The study, published in the journal Proceedings of the National Academy of Sciences of the United States of America, highlights the impact of humankind on biodiversity and wildlife on Earth, even though people represent only a small fraction of all life on the planet.
On the day of the publication of the study (21 May 2018), the 7.6 billion people on Earth represent only 0.01 per cent of the world’s population, but this species remains a major influence on other forms of life. Since the beginning of civilization the human race resulted in the loss of 83 percent of all wild animals and 50 percent of all plants. At the same time cattle that are grown for human consumption accounts for a large proportion of animals on Earth, which means that the natural harmonious balance between the types falling, while the production of animals for food is increasing.
The study also showed that 70 percent of all birds on Earth farmed poultry, only 30 percent are illegal. The percentage of wild mammals was very small; 60 percent of mammals on Earth is livestock (mainly cattle and pigs), 36 percent of the people and only four per cent of mammals on the planet are wild animals.
In addition, the whaling industry, which has been operating for 300 years, is responsible for 80 per cent decline in marine life.
In general, 82 percent of life on Earth consists of plants, 13 percent of bacteria, and only five percent of life on Earth represent the animals.
“I hope that this will give people a perspective on the dominant role played by the mankind on Earth,” the Guardian said Professor Ron Milo with Israeli Weizmann Scientific Institute, who led the work. According to media publications Milo said that due to the negative impact of meat production on the environment are choosing predominantly vegetarian diet. “This is certainly surprising, our disproportionately on Earth. When the daughters putting together a puzzle, is it normal elephant next to a giraffe and rhino. But if they try to give a more realistic sense of the world would be a cow next to cows and then the Chicken. “
In wildlife films, we see flocks of birds of all kinds in huge numbers, but when we did the analysis, we found that [many] more domesticated birds, ”continued Milo, who later added that he was surprised that his work the first such global study of biomass.
A second report published last year states that in the last 50 years alone, about half of the animals on Earth have disappeared due to industrialization.
However, raising livestock is an unsustainable method of feeding the world, according to a report released earlier this month. The report states that the food industry could feed many more people if it grew plants instead of livestock.
