Recommended: Human population growth
During the first 2 million or so years of its history the human population was a minor element in the world ecosystem, with at most 10 million members. In the New Stone Age, less than 10,000 years ago, the number of humans began to increase more rapidly. The rough equilibrium maintained before Neolithic times gave way when the human population developed agriculture and animal husbandry and no longer had to spread out in search of game. With the abandonment of a hunting-gathering way of life and the rise of permanent settlements and eventually cities, the human population underwent dramatic growth. By the beginning of the Christian era it had reached 250 million, and by 1650, half a billion. Growth of population during 20th century was very rapid.
In 1994 the total world population was estimated at about 5. 6 billion people. It increased nearly by 4 billions of people during past 100 years. The most significant world trend is that death rates are currently falling in poor and rich countries alike, while birthrates remain high in most poor countries and low in most rich ones. Exceptions are the generally higher death rates of Africa and the high birthrates of the rich oil-producing countries.
The most populous countries, in descending order, are China, India, the United States, Indonesia, Brazil, and Russia. The U.S. population totaled about 260. 8 million in 1994.
In the 1990s about 4. 1 million children were born annually in the United States, and more than 2. 1 million persons died yearly. The greater number of births is due in part to a fertility rate that has increased by nearly 20 percent since the mid-1980s. International immigration, both legal and illegal, is another major element in U.S. population growth.
Legal immigration has recently amounted to about 1 million per year; illegal immigration is thought to be several hundred thousand. In China, the world's most populous country, the 1994 population was estimated at nearly 1. 2 billion, more than double the 1953 census population of 584 million in mainland China. China's annual increase has been estimated at 1. 1 percent annually. India's population of more than 911.
6 million people (1994 est.) is increasing faster than that of China, and if present trends continue, it will soon catch up with or surpass China. Since the disintegration of the USSR, Indonesia and Brazil are now the fourth and fifth most populous countries, with 1994 estimated populations of 199.
In 1900 the total population was 40 million. The population of England had risen at a rapid rate since 1825. In Scotland and Wales population was also rising but more slowly than England. The population of Ireland had actually fallen owing to a dreadful famine and the emigration that followed it. In England about 75 per cent of people lived in towns.
Some people believe that immigration in the 1900’s was a good thing, however, they would be wrong. The United States government should have restricted the immigrants around that time. Some reasons are the population, the taking of new jobs and lowering wages, and diseases spreading quickly. These all factored importantly into why they should not have been allowed in.
Among world regions, the number of unauthorized immigrants from Asia, Central America and sub-Saharan Africa rose between 2009 and 2014. The number of immigrants from Mexico has steadily declined since 2007, the first year of the Great Recession, but Mexicans remain more than half (52%) of U.S. unauthorized immigrants. ”(Jeffrey Passel). “Population growth is influenced by three factors: mortality (the death rate, which has been steadily decreasing in the U.S.), birth rates or fertility (children per woman) and net immigration (immigration minus emigration). “ (USPS).
Son of a poverty-stricken shoemaker, raised in a backward province, Joseph Stalin had only a minimum of education. However, he had a burning faith in the destiny of social revolution and an iron determination to play a prominent role in it. His rise to power was bloody and bold, yet under his leadership, in an unexplainable twenty-nine years, Russia because a highly industrialized nation. Stalin was a despotic ruler who more than any other individual molded the features that characterized the Soviet regime and shaped the direction of Europe after World War II ended in 1945. From a young revolutionist to an absolute master of Soviet Russia, Joseph Stalin cast his shadow over the entire globe through his provocative affair in Domestic and Foreign policy.
During World War II alone, Joseph Stalin killed an estimated 20 to 60 million people. Born in the late 1870s, Stalin began his rise to power at 43, and by 45 had betrayed Vladimar Lenin to eventually become the leader of the Soviet Union. Stalin was a cruel man, even killing an artist for not potraying him as he wanted to be. He also made considerable use of the Communist International movement in order to keep other Communist parties pro-Stalin and pro-Soviet. Stalin, today, is seen as one of the most sadistic leaders in the past century, even surpassing Adolf Hitler to some people. Joseph Stalin is the man who turned the Soviet Union from a backward country into a world superpower at unimaginable human cost.
