The impact of pesticides on human health and natural ecosystems is what Carson began to assemble data about. In employing chemical pesticides, Carson argued for much greater sensitivity and care to the environment. As a preferable alternative for pest control, Carson further urged natural biotic agents. As cancer and other ailments took their toll, Carson's health deteriorated while her mother died in 1958. In 1962 the book Silent Spring was published. However, it provoked a lot of criticism. Rachel Carson was born in 1907 and never married. Since Carson called into question the idea of science as progress, she evoked a huge backlash.

Rachel Carson was an author who's childhood interest in nature led to a career as a marine biologist with the U.S. While penning three books on the ecology of the sea, she was also finding her voice as a writer. Her confidence in the fact that nature was immune to human action has been shook by the dramatic bombings in 1945 of Hiroshima and Nagasaki. The assumption that for human welfare, science always held positive outcomes began to be questioned by Rachel Carson. The environment introduced pesticides and other toxins, which caused the skepticism of science always having positive outcomes for human welfare to take shape in the name of progress. Silent Spring was a project that Carson took on due to the death of birds in her friend's yard following aerial spraying for mosquito control.

In many major cities, a pall of air pollution was created by the global spread of modern industry. Face masks were frequently worn by traffic police in Tokyo during the 1970s. It was estimated in 2002 that 35,000 people in Mexico City were killed from air pollution. By the late 1980s, about half of the Soviet Union's rivers were severely polluted from industrial pollution. The earth is protected by the ozone layer from excessive ultraviolet radiation. Global warming was the most intractable and critical environmental transformation. The atmosphere had begun to be warmed significantly due to the vastly increased burning of fossil fuels, which occurred by the end of the twentieth century.

The energy resources available to our species was added to by natural gas, hydroelectricity, and nuclear power. The production of goods and services was immensely increased by modern science and technology. The natural order was always altered by human activity, but now the scale of that impact assumed geological and global proportions. The doubling of cropland was led to by the growing consumption of the rich and the growing numbers of the poor, which also led to dramatic increases in the rate of erosion. At the hands of humankind, massive species extinctions is happening. In environments shaped by human action is where 90 percent of all plant activity now occurs.

Humankind's growing ability to alter the natural order has been the most pronounced out of all distinctive features of the twentieth century. The Anthropocene or the Age of Man is what scientists began to refer to the current era as. The lasting impact of human activity on the planet is what this informal term has called attention to. In 2012, the world was left with over 7 billion people, in comparison to 1900 when the world had about 1.6 billion people. Death rates and Green Revolution technologies were lowered by medical and sanitation advances. The new ability of humankind to tap the energy potential of fossil fuels lay in a second cause of environmental stress. This led to oil in the twentieth century and coal in the nineteenth.

Religious practice and belief declined sharply in Britain, the Netherlands, France, and the Soviet Union. Those trends that involved the further spread of major world religions were the far more prominent trends of the last century. In this most recent century, religion played an unexpectedly role. As transregional cultures Christianity, Buddhism, and Islam have been spreading far beyond their places of origin. In the West, Buddhist ideas and practices such as yoga and meditation found a warm reception. Perhaps 7 to 8 percent of China's population claimed allegiance to the faith; some 84 to 96 million people did so by the end of the twentieth century. Asia, Latin America, and Africa is where by the early twenty-first century, Christianity found some 62 percent of its adherents. A certain religion was planted solidly in the West by millions of migrants from the Islamic world. In the United States, both African Americans and European Americans engaged in Islamic practice.

From a value of some $57 billion in 1947, world trade skyrocketed to about $16 trillion in 2009. Goods from every part of the globe were stocked in shelves of department stores and supermarkets around the world. In more than 100 countries, twinings of London marketed its 120 blends of tea, and in 180 countries the Australian based Kiwi shoe polish was sold. Components from China were reportedly included in about 70  percent of Walmart products in 2005. With manufacturing facilities in at least eighteen countries, Toyota replaced General Motors as the world's largest automaker the following year. In developing countries, tax breaks, cheap labor, and looser environments were taken advantage of from companies in rich counties after 1960.

