Natural selection, survival of the fittest.
That is, the death of inadaptability.
Just give an example.
At the beginning of the Industrial Revolution in the UK, the bark of trees near Manchester was light-colored. And those black moths that inhabit these trees are easy to eat.
They were found by birds, so the moths had little chance of surviving. After 50 years, due to industrial pollution, the moss in the woodland died and the bark turned black. This time, however, the light-colored moths that inhabit the trees became prey to the birds. As a result, the number of light-colored moths gradually decreased, while the number of dark-colored moths began to increase--- because they were not easy to see.

It's controlled by genes, it's that simple! My opinion.

Adaptation refers to the process by which organisms adjust to their environmental stresses. In order to be able to survive and reproduce better in a certain environment, organisms are constantly adjusted from morphological, physiological, developmental or behavioral aspects to adapt to the ecological factors and changes in a specific environment. The ecological adaptation of organisms to the environment can be summarized as:
evolutionary adaptation, in which organisms adjust their genetic composition to suit changing environmental conditions through a long process; Physiological adaptation, through physiological processes, adapts organisms to adapt to changes in climatic conditions, food quality and other environmental conditions; Adaptation by learning, organisms adapt to a variety of environmental changes through learning and behavior.
Adaptation can alter the range of tolerance of organisms to ecological factors. The various ecological factors of the natural environment are interrelated and mutually influential, so the adaptation to a specific set of environmental conditions must also show interrelatedness, and this set of synergistic adaptation characteristics is called adaptive suite.

The adaptation of organisms to their environment is universal. Every living organism now has a morphological structure, physiological characteristics or behavior that is adapted to the environment. This is the universality of the adaptation of organisms to the environment.
The materials and energy needed to sustain the life activities of living organisms must be obtained from the environment.
The environment has many impacts on living things. Organisms can only survive if they adapt to their environment. Organisms are able to influence the environment as well as adapting to it.
For example, transpiration from forests can increase the humidity of the air, which in turn affects rainfall. Plants such as cedar can absorb toxic gases, which can purify the air; Rats have a destructive effect on crops, forests and grasslands; Earthworms move in the soil, which can loosen the soil, improve the soil's aeration and water absorption capacity, and its excrement can also increase the fertility of the soil. It can be seen that organisms and the environment are mutually influential, and they are an inseparable and unified whole.

While adapting to the environment of Zen pants, living beings also influence and change the environment.
Adaptation of organisms to the environment: The adaptation of organisms to the environment is the process of survival of the fittest in natural selection, which promotes the continuous evolution of organisms, and the phenomenon of adaptation of organisms to the environment is prevalent in nature, and for every organism that exists today, it has the characteristics of adapting to the environment.
The influence of the environment of organisms: the relationship between organisms and the environment is mutually open, and organisms can not only adapt to the environment, but also affect the environment; Conversely, the environment also affects the growth and distribution of organisms.
Affect the atmospheric environment: plant transpiration increases air humidity, lowers air temperature, and affects precipitation. The leaves of some plants can absorb dust and toxic gases, which can play a role in purifying the air.
Affect the water environment: Red tide phenomenon caused by some tiny plankton causes harm to the water environment.
Affect the soil environment: Earthworms can loosen the soil and increase fertility.
Organisms and the environment interact with each other, and it is a long process. In this process, the environment is constantly changing, and so are living things, and the interaction between living things and the environment has created today's thriving biological world.
Ecological factors in the environment affect the life and distribution of organisms, such as the effect of temperature on the distribution of animals, polar bears. Effect of temperature on plants, coconut palms. These are environmental impact organisms. >>>More

It seems that I have to help you and give you a brilliant design: first, design in combination with life, for example, reduce driving, do more public transportation, keep low carbon, use less thin plastics, garbage classification, professional batteries, electrical appliances, green protection, bird protection, and beast protection, but these are all virtual and nonsense, and everyone will say. So when it comes to the second item, you're going to observe, or you're bragging, you're observing. >>>More
