Greenhouse gasses - Essay Example Some greenhouse gases originate from natural sources. Typical, evaporation adds water vapor into the atmosphere. Animals release CO2 when they breathe, or respire while methane is released from some low-oxygen environs naturally, such as swamps. In the other hand, nitrous oxide is formed by certain processes in water and soil. Volcanoes - both under the ocean and on land - release greenhouse gases, hence periods of high volcanic activity level tend to be warmer. From the time of the Industrial Revolution in the late 1700s to early 1800s, mankind have been releasing large amounts of greenhouse gases to the atmosphere (King, 2010). That amount has rose steeply in the previous century. Greenhouse gas emissions augmented by 70% between 1970 and 2004. CO2 emission, the most significant greenhouse gas, rose by around 80% during that time. The quantity of atmospheric CO2 today far exceeds the normal range seen over the previous 650,000 years (Steinberg, 1998). Big amount of the CO2 that human being put into the atmosphere originates from burning fossil fuels. Vehicles, trucks, trains, machinery, and planes all combust fossil fuels. Most electric power plants do, also. Another way humans discharge CO2 into the atmosphere involves by cutting down trees, because trees hold large amounts of carbon through photosynthesis. People increase methane to the atmosphere by livestock farming, landfills, and relic fuel production such as natural gas processing and coal mining. Nitrous oxide comes from fossil fuel burning and agriculture. Fluorinated gases include hydro-chlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs). These gases are used in refrigeration and aerosol cans (Steinberg, 1998). All of these human practices add greenhouse gases to the Earth’s atmosphere. As the level of greenhouse gases rises, so does the Earth’s temperature. The rise in Earth’s

The Role of the United Nations in Defending International Human Rights Essay

The Role of the United Nations in Defending International Human Rights - Essay Example The United Nations is an organization which was founded in the year 1945, at the signing of the United Nations Charter by 50 countries, and it replaced the League of Nations, which was founded in 1919. Since 1948 there have been 60 UN peacekeeping missions, and thus far, close to 130 nations have contributed personnel at various times. As of the year 2007, there are now 192 United Nations member states, thus encompassing almost every recognized independent state. â€Å"From its headquarters in New York City, the UN and its specialized agencies decide on substantive and administrative issues in regular meetings throughout the year. The organization is divided into administrative bodies, including the General Assembly, Security Council, Economic and Social Council, Secretariat, Trusteeship Council, and the International Court of Justice (ICJ). Additional bodies deal with the governance of all other UN System agencies, such as the World Health Organization (WHO) and United Nationâ€⠄¢s Children Fund (UNICEF). The UN’s most visible public figure is the Secretary-General† (Wikipedia, 2007). The purpose of the United Nations from the very beginning was to maintain international security and peace, seek to develop friendly relations amongst all nations, try to tackle economic and social problems as well as humanitarian issues, and act as a hub for all nations to be able to act together so that as a result their actions could then be directed towards achieving good for the whole of the world....

One of the most major goals of the UN is to defend international human rights, and they are by far the most representative and influential organization in the world in this regards. They have worked dutifully and consistently in order to provide the most stable and secure international human rights and they are constantly striving to even further improve in these areas. The importance of this particular role of the UN has always been evident and present, however more so than ever it has been in recent years, particularly in regards to the complexities and troubles that have been taking place internationally. One of the most recent and significant troubles is that of the invasion of Iraq by the United States, which occurred on March 20, 2003, and which resulted in the winning of a quick military victory and the ousting of the government of Saddam Hussein. Although both the United States and the
