Nature's Secret One.

On the edge of the Grand Canyon in Colorado, there is a Cape Prairie with a lot of deer on the prairie. Although the water and grass are abundant, the number of wild deer is always around 4,000. It was found that the grasslands were inhabited by natural predators of deer——— wolves and mountain lions.

so that the number of deer cannot be increased. So, from 1907, people began to fight to exterminate wolves and mountain lions. After 10 years of hard work, wolves and mountain lions have been beaten to the ground, and wild deer are increasing year by year.

By 1924 it had reached 100,000 heads. In the following two winters, the number of wild deer decreased dramatically. This is because there are too many deer and not enough grass to eat, and 60,000 deer are starving to death.

After that, the number of deer heads continued to decrease, and by the 40s, only about 10,000 remained; At this time, people were surprised to find that although there were fewer deer, the grass was still not enough to eat, because the development of deer in the 20s brought devastating damage to the grassland vegetation, and grass could not grow in many places. After many years, the grassland did not recover. In the grassland ecosystem, the deer eat the grass, the wolf eats the deer, and after the wolf dies, after the decomposition of microorganisms, its carcass becomes fertilizer and is absorbed by the grass.

In this way, a food chain is formed. In the past, how much grass grew on the grassland, how many deer were supported by these grasses, and how many wolves were raised by these deer, all had a certain range, maintaining relative stability and balance. However, after the wolf was eliminated, the balance was upset, and the entire grassland changed dramatically.

And once this change happens, there will be a chain reaction that cannot be reversed in a short period of time.

The Revelation of the Fish.

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 oars to imitate fins. Legend has it that as early as the Yu period, the ancient working people of our country observed the fish swimming and turning with the swing of their tails in the water, and they set up wooden oars on the stern of the boat. Through repeated observation, imitation and practice, it was gradually changed to an oar and rudder, which increased the power of the ship and mastered the means of making the ship turn.

In this way, people can make boats sail freely, even in rough rivers.

Hummingbird's revelation.

The tiny hummingbird is the "***" of birds, it can both take off and land vertically, and it can fly backwards. While sucking nectar, it does not rest on the flower like a bee, but hovers in the air. What a clever flight.

The creation of a vertical take-off and landing aircraft with the characteristics of the Hummingbird flight has become a dream dream of many aircraft designers.

Penguin's revelation.

Inspired by the penguins, a new type of car was designed, the "Penguin Polar Off-Road Vehicle". This kind of car is attached to the snow with a wide bottom and propelled forward with a wheel spoon, which not only solves the problem of polar transportation, but also can drive on muddy terrain.

Nature's inspiration to man.

Lu Ban made an umbrella based on lotus leaves. The electronic frog eye was invented based on the frog eye. According to the body of the whale"Streamlined"The steamship was invented.

Airplanes were invented according to the birds. The jellyfish ear storm detector was invented based on the downwind ears of jellyfish. Velcro was invented based on Xanthium.

Sonar was invented based on the positioning system of dolphinsThe main tube of the Beijing 2008 Olympic Games (named Bird's Nest) was built according to the structure of the Bird's Nest. 3.

According to the inspiration of the chameleon encountering danger and changing color to escape, people invented special military uniforms with different geographical environments.

The Revelation of the Fly.

The wings of flies (also known as balance sticks) are "natural navigators", and people imitate them to make "vibrating gyroscopes". This instrument is already being used in rockets and high-speed aircraft, and it has achieved autonomous driving. The fly's eye is a kind of "compound eye", which is composed of more than 30o0 small eyes, and people imitate it to make a "fly's eye lens".

Using it as a lens can be used to make a "fly's eye camera", which can take thousands of identical photos at a time. This.

In fact, nature has no inspiration、、、 just let us protect it Upstairs is off topic o( oha!

Nature tells us he's angry!

Human beings cut down indiscriminately against the laws of nature.

Farming, corporate discharge, overfishing, and so on.

Humanity has to pay for the mistakes it makes.

Environmental pollution is serious, and climate change is impermanent.

This is all part of the revelation that nature has given us.

1.We can hee at some of the laws that we have discovered in this nature, such as the sun rising in the east, and the revelation of these objective laws.

2.At the same time, we see that this natural animal is connected to the law of the jungle, and what efforts do humans need to make in the process of development? These are objectively associated with some of our own subjective thoughts.

3.At the same time, you can also write about how humans and nature get along well.

4.While the healthy and steady development of human beings, how to make nature can also develop better, some suggestions and ideas of enlightenment.

Biomimicists imitate the structure and function of jellyfish ears and design the jellyfish ear storm instrument, which quite accurately simulates the organs of jellyfish that sense infrasound waves. Installed on the foredeck of the ship, this instrument can cause the horn to rotate 360° to stop rotating when it receives the infrasound wave of the storm, and the direction it points to is the direction in which the storm is going; The readings on the indicator tell you the intensity of the storm. This instrument can make a forecast of storms 15 hours in advance, which is of great significance for the safety of navigation and fishery.
