For my Taxonomy I decided to take a picture of my drawing of the ocean, and its habitants. The oceans are a huge, but very fragile system. This has become especially evident in recent decades, when pollution of ocean waters has reached unprecedented proportions. Meanwhile, not only the well-being of ecosystems depends on the state of water - human civilization itself largely depends on the oceans: it affects the weather and climate of the entire planet. That is why pollution of the oceans has become one of the most serious environmental problems of our time.
