So far, two nuclear weapons have been used during warfare. They were used in the atomic bombings of Hiroshima and Nagasaki and resulted in the deaths of approximately 120,000 people. Thousands of much more powerful bombs were made in later years. They have not yet been used in war.
Nuclear bombs were invented by the United States with Canadian and British help during World War II to help make that war stop. The destruction of Hiroshima and Nagasaki and the Soviet invasion of Manchuria caused Japan to surrender. They are still the only nuclear weapons that have ever been used in fighting a war. At that time only the United States had the technology needed to make the bomb, but within a few years the Soviet Union had developed it too. In the new Cold War, the United States and the Soviet Union were enemies and each had many nuclear weapons, but they did not dare to use them against each other, either directly or by attacking the other country's allies. Since either country could be completely destroyed by the other's weapons, nuclear war could no longer be limited to the use of only one or two bombs; if they were used anywhere by one side, the other would attack with its own nuclear weapons, and the fighting would almost certainly become greater. This situation came to be known as the "balance of terror," or Mutually Assured Destruction, and stopped conflicts between the two superpowers from leading to a third world war.
Since the end of Communist rule in Russia and Eastern Europe, tensions between America and Russia have eased and war has become less likely. However, today there is more worry about nuclear proliferation. Countries around the world who already have their own bombs include Britain, France, China, Israel, India, Pakistan and North Korea; as all kinds of technology tend to become cheaper and easier to get and use, there is a fear that nuclear weapons could become available to countries with unstable governments. There is also the possibility that terrorists might be able to capture or build nuclear weapons and use them.
Ever since the end of World War II, writers, film-makers, and artists have created works of fiction imagining how a nuclear war might happen and what life would be like afterwards. Most have pictured widespread death and destruction, and a grim post-armageddon world where a few survivors struggle to live without power, medicine, or food. Some have pictured civilization breaking down completely, and primitive societies developing; with the past world becoming forgotten.
Tax
Tax is money that people have to pay to the government.
The government uses the money it gets from taxes to pay for things. For example, taxes are used to pay for people who work for the government, such as the military and police, provide services such as education and health care, and to maintain or build things like roads, bridges and sewers.
There are many different kinds of taxes. They may be direct tax or indirect tax.
Taxes can also be split into 3 groups:
Often because different parts of governments use taxes for different things, people end up paying lots of taxes.
In the United States, for example, the national government has an income tax; most states have an income tax or a sales tax, or both; and cities and towns may have a sales tax or a property tax. In some states such as Ohio, the sales tax is different in each county.
In ancient times, people from one city or area would attack another place, and make the people there pay "tribute". Tribute meant that the attacked people would pay money (or other things), and the attacker would stop attacking them. A famous tribute was the Danegeld, when people from Denmark conquered part of England and made the English pay thousands of silver coins.
Anarchists and Libertarians are against all taxes or against high taxes. As people are paying them unwillingly and under the threat of sanctions, they say that taxation is the same as robbery.
Florida
Florida (), officially the State of Florida, is a state in the southeast part of the United States. It is the 22nd largest US state by total area with 65,757.70 sq mi (170,312 km) and the third most-populous with a 2015 population of more than 21 million. It is a peninsula, which means that water surrounds the state on three of four possible sides. To the west is the Gulf of Mexico, to the south is the Florida Straits, and to the east is the Atlantic Ocean. The highest elevation in Florida is Britton Hill. Many Cubans, Haitians and other Caribbeans live in state.
Native Americans first settled in Florida before the arrival of the Europeans. Florida had many residents from many tribes and nations living in almost all parts of it for thousands of years. These include the Timucua, the Tequesta, the Calusa, the Seminole, the Miccosukee, and many more. Florida was first discovered by a European in 1513 by the Spanish Ponce De Leon, who called this peninsula "Tierra de la Pascua Florida" (Land of the Easter flowered) because it was discovered on Easter: in the next centuries only the last word remained.
Northern Florida contains hills because it is at the very end of the Appalachian Mountains. The highest hill in Florida is Britton Hill, in northern Walton County near the town of Lakewood, Florida. It is above sea level. It is the shortest of the highest points in all other states.
Florida has the longest coastline in the continental United States.The Gulf Stream ocean current goes through the Atlantic Ocean near the east coast of Florida, so the water is warmer than the Pacific Ocean. The Gulf of Mexico is on the west coast of Florida.
In the center of southern Florida is a lake called Lake Okeechobee. It is the seventh largest freshwater lake in the United States and the second largest freshwater lake entirely within the lower 48 states. Okeechobee is 730 square miles (1,890 km²), about half the size of the state of Rhode Island, and is very shallow for a lake of its size, with an average depth of only 9 feet (3 m).
A lot of south Florida used to be covered by a swamp called the Everglades. When Florida was first being settled, farmers found out the soil there was fertile, so they drained some of the wetlands in 1882 for farming. In 1947, the state constructed levees and canals to make more room for farming and houses. The Everglades is now about half the size it used to be. Most of what is left is now the Everglades National Park. Lots of animals live there, including alligators and Florida panthers. Recently, Florida has been trying to restore the Everglades.
At the southernmost tip of Florida is a chain of islands called the Florida Keys. There are 4500 islands in the Keys. The most famous one is Key West.
Florida is nicknamed the Sunshine State. During the summer, temperatures may rise up to as high as 109 degrees Fahrenheit (or 40.5 degrees Celsius). Its annual average temperature is much warmer than many of the other states, but during winter, temperatures occasionally fall below 32 degrees Fahrenheit. In Florida, a dozen palm tree species are native to the state. Florida has both a rainy season and dry season. Southern Florida does not have four separate seasons.
Florida's sunny climate attracts visitors. The summer is great for surfing the waves and enjoying the beaches. The most popular sport in Florida is fishing.
Florida is vulnerable to hurricanes due to its proximity to the warm waters of the Atlantic Ocean and Gulf of Mexico. Hurricane season is from June 1 to November 30, but sometimes a hurricane will occur outside of this period. Hurricane Andrew was a destructive hurricane that hit Florida on August 23, 1992. Florida's most active recorded hurricane seasons were in 2004 and 2005, when it was hit by hurricanes Charley (August 13), Frances (September 4–5), Ivan (September 16), Jeanne (September 25), Katrina (August 25), and Wilma (October 24).
Florida has many types of wildlife including:
