The population of the Earth weighs a total of 287 million tonnes
The population of the Earth weighs a total of 287 million tonnes. This was estimated for the first time from British scientists.
The overweight people in the world are making 15 million tons, according to the calculations of the experts from the London School of Hygiene and Tropical Diseases. 3.5 million tons is the total amount of the weight of the people that are suffering from obesity.
For their calculations, the researchers compiled a table which ranked the countries according to World Health Organization’s (WHO) data on the average weight of their inhabitants. Older people on Earth weigh on average 62 kilograms, but in the U.S. this figure is one third higher.
There are differences between continents. For example, in North America, an average adult weighs 80.7 kg, while in Asia – only 57.7 kg.
According to the British scientists over 70 per cent of the inhabitants of North America are overweight. On the continent lives 6% of the world’s population, but the people there represent 34% of the world’s obese people. While Asia, for example, accounts for 61% of world’s population and has only 13% of the obese people.
The leadership of the United States in the list of “the most fat” countries had not surprised the scientists. But they remained stunned by the presence in the top 10 of most obese countries, places, such as Qatar, Croatia, Kuwait, Egypt.
According to Professor Ian Roberts, one of the authors of the study, this can be explained by the impact of the cars. One of the main factors in calculating the average mass of the inhabitants of every country in the survey is the volume of automobile emitted gases per capita. For experts there is a direct link between the amount of car exhaust and the average weight in the country. People are transporting themselves less by walking and more with cars, says Professor Roberts.
Among the “lightest” countries logically were ordered North Korea, Ethiopia, Eritrea and others. In this “light” group, however, was also Japan, leading scientists to believe that it is not necessarily in rich countries to have a lot of overweight people.
