For a better life, migrating geese, whether living in Asia, Europe or North America, travel back and forth from north to south every year and cross Qian Shan for a month or two. During this period, they are always led by experienced geese and fly in a line. There are usually only two kinds of flying arrays: the word "one" and the word "person". Although there are few moves, they are extremely efficient. For geese, with the word "one" and "human" flying technology, they have simply become "fighters" in "energy saving".

There is a simple reason. When the leading geese flap their wings, there will be an updraft at the tip of the wing. Although it is extremely weak, the goose will never waste it. The ones behind will immediately slide on this airflow and let the wings rest for a while. And the more geese there are, the easier it is to fly. But in this way, it is difficult for the leading geese without updraft. Fortunately, the geese implemented the "shift system", and everyone took turns to be the "leading geese".

In addition, this flying technology is also very beneficial for geese to defend against the enemy, take care of each other and avoid backwardness.

The scale undergoes thermal conversion.

Satellites can travel in space and stand the test of ice and fire. Because of its temperature control system, it looks like a shutter, which is a model using solar energy.

But in fact, this is a low-carbon skill "stolen" from butterflies. Moreover, in contrast, it is still the ability of butterflies. It turns out that there are countless scales hanging on their wings, one by one, like tiles, so small that they can only be seen clearly under a high-powered microscope. It is these scales that act as heat exchangers for butterflies, which can help them absorb and release heat and regulate their body temperature.

Whether the temperature is too high or too low, fragile butterflies will face difficulties. Fortunately, with these measures, they will "take a step forward" in due course. Whenever the temperature rises and the sun shines on the scales, the scales will automatically open to reduce the radiation angle of the sun, thus reducing the absorption of solar heat. When the outside temperature is too low, these scales will automatically shut down, allowing sunlight to directly shine on the scales, increasing the absorbed heat. This ensures that the butterfly can properly control its body temperature without "air conditioning" and "electric fan".

It's "green fart"

Don't talk nonsense, let alone fart, because it will pollute the environment! Cattle and sheep paid the price for their careless farting. It is said that their fart contains a lot of methane, which is a gas with far more destructive power than carbon dioxide. Therefore, researchers in some countries tie "canned food" to cattle and sheep for research, and some even plan to add garlic to feed.

For kangaroos living in Australia, they are not worried that they will encounter similar "tragic fate" like these "buddies". Because they only put "green fart", which means kangaroo fart does not contain greenhouse gases such as methane.

There is a simple reason. Kangaroo's stomach contains a special kind of bacteria, which not only does not produce methane, but also produces 1 acetate, a compound that improves the digestive system. It's just that scientists don't know where the bacteria come from, but I believe it's not far from the moment when the truth comes out. Scientists have extracted more than 200 kinds of bacteria from kangaroo stomachs and are studying them one by one.

Living in a hexagonal house

This is one of the most famous low-carbon animals-bees! Almost all bees in the world build their homes according to the same pattern, which is the hive. Beehives are composed of hexagonal small beehives arranged neatly. These beehives are the same size, each is a regular hexagon, each is surrounded by other beehives, and the two beehives are separated by a wax wall. The bottom of each hive consists of three identical diamonds. Some curious people measured the angles of these diamonds and found that their obtuse angles and acute angles were exactly the same as those calculated by modern mathematicians, namely 109 and 70 respectively.

Don't underestimate this kind of house. It is not only exquisite and applicable in structure, but also can withstand greater impact than other structures. Most importantly, it fully conforms to the material concept of low carbon and saving people to the greatest extent. In other words, bees build the largest hive with the least beeswax. The hexagonal "door" is only for bees with cylindrical bodies to enter and exit, so that they will not have extra space in the hive and will not feel crowded.

These guys are just a few representatives of low-carbon animals. In fact, in order to become a real low-carbon race, we humans should constantly learn from animals.
