Millions of things around us

There are so many things to observe on our planet that it is difficult to count them. The living world is full of possibilities. There are a multitude of living organisms to discover. Several million species are known to exist, and new species are still being discovered. Some species are so different, so special, so impressive, that it's hard to believe they actually exist. We don't know all species that exist because we simply haven't thought about all the possibilities. The living world is infinite and can adapt to practically anything, anywhere.

Biodiversity is a big word to describe all the different living organisms, along with all the places (habitats) where they live.
