Chapter 4 Glass Ponds
Do you aspire to have a small indoor pond?Small indoor ponds may not hold as many creatures as real ponds in the wild, but working around indoor ponds can be carried out without being disturbed by passers-by. If you have such a small indoor pond, you can observe every detail of aquatic animal life at any time.
Thanks to the highly skilled blacksmiths and carpenters, my indoor pond quickly went from drawing to reality. The iron-framed, glass-walled artificial pond rests securely on a well-sized wooden pedestal and is housed by me next to the sunny window of my home. I poured about ten to twelve gallons of water into the pool and threw in some small rocks covered in thick moss. It's these green, velvety mosses that keep the water in my pool as clean as ever. If you don't understand why, then join me to find out!

Small animals in the water, like us humans, need to inhale oxygen and expel carbon dioxide. But for plants, carbon dioxide is an indispensable nutrient**. Mosses and aquatic plants are able to absorb carbon dioxide from water and work wonderfully in their bodies to separate and release fresh oxygen for animals to breathe. On the reef entwined with aquatic weeds are many small blisters that twinkle like stars. They are constantly generating, rising, exploding, ......This is how aquatic plants constantly decompose carbon dioxide from water. At the same time, aquatic plants also release oxygen decomposed from carbon dioxide, which becomes the survival dependence of aquatic animals.
I often stare at the clusters of bubbles rising in the small glass pond, and my imagination wanders. Hundreds of millions of years ago, the first plants on this planet produced oxygen in this way, and all kinds of animals were born, evolved, reproduced, and continued to evolve into the world we see today. My glass pond may tell the story of the origin of all things
