How much is your share of earth’s resources? .. surprising Statistics and figures
There are many statistics and figures that are related to the world population. There is certainly a direct and inverse relation between this number and the economy, standard of living and production, per capital income and land, as well as water, food and many other things that are affected by the increase or decrease of population growth.
The world’s population, which is constantly growing at present, is 7,653,447,234, distributed throughout the world. China is the number one country with a population of 1,416,430,798, India is second with 1,357,793,785, and the United States third. In seventh place, Nigeria, with a population of 197,142,130.
While Egypt is ranked first in the Arab countries and 14th in the global list in terms of population, which is 99,836,482, and it is expected that by 2025, the world population will be more than 8 billion people, and in about 2040, may reach 9 billion, By the year 2100 may reach 11 billion people.
The land area is 510,100,000 km² and the average land area is 0.07 square kilometers per person. It is certainly a very large area, but this measurement is for the entire area of the land whether inhabited, uninhabited, livable or unfit. Area erosion especially with the melting of Arctic ice, and Greenland occupies the first place in terms of per capita area of about 37 square kilometers.
While Mongolia comes in second place with half a square kilometer per capita, and it is clear that the largest difference between the first and second places, while the first Arab countries on the list is Libya, where the per capita 0.28 square kilometers.
Water accounts for 70% of the land area, but unfortunately only 3% of that amount is suitable for drinking and human use. It represents fresh water in rivers, lakes, wells and other freshwater sources on the earth. To 1% only because 2% of the above mentioned ratio is frozen in the North and South Poles.
According to this, the amount of fresh water on the surface of the earth is 10,633,450 cubic kilometers, and therefore the per capita share of it is up to 0.0015 cubic kilometers, equivalent to one and a half million cubic meters should be used throughout his life, the equivalent of one billion and 500 million liters, A very large amount for the average natural consumption of a natural person in 60 years, which is 4 million liters and about 300 thousand.
But in the case of the equitable distribution of water, but we all know that there are areas in which the freshwater is significantly less than the needs of the individual, while there are places in excess of the need, for example, in Iceland, the highest state of the world per capita 520,000 thousand cubic meters, Kuwait has a per capita share of 0% where it relies entirely on desalination.
It is known that the cultivated area decreases over time, as the figures show. In 1960, the per capita share was about half a hectare, equivalent to a quarter of a hectare, but that area declined by about half in 1990 to about one quarter of a hectare, Which is equivalent to 18 carats and is currently 12 carats and is expected to reach 10 carats in 2025.
This is certainly a very bad indicator of the decline of food, which depends on the existence of a large and essential crops. It is worth mentioning that the most countries with areas planted according to the world statistics is China with an area of 5 million square kilometers, followed by the United States of America with an area of 4 million square kilometers , While the first Arab countries, Saudi Arabia is ranked 12th in the world with an area of one million and 700 thousand square kilometers.
While Australia occupies the top place with the highest share of the cultivated area, followed by Kazakhstan and Canada and the first Arab countries in that list appear in the twenty-fifth place is Sudan.
Spending on education worldwide
There is no doubt that education is important and that all nations seek to develop it because it is the locomotive that draws this nation forward, and education is measured by the benefit of it. Many of the funds may be spent in the field of education, but this does not lead to the development of society. We note that spending on education has increased significantly in the last period, reaching almost 5% of income worldwide.
While the lowest spending rate in 2003 was 4% of the world’s national income. This expenditure is between 4 and 5%. There is certainly a difference between countries. However, according to the latest statistics published in 2017, Britain is the best nation in terms of education, even though it spends $ 2.6 trillion on it, a big difference from the United States, which is in second place.
Where it spends $ 18 trillion dollars at $ 57 thousand per person, while Canada comes in third place, and the first Arab countries that appear on the list is the United Arab Emirates, which comes in the 33rd place.
