Every species that exists on the earth has its reasons and tasks in the ecosystem. So what are the mission and the purpose we live in the world?
The ecosystem on earth is exceptionally magical when it comes to balancing and adapting itself to the living environment. Regardless of species, it contributes to the natural ecological chain and plays an essential role in the whole process. From tiny microorganisms to giant species like elephants, from aquatic species such as fish and shrimp to birds flying in the sky, from predators like tigers to plants, everything There are reasons to survive.
People are also a creature on the earth and "unfortunate" we are the rulers, at the forefront of the food chain. However, the role of a man with the land is still quite obscure. Humanity leads the ecosystem, so is our part to protect lower-level species? But see what people are doing to earth mother.
The study found that 7.6 billion people accounted for only 0.01% of all species and accounted for 86% of the land area, but we destroyed 83% of wildlife and 50% of the Plants since human civilization formed. Over the past 50 years, about half of the animals on earth have been killed directly or indirectly from humans. Worse, 300 years of catching seafood make the ocean only a fifth of mammals.
In fact, the new bacterium is the most abundant form of the living organism in the world with 13% while plants make up 82% of the earth's life. All species from fish to animals make up only 5%.
If compared in quantity, fungi even 200 times more crowded than humans, bacteria multiply by 1,200 times and trees fold 7,500 times.
It is quite interesting that although killing most of the creatures on earth, human breeding is contributing a large part to some species. About 70% of the world's birds now belong to farms, about 60% of the current mammals are grazed by humans.
However, it is the development of the livestock sector that is destructive nature, leading to the 6th genocide risk of humans.
5 genocides in the history of the earth
- End-Ordovician: 443 million years ago
The ice age caused a dramatic drop in sea level by more than 100m due to the formation of ice blocks, which caused 60-70% of organisms, mainly living in the country to become extinct. After that, the disintegration of ice blocks began to form oxygen and the birth of new species.
- Late Devonian: 360 million years ago
A series of climate changes caused many lives in shallow waters to die. In fact, the creature of this period began to dry up and live mainly in these shallow waters, so about 70% of the world's animals were destroyed, including the very popular coral reefs. At that time.
- Permian-Triassic: 250 million years ago
The eruption of the Siberian volcanoes causes global warming, killing more than 95% of the world's organisms.
- Triassic-Jurassic: 200 million years ago
¾ of the creatures were wiped out by a series of eruptions and earthquakes, clearing the way for the formation of the dinosaur period.
- Cretaceous-Tertiary: 65 million years ago
Many theories suggest that the cause was that a meteorite explosion took place in Mexico and a series of other volcanic eruptions eradicated dinosaurs and many other animals, clearing the way for mammals, including people who dominate the earth.