Thousands of animals are put to sleep each year due to not having any available homes for them to be adopted. According to Jennifer Sexton and Tom Warhol in Domestic Animal Overpopulation, “The average female cat can produce two litters of six kittens per year, a female dog can produce one litter of six or more puppies per year, making pet overpopulation a significant problem.” Animal overpopulation is costing money and you can help the pets with spay and neutering programs. A new solution is mandatory contracts for breeders and spay and neuter programs. This paper will talk about spay and neuter programs, contracts for breeders, and why some people don’t think animal overpopulation is a problem. Thankfully there are solutions to this issue of animal overpopulation.
12,000 years ago, the discovery of agriculture triggered such a change in society and the way in which people lived that we now call this important era in time the “Neolithic Revolution.” Traditional hunter-gatherer lifestyles were cast away in favor of more permanent settlements and a reliable food supply. Agriculture helped form cities and civilizations, and because crops and animals could now be farmed to meet growing demand, populations skyrocketed from around five million people 10,000 years ago, to more the more than seven billion people that walk this earth today.1
Stalin’s hunger for power and paranoia impacted the Soviet society severely, having devastating effects on the Communist Party, leaving it weak and shattering the framework of the party, the people of Russia, by stunting the growth of technology and progress through the purges of many educated civilians, as well as affecting The Red Army, a powerful military depleted of it’s force. The impact of the purges, ‘show trials’ and the Terror on Soviet society were rigorously negative. By purging all his challengers and opponents, Stalin created a blanket of fear over the whole society, and therefore, was able to stay in power, creating an empire that he could find more dependable.

Joseph Stalin came to power in 1924 after the death of Lenin even though Lenin himself had discouraged him as his successor. Stalin’s regime was latent with economic stagnation, political repression, human rights violations, and competing nationalities. Regardless of these various problems Stalin was able to sustain the Soviet Union and develop it into a dominant world power. His ability to maintain power and stability was a result of the promotion of social, economic, cultural, and political systems that increase Russian patriotism and unified the various nationalities.
Joseph Stalin became leader of the USSR after Lenin’s death in 1924. Lenin had a government of abstemious communist government. When Stalin came into government he moved to a radical communist society. He moved away from the somewhat capitalist/communist economy of Lenin time to “modernize” the USSR. He wanted to industrialize and modernize USSR. He had overworked his workers, his people were dying, and most of them in slave labor camps. In fact by doing this Stalin had hindered the USSR and put them even farther back in time.
China has 3.748 million square miles (or 9.707 million square kilometers). As a whole, China only has a population density of 139.6 people per square kilometer, or 363.3 people per square mile. Due to the large area of land, this results China to has a huge population.
Italy has the fifth-highest density of population at almost 500 people for every square mile. With a 2009 estimated population of 60.3 million people, Italy ranks 23rd worldwide—just behind the United Kingdom and France. The majority of the populace is Italian with a very small minority of migrants, but this has started to change due to a very low birthrate. The birthrate in Italy is 9.18 births for every 1,000 deaths; ranking the country at 209 in the world.
Around 60,000 to 70,000 years ago the human population nearly became extinct. The population went from around 2 million people to only around 3,000 people. Scientists think this was thanks to the combination of a super-volcano erupting and the ice-age.
Overpopulation is a growing problem all over the world. This is a very important environmental issue and needs to be dealt with. This environmental problem is affecting many countries in the world, but mostly the poor and impoverished countries that don’t have the resources to help deal with these issues. It also affects the environment like plants animal life and air quality. When the population of people expands we need more natural resources from the environment, so we consume more then we can produce. This leads to the lack of resources in many areas. When expanding we create a lot of pollution in the air, water, and land. The pollution affects many humans health. Overpopulation is doing more harm than any other environmental issue. Overpopulation also causes many of the other issues we are dealing with. This is very dangerous to not only us humans but the planet. Even though many wealthy countries are not affected by this overpopulation, I feel like they should help the cause. There is always two sides to an issue like this. Some people don’t think that overpopulation is a big problem and the ones who say it is an issue that needs to be dealt with.
