History of taking bath


Over the millennia, humanity bathed in natural waters, simply because there was no other. The lower population density living in the landscapes of yore and the absence of contamination allowed this, in some parts of the world until today. Thus, one took a bath without concern. The first “pools” were invented 3,000 years before [...]

With spring a new inhabitant arrived at our biological pool. For some time now we have been wondering about cut leaves of aquatic plants floating in the pool, a phenomenon that usually does not happen. And, approaching the pool, someone was making sudden jumps, fleeing from the bank into the depths of the water. [...]

The vegetation reacts directly to the presence of light and rising temperatures and dresses in more vivid colors. Suddenly, [...]

Opposite-leaved Pondweed


Aquatic plants, at least underwater ones that live submerged, always under water, are a subject for few specialists. Anyone who is not one of these specialists is seeing nothing more than something green under water. Underwater plants seem all to be the same, something chaotic, at best this underwater jungle is understood as oxygenation plants. [...]