The acceleration of economic was contributed to by technology. The communication infrastructure for global economic interaction was provided for by fiber-optic cables and the Internet. Population growth further fueled globalization in the developing countries as dozens of new nations entered the world economy. Neoliberalism is known as economic globalization taking shape in the 1970s and after. If poor countries were to qualify for much-needed loans, free market and pro-business conditions were imposed by powerful international lending agencies. Such unrestricted global capitalism was furthered by the collapse of state-controlled economies of the communist world. By the end of the twentieth century, communism collapsed.

Two Iranian Muslim dolls named Sara and Dara, were made by Masoumeh Rahimi to counteract the negative influence of Barbie and Ken. While looking to their loving parents for guidance, Sara and Dara helped each other solve problems. The creation of Sara and Dara portrays resistance to the cultural values associated with Barbie and Ken. Both Sara and Barbie were manufactured in China. By the 1990s, globalization was known as a process of accelerating engagement among distant peoples. After World War II, global interaction quickened its pace and deepened its impact. What occurred in the second half of the twentieth century is globalization, and it continued into the twenty-first century. This process has been seen by many as practically unstoppable, almost natural, and certainly inevitable. As many states turned inward, investment, international trade, and labor migration dropped sharply. The foundation for postwar globalization was laid by a set of agreements and institutions in 1944 at a conference in Bretton Woods, New Hampshire.

Within the Muslim world, Islamic faith and justice demand that anti-Islamic governments not be allowed to survive. Any nonreligious power is considered to be an atheistic power, which is the tool of Satan. All governments that do not rest purely on Islamic principles must be overthrown. Carrying the Islamic political revolution to its final victory is the duty of all Muslim countries, and of all Muslims in the world. Religious schools within Muslim countries have been created by western missionaries carrying out secret plans drawn up centuries ago. Such missionaries tried to turn Muslim children into Christians or atheists. The Jewish people are at the source of all anti-Islamic libels and intrigues current today.

The hat, also known as the customary headdress of the whole civilized world, showed that no difference existed in the manner of thought between the Turkish nation and the civilized mankind. In 1979 an Islamic revolution in Iran brought to power a government committed to Islamization of public life. That revolution had been led and inspired by an Iranian religious scholar named Ayatollah Khomeini. Ayatollah Khomeini was the supreme leader of Iran during the 1980s. Those who fight against colonialism are in the school of Islam.

After World War 1 modern Turkey emerged from the Ottoman Empire under the leadership of Mustafa Kemal Ataturk. Ataturk explained and justified certain policies regarding the removal of Islam from any significant role in public life in a speech he delivered in 1927. Such a speech went against much of Islamic thinking. Ottoman rulers wanted to lead and govern the entire Islamic world in one dafter uniting it. A state must be compelled to act justly and impartially toward all of the different religions. Respecting freedom of conscience and opinion is its obligation. Freedom of religious opinion is included in the Muslim religion. Breaking Islam into ruins, the party of Mustapha Kemal will make Islam's citizens into unbelievers after having abolished the Caliphate.

The struggle for independence of decolonization caused nation-states to triumph over the empires that had structured much of the world's political life throughout the early twentieth and nineteenth centuries. It mobilized millions of people, sometimes thrusting them into violence and warfare. As permanent features of the world's political landscape, European colonial empires in Asia and Africa appeared in 1900. The age of African independence took place from mid-1950s through mid-1970s as more than fifty colonies emerged into the bright light of freedom.

Nelson Mandela, South Africa's nationalist leader, tried to overthrow the apartheid government of his country in 1964. He spent the next twenty-seven years in prison. He was permitted to write and receive one letter every six months, and to have one visitor a year for thirty minutes. He was released from prison in 1990, when he concluded his first speech as a free person. Blacks and whites were able to vote for the first time in 1994, when South Africa held its election. Mandela was South Africa's first black African president due to the outcome of that election.

Joseph Stalin was born in Georgia in 1878 with a brutal and abusive father. Stalin joined the Bolsheviks, who were led by Lenin. In 1917, he also played a modest role in the Russian Revolution. Stalin rose to the dominant position in the Communist Party after Lenin's death in 1924. Stalin appeared and gave a report on the achievements of the country's plan for overall development in January 1933. That plan took place from 1928-1932, which was when Stalin would rise to the position of supreme leader of the Soviet Union.
