About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

This is the best summary I could come up with:


One of them is Russia’s Wrangel Island, a nature reserve under Unesco protection that is often called a polar bear maternity ward.

Preparations for the expedition to Wrangel took nearly two years, and last August we finally set off for the north of Chukotka on a small ice-class sailing yacht.

Finally, after passing Cape Dezhnev and heading for Wrangel Island, we began to encounter floating sea ice, which was unusual for the time of year.

Later I asked one of Russia’s top polar bear experts, Anatoly Kochnev, what causes the animals’ behaviour – why do they love to sit in the buildings?

The biologist, who worked in Chukotka and on the island of Kolyuchin for many years, told me that, first of all, polar bears are very curious by nature, so they always attempt to get through any unlocked window or door.

And looking at the main photo in my life at the moment, the one named House of Bears, I think that sooner or later all human-made things on Earth will cease to exist – buildings, cars and computers will all meet their end.
