Cyanobacteria: destruction and prosperity

  Looking into the vast universe, although we have worked hard for many years, the earth is still the only known planet that gave birth to life. However, billions of years ago, the environment of the earth was extremely harsh, at least quite unsuitable for human survival, until a type of organism changed it …
  The name of this type of organism is called cyanobacteria, and some people call it cyanobacteria, however It is neither an algae nor a bacterium, but another type of living organism with a simple cell structure. Today, they are still active in every corner of the planet. In early Earth, cyanobacteria, like other living organisms, were single-celled and hated oxygen. In fact, at that time, there was no oxygen on the earth. Compared with today’s oxidizing environment, it is a reducing environment. Oxygen is as terrible as toxic to cyanobacteria.
  However, some alternatives have been born in cyanobacteria, that is, some guys who can efficiently perform photosynthesis, which are faster and more efficient than the original photosynthesis of all creatures. But the by-product of this efficient photosynthesis is oxygen, which is the beginning of a tragedy and a great beginning.
  The scattered oxygen eliminated the iron and elemental sulfur, and killed those lives that could not adapt to the existence of oxygen. This is a bloody killing with oxygen as the medium. Those oxygen-resistant organisms that once dominated in the ancient times were slaughtered to the end of the pant and died. Cyanobacteria and other oxygen-resistant organisms are booming and quickly dominate.
  However, the sword finally pointed to cyanobacteria.
  Oxygen began to purge greenhouse gases such as methane in the earth’s atmosphere-the surface temperature of the planet began to drop rapidly. Finally, the glaciers covered the entire planet, from the poles to the equator. No matter whether they were resistant to oxygen, all living things were in trouble. The most tragic biological extinction in geological history occurred. After that, it was a long struggle and waiting of 300 million years.
  However, life finally survived. Greeting them is a bright future.
  In fact, cyanobacteria saved all lives, even if it was the creator of disaster.
  If there is no oxygen, this planet will not be able to give birth to such diverse life systems as today-the oxygen in the atmosphere supports all living organisms to perform efficient life operations through breathing, obtain energy, run on land, and swim in the ocean, Soar in the sky.
  If there is no oxygen, the planet will no longer be as blue as it is today-the ozone layer formed by oxygen at high altitude blocks ultraviolet rays and cosmic rays, not only protecting life, but also protecting the surface water. Otherwise, the energy from the universe will explode the water molecules, and the hydrogen produced therein will escape into the universe. Sooner or later, our planet will dry up like Mars and Venus, and the life that has been produced will also be silent.
  Today, cyanobacteria are still the most important oxygen contributor on the planet, accounting for half of the Earth ’s oxygen production, although they are unknown and unseen by the naked eye. However, the story is far from over. Another major contributor to contemporary oxygen, green plants, the photosynthetic structure in their cells, the chloroplast, was once also derived from cyanobacteria that co-occur in the cells.
  Cyanobacteria, through the life process of creation, personally destroyed an era, and at the same time is the cornerstone of another era. Creation, a double-edged sword between destruction and prosperity, composes a magnificent evolutionary epic.
