Environment

The environment is something you are very familiar with. It's everything that makes up our surroundings and affects our ability to live on the earth—the air we breathe, the water that covers most of the earth's surface, the plants and animals around us, and much more.

In recent years, scientists have been carefully examining the ways that people affect the environment. They have found that we are causing air pollution, deforestation, acid rain, and other problems that are dangerous both to the earth and to ourselves. These days, when you hear people talk about “the environment”, they are often referring to the overall condition of our planet, or how healthy it is

                                                                              Travel 

Travel is the movement of people between relatively distant geographical locations, and can involve travel by foot,bicycle,automobile,train,boat,airplane, or other means, with or without luggage, and can be one way or round trip. Travel can also include relatively short stays between successive movements.The origin of the word "travel" is most likely lost to history. The term "travel" may originate from the Old French word travail. According to the Merriam Webster dictionary, the first known use of the word travel was in the 14th century. It also states that the word comes from Middle English travailen,travelen (which means to torment, labor, strive, journey) and earlier from Old French traveler (which means to work strenuously, toil). In English we still occasionally use the words travail and travails, which mean struggle. According to Simon Winchester in his book The Best Travelers' Tales (2004), the words travel and travail both share an even more ancient root: a Roman instrument of torture called the trillium (in Latin it means "three stakes", as in to impale). This link reflects the extreme difficulty of travel in ancient times. Also note the torturous connotation of the word "traveler." Today, travel may or may not be much easier depending upon the destination you choose (i.e.,Mt.Everest, the Amazon rainforest), how you plan to get there ( tour bus,cruise ship, or oxcart), and whether or not you decide to "rough it (see extreme tourism and adventure travel). "There's a big difference between simply being a tourist and being a true world traveler," notes travel writer Michael Kasum. This is, however, a contested distinction as academic work on the cultures and sociology of travel has noted.       

Reasons for traveling include recreation, tourism or vacationing, research travel for the gathering of information, for holiday to visit people,volunteer travel  for charity,migration to begin life somewhere else, religious pilgrimages  and mission trips,business travel, trade, commuting, and other reasons, such as to obtain health care or fleeing war or for the enjoyment of traveling. Travel may occur by human-powered transport such as walking orbicycling,or with vehicles, such as public transport,automobiles, trains and airplanes.Motives to travel include pleasure,  relaxation,discovery and exploration, getting to know other cultures and taking personal time for building interpersonal relationships. Travel may be local, regional, national (domestic) or international. In some countries, non-local internal travel may require an internal passport , while international travel typically requires a passport and visa. A trip may also be part of a round-trip, which is a particular type of travel whereby a person moves from one location to another and returns.

Authorities emphasize the importance of taking precautions to ensure travel safety. When traveling abroad, the odds favor a safe and incident-free trip, however, travelers can be subject to difficulties, crime and violence. Some safety considerations include being aware of one's surroundings,avoiding being the target of a crime, leaving copies of one's passport and itinerary information with trusted people, obtaining medical insurance valid in the country being visited and registering with one's national embassy when arriving in a foreign country. Many countries do not recognize drivers' licenses from other countries; however most countries accept international driving permits.Automobile insurance policies issued in one's own country are often invalid in foreign countries, and it's often a requirement to obtain temporary auto insurance valid in the country being visited. It is also advisable to become oriented with the driving-rules and -regulations of destination countries. Wearing a seat belt is highly advisable for safety reasons; many countries have penalties for violating seat belt laws.
