If there were no crab, agriculture might not be what we are used to seeing today Crabs or Earthworms feed on birds, lizards, spiders, foxes and many large insects, but hardly any of us are aware of their widespread importance.
Normally no one is sympathetic to this animal that is hiding underground, but it can easily be called one of the most important animals in the world.
In 1881, Charles Darwin realized its importance. He said, “There is no doubt that no other animal has played a more important role than this simple creature in the history of the world.”
In the past, when the Egyptians saw that they brought the fertile soil to the land after the flood in the Nile, they started calling them ‘inferior God’. The fact is that without crabs, the soil would not be as we are accustomed to seeing, without soil the agriculture would not be possible.
Crabs are considered ‘environmental engineers’. Through their activities they are capable of changing the properties of the soil and creating a new environment for many other animals.
In this way, they provide facilities for other animals, including humans, that society does not value.
Improving soil texture
Let’s look at some examples. They improve the structure of the soil by making it a home for our residents. By making organic matter their food, these microscopes facilitate the work of microbes, and when they make them food, nutrients are produced for the plants.
Plants also thrive better where underground shrimp communities are thriving and balanced. Similarly, where there are insects, the crops are good.
Recently, a research paper has been published by scientists in the journal ‘Science’ which examines the presence of crabs around the world.
The research was conducted by 140 researchers from around the world, which reviewed crab data and environmental data from more than 7000 locations. The study was conducted in 57 countries of all continents except Antarctica.
Never before has it been possible to collect and analyze such large-scale data about these animals. Therefore, this research is by far the largest research on the global presence of crabs.
And the results from it are quite astonishing.
First of all, research has found that the global distribution of crabs is quite different from that of animals on earth. Their biological diversity and their abundance are higher in the tropics (temperate zone) than in the warmer regions.
This discovery will also force us to consider changes in environmental survival policies. For example, one of the data that is used to prohibit the protection of natural areas is to look at the biodiversity present.
So far, only animals on the ground have been counted to identify these locations and no attention has been paid to the animals living on the ground.
They are not the national animals of a country like the Panda and the eagle, but they are far more important in our ecosystem.
It is time for biological protection policies to include them and other living creatures in the soil to better protect biodiversity.
Climate change threatens crabs
The second finding was that the distribution of crabs globally depends on climatic factors such as rainfall and temperature. Therefore, the authors of the article are concerned that climate change could have an impact on these animal populations.
Since the effects of climate change vary from region to region, the impact on crabs cannot be predicted.
Some locations, such as completely frozen fields, may also benefit from some types of crabs.
But it can have severe effects on most populations of insects, which can cause them to disappear from some locations.
This can affect all the environmental services that humans can provide to humans while living behind a cache.
Readers should worry about the little animals that are as important to humanity as ever.
Soil is a hidden treasure in which the biodiversity present is very important to our environment.
