opinions vary from 1.5 to 60 million animal species. As you can see, in this situation, we cannot even imagine how many animals there can be on our planet. It is also worth considering the fact that every hour three species disappear from the face of our planet. This is due to natural selection and changes in environmental conditions. In addition, there are many species that have not yet been discovered by scientists.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
