Does organic farming contribute to less pollution?

Yes. Organic farmers also try to do more tasks using human power rather than gas-powered vehicles, thereby using less fuel and cutting down on pollution. Organic farms that raise livestock like dairy cows or chickens feed the animals with natural food, avoiding pollution-causing chemicals and growth hormones that make cows produce more milk and chickens produce more eggs.

Some organic farmers also allow their animals to roam in a large area (such animals are described as “free range”) rather than keeping them in small, climate-controlled pens for their entire lives.

What is the difference between B.C. and A.D.?

The term B.C. stands for “Before Christ,” and is used to date events before the birth of Jesus Christ. A.D. is the abbreviation for the Latin phrase anno domini, which means “in the year of our Lord,” and is used to date events after Jesus’s birth. This system of dating has been used for many years by Western archaeologists. Today, however, with a growing understanding that not all archaeologists are Christians, some archaeologists prefer to use the terms B.C.E. (meaning Before the Common Era) and C.E. (meaning Common Era). These terms are exactly the same as B.C. and A.D., but are not related to Christianity.

How old is the solar system?

Scientists believe that the solar system in about 4.6 billion years old. Earth and the rest of the solar system formed from a giant cloud of gas and dust. Gravity and rotational forces caused the cloud to flatten into a disc and much of the cloud’s mass to drift into the center. This material became the Sun. The leftover parts of the cloud formed small bodies called planetesimals.

These planetesimals collided with each other, gradually forming larger and larger bodies, some of which became the planets. This process took approximately 25 million years, according to scientific estimates.

Why are there wars?

Wars have taken place since the beginning of recorded history, and they surely occurred before that as well. A war begins when one group of people (the aggressors) tries to force its will on another group of people, and those people fight back. War frequently springs from the differences between people, or from the desire of one group to increase its power or wealth by taking control of another group’s land. Often the aggressors feel that they are superior to the group they want to dominate: they believe that their religion, culture, or even race is better than that of the people they wish to defeat. This sense of superiority makes them feel that it is acceptable to fight to take the land, possessions, and even lives of the “inferior” group, or to force their ways on the dominated people.

Because countries can be very different from one another in government, religion, customs, and ideology (ways of thinking), it is not surprising that nations disagree on many things. But great efforts are usually made to settle the disagreements through discussion and negotiation—a process called diplomacy—before they result in anything as destructive as a war. War usually occurs when diplomacy fails. Because science and technology have allowed us to create such powerful and destructive weapons that can result in such devastating wars, we now have international organizations that work all the time to try to keep peace among nations.

What is Earth Day?

Earth Day is a national holiday that was first celebrated on April 22, 1970. It was created by Senator Gaylord Nelson, a Democrat from Wisconsin who was elected to the U.S. Senate in 1962. Senator Nelson decided to set aside one day aside for the entire nation to focus on environmental issues, learn about ways to improve the environment, and protest against the federal government’s unwillingness to help solve problems such as air pollution and the widespread destruction of forests.

After lots of hard work and publicity, on the first Earth Day 20 million Americans gathered at different places from the East to West coasts to hear speeches, participate in community-wide cleanup efforts, and demonstrate to the government that the environment is a major national issue. Ever since then, April 22 has been the date for celebrating Earth Day—a time when the United States (and now many countries all over the world) could participate in educational activities that celebrate Earth and think of new ways to preserve our natural resources. On Earth Day 2008, over 100 million people joined in the effort to celebrate and protect our planet.

Why is it important to vote?

Republics such as the United States are based upon a voting population. If the citizens of the country do not vote, then politicians do not necessarily need to heed their interests.

It is necessary for the people of a democratic country to constitutionally voice their opinions, and they do this by voting for state propositions and for their city, state, and country’s leaders.

How did we get the idea that the stork delivered babies?

The suggestion that storks delivered babies came from Scandinavia and was promoted by the writings of Hans Christian Andersen. Storks had a habit of nesting on warm chimneys and would often lift articles from clotheslines then stuff them into these nests, which to children looked like they were stuffing babies down the flue.

The stork is also very nurturing and protective of its young, which helped it become symbolic of good parenthood.

What is the difference between a “flock” and a “gaggle” of geese?

Any group of birds, goats, or sheep can be referred to as a flock, but each feathered breed has its own proper title. Hawks travel in casts, while it’s a bevy of quail, a host of sparrows, and a covey of partridges.

 

Swans move in herds, and peacocks in musters, while a flock of herons is called a siege. A group of geese is properly called a gaggle, but only When they’re on the ground. In the air they are a skein.

How long is a fortnight?

The word fortnight is a unit of time that equals fourteen days. It comes from the Old English word feorwertyne niht, meaning “fourteen nights.” The term is used in Great Britain, where salaries and most social security benefits are paid on a fortnightly basis, but in the United States people use the term “two weeks.”

In many languages, there is no single word for a two-week period and the equivalent of “fourteen days” has to be used. In Spanish, Italian, French, and Portuguese, the terms quince días, quindicina, quinzaine, and quinzena—all meaning “fifteen days”—are used.

What does the slogan “Reduce, Reuse, and Recycle” mean?

You may have heard this expression used in school, in television commercials, or on a sign at your local parks and recreation. Basically, the slogan means that there are three key ways to produce less waste:
1. Reduce the amount of trash (and toxicity) you throw away.
2. Reuse containers and products whenever possible.

3. Recycle as much as possible and buy products with recycled content. As much as 84 percent of all household waste can be recycled—so it makes sense to be conscious of what we use and how we can reuse it.
