Working children

Child labour is one of the problems that many countries face , there are various causes that drive children to work some of them drop out of school in order to help their poor or sick parents others have to work because they are orphans. In addiction some parents are ignorant they think education is a waste of time .

Working children face a tough life; in factories and mines they work in bad conditions no fresh air, long hours they may be injured

Terrorism

Terrorism is a term used to describe violence or other harmful acts.they are classified terrorism into six categories.Civil Disorders.Political Terrorism .Non-Political Terrorism.Quasi-Terrorism.Limited Political Terrorism .Official or State TerrorismTerrorist attacks are often targeted to maximize fear and publicity. They usually use explosives or poison, but there is also concern about terrorist attacks using weapons of mass destruction. Terrorist organizations usually methodically plan attacks in advance, and may train participants, plant "undercover" agents, and raise money from supporters or through organized crime. Communication may occur through modern telecommunications, or through old-fashioned methods such as couriers.The context in which terrorist tactics are used is often a large-scale, unresolved political conflict.

Racism

Racism or racialism is a form of race , especially the belief that one race is superior to another. Racism may be expressed individually and consciously, through explicit thoughts, feelings, or acts, or socially and unconsciously, through institutions that promote inequality between races. In the 19th century many legitimized racist beliefs and practices through scientific theories about biological differences among races. Today, most scientists have rejected the biological basis of race or the validity of "race" as a scientific concept. Racism, then, becomes discrimination based on alleged race. Racists themselves usually do believe that humans are divided into different races.

There are two main definitions of racism today. One of them states that racism is dicrimination based on alleged race, the other - newer - one states that racism has started to include also discrimination based on religion or culture

Air pollution

is a chemical, physical (e.g. particulate matter), or biological agent that modifies the natural characteristics of the atmosphere. The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. Worldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease. Enforced air quality standards, like the Clean Air Act in the United States, have reduced the presence of some pollutants. While major stationary sources are often identified with air pollution, the greatest source of emissions is actually made up by mobile sources, mainly the automobiles. Gases such as carbon dioxide, which contribute to global warming, have recently gained recognition as pollutants by some scientists. Others recognize the gas as being essential to life .

A revolution

A revolution (from Late Latin revolutio which means "a turn around") is a significant change that usually occurs in a relatively short period of time. Variously defined revolutions have been happening throughout human history. They vary in terms of numbers of their participants (revolutionaries), means employed by them, duration, motivating ideology and many other aspects. They may result in a socio-political change in the socio-political institutions, or a major change in a culture or economy. Scholarly debates about what is and what is not a revolution center around several issues. Early study of revolutions primarily analyzed events in European history from psychological perspective[citation needed], soon however new theories were offered using explanations for more global events and using works from other social sciences such as sociology and political sciences. Several generations of scholarly thought have generated many competing theories on revolutions, gradually increasing our understanding of this complex phenomenon.

Globalization

Globalization refers to increasing global connectivity, integration and interdependence in the economic, social, technological, cultural, political, and ecological spheres. Globalization is an umbrella term and is perhaps best understood as a unitary process inclusive of many sub-processes (such as enhanced economic interdependence, increased cultural influence, rapid advances of information technology, and novel governance and geopolitical challenges) that are increasingly binding people and the biosphere more tightly into one global system.

There are several definitions and all usually mention the increasing connectivity of economies and ways of life across the world. The Encyclopedia Britannica says that globalization is the "process by which the experience of everyday life ... is becoming standardized around the world." While some scholars and observers of globalization stress convergence of patterns of production and consumption and a resulting homogenization of culture, others stress that globalization has the potential to take many diverse forms.

Water pollution

Water pollution is a large set of adverse effects upon water bodies such as lakes, rivers, oceans, and groundwater caused by human activities. Although natural phenomena such as volcanoes, algae blooms, storms, and earthquakes also cause major changes in water quality and the ecological status of water, these are not deemed to be pollution. Water pollution has many causes and characteristics. Increases in nutrient loading may lead to eutrophication. Organic wastes such as sewage impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole eco-system. Industries discharge a variety of pollutants in their wastewater including heavy metals, organic toxins, oils, nutrients, and solids. Discharges can also have thermal effects, especially those from power stations, and these too reduce the available oxygen. Silt-bearing runoff from many activities including construction sites, deforestation and agriculture can inhibit the penetration of sunlight through the water column, restricting photosynthesis and causing blanketing of the lake or river bed, in turn damaging ecological systems.

right of women

Nowadays we take it for granted that women have the same rights as men before the first world war few people believed this. As far as work was concerned there were jobs wich were regarded as women`s jobs and other wiche were regarded as men`s jobs. Women`s jobs were generally lower paid as men`s. Men did almost all the heavy jobs in industry or in transport. Women had jobs like dress-making,cleanning or worked as servants. Women`s main role was as being to raise childeren and look for their home. Women were not expected to take position of leaderschip. Women were not even allowed to vote in elections.

Before the war some women had been struggling to achieve greater equality with men. The most famous of these had been the suffragettes who stagged a violent campaign against the govervment from 1905 to 1914 trying to achieve the right to vote.however, at the outbreak of war, the were still no near to success. Many men argued that women were unsuited to such responsibility that women could not be trusted to vote sensibly that women should not concern themselves with such male

pollution

Nowadays, technology has brought many conveniences to facilitate our life.However,these same advancements in technology and science have caused some dangerous problems. The most hazardous of all of them is pollution.
Our land, air and water are all polluted. Perhaps the most serious threat to our planet is the loss of the ozone layer and the warming of the earth’s atmosphere which are due to carbon dioxide emissions from factories. Besides, the chemicals we use for cleaning and chemical wastes from factories go into our water systems and pollute the water we drink and the fish we eat. They also kill much of the wildlife we need for our food.
In conclusion, these problems are growing daily because people don’t want to change their lifestyle. People need to be educated so they will stop damaging our planet.
Furthermore,governments should take actions to prevent individuals and companies from harming their environment.
