Cactus, ants, these natural things can be seen everywhere, so it is not unusual, but don't underestimate them.
Have you ever seen a group of tiny ants crawling on the wall, always carrying food as small as sand and walking around in groups? That tiny figure is very fragile. As long as it is crushed, its life may end like this. Although ants are small, they are very United. When an ant finds food, it is too big to carry it by itself, so it immediately returns to its nest and informs its partners that everyone can unite. If we can cooperate, we can stand firm in life.
Cactus live in desert areas, where the heat is unbearable and there are many ferocious beasts, and the situation is very dangerous. However, the cactus has lived there for a long time, but it has not become extinct. This is because it grows sharp thorns to adapt to dangerous environment, which makes animals helpless. This seems to tell us that we must overcome difficulties and rely on our strong perseverance to solve the external difficult environment. As the saying goes, "Nothing is difficult in the world, only if you put your mind to it."
There are so many revelations in nature that we can have a deeper understanding of life as long as we understand them with our hearts.
Fish have the ability to come and go freely in the water, so people imitate the shape of fish to build ships and use wooden paddles to imitate fins. According to legend, as early as the Dayu period, the working people in ancient China observed fish swimming and turning with their tails wagging in the water, so they put wooden paddles on the stern. Through repeated observation, imitation and practice, it was gradually changed to paddle rudder, which increased the power of the ship and mastered the means of capsizing. In this way, even in the rolling river, people can let ships sail freely.
Birds' wings have many special functions and structures, which make them not only good at flying, but also perform many "stunts" that are difficult for human technology to achieve at present. Hummingbird is a "helicopter" among birds. It can take off and land vertically and fly backwards. When sucking nectar, it does not stop on the flower like a bee, but hovers in the air. What a clever flight this is. It has become the dream of many aircraft designers to make vertical take-off and landing aircraft with hummingbird flight characteristics. Nature is beautiful, and we should protect it.
