The report says that the world s population will reach 7 billion by 2012, is it true? Please, thank

Statistics show that the world's population reached 1 billion in 1800, 2 billion in 1930, 3 billion in 1960, 4 billion in 1974, 5 billion in 1987 and 6 billion in 1999. According to the French National Institute for Demographic Research, the world's population exceeded 6.5 billion on December 19, 2005, and is expected to exceed 7 billion between 2012 and 2013. The world's population is expected to reach between 9 billion and 10 billion by mid-century.

Scientists have previously estimated that the Earth could support between 10 billion and 15 billion inhabitants at most. If population growth is not controlled in a timely and effective manner, the ideal of sustainable human development is likely to be difficult to realize. A study published by the United Nations in March 2005 found that the continued growth of the world's population and the expansion of economic activity over the past 50 years have put enormous pressure on the Earth's ecosystems.

Human activities have had a negative impact on 60% of the planet's grasslands, forests, agricultural croplands, rivers and lakes. In recent decades, one-fifth of the planet's corals and one-third of its mangrove forests have been destroyed, animal and plant diversity has rapidly declined, and one-third of species are on the verge of extinction. The combination of population growth and other factors has posed a serious challenge to human society as a whole.

In the case of water resources, for example, at least 1.1 billion people currently lack access to safe drinking water, and 2.6 billion people lack access to basic sanitation. In the face of heavy population pressure, the common ideals of mankind, such as economic development, social progress and environmental protection, are under great threat. Population issues concern every member of the "global village", and developed countries are no exception.

The U.S. population exceeded the 300 million mark on the 17th. The rapid growth of the U.S. population and its above-average per capita consumption of resources and energy have raised questions about the American path of development. Some other developed countries are also experiencing negative population growth and social ageing.

All this means that both developing and developed countries need to attach great importance to the population issue and establish a scientific population development strategy suited to their national conditions.

With a population of 6.5 billion, it is only a matter of time before 7 billion is expected.

A: In 2011, the world's population exceeded 7 billion.

Population growth can promote the division of labor and technological progress, and has a positive effect on economic development. At present, the most populous countries in the world are concentrated in Asia, namely China and India, and it is expected that India's population will surpass that of China within this year.

In 2010, the world's population totaled 100 million. Then 1.9 billion people is 27% of the world's population

In 2000, the world's population reached 100 million, and the population of Asia reached 100 million, accounting for about 60% of the world's total population, of which there are six countries with a population of more than 100 million, namely, China, India, Indonesia, Riben, Bangladesh, and Pakistan

Analysis: In 2000, the world's population reached 100 million, and the population of Asia reached.

60 + 60x1 6 60 divided by 6x(6+1) units are all molded and slippery is 100 million hopes.

Solution: Suppose the world's population will reach x billion in 2017, x = 1/2).

x = 6 x = A: The world's population will reach 100 million in 2017.

International ** special article: According to the Swiss "Neue Zurich Zeitung" 28**, the German World Population Association (DSW) released a set of statistics on December 28 on the upcoming end of 2010, which shows that the world's population will exceed 7 billion in 2011.

According to data released by the German World Population Association, the total world population is expected to reach 6,934,196,000 at 0:000 on January 1, 2011, with the African continent growing the fastest.

The first meeting pointed out in Hannover, Germany on the 28th that the earth's population will increase at a rate of people per second, and by mid-2011, the total number of the world's population will exceed 7 billion; By 2025, the world's population will reach 8 billion people; By 2050, the global population will increase by another 2.2 billion. Population growth in developing countries is particularly rapid, with 82 per cent of the world's population, or 5.7 billion people, currently living in developing countries and regions. Countries in the African continent are growing at the fastest rate in the world.

By mid-century (2050), the total population of the African region will be close to 2 billion, twice as many as it is today. Rapid population growth has exacerbated problems in Africa's poverty, education and health systems. At present, most countries in Africa are unable to provide sufficient food to their populations.

According to Renate Baehr, vice president of the German World Population Association, "At this rate, the heavy burden of people will make Africa poorer and poorer. If poverty and hunger are to be reduced, family planning, health care and the provision of modern contraceptives are needed. ”

It will reach 7 billion, with a current annual growth of 78 million.

On October 30, 2011, at 24 o'clock London time, the first round of the World Fierce Games was clocked, showing 6999938456 people available.

In the early hours of October 31, 2011, a baby was born in the Philippines, becoming one of the symbolic 7 billion members of the world.

According to the United Nations Population**, it took more than a century for the world's population to grow from 1 billion to 2 billion, from 2 billion to 3 billion in 32 years, and since 1987, the number of branches has increased by 1 billion every 12 years. This pace has slowed down because of China's implementation of family planning. By 2025, it will reach 8 billion.

If you vaguely estimate it, it should be less than 7.1 billion in 2012 and less than 7.2 billion in 2013.

In 1804, the world's population was only 1 billion, in 1927 it grew to 2 billion, in 1960 it reached 3 billion, in 1975 it reached 4 billion, in 1987 it rose to 5 billion, and on October 12, 1999, the world's population reached 6 billion. On October 31, 2011, the population of the World Sky Marking Hall reached 7 billion.

At this rate, the world's population should now be 100 million.
