In English, proper nouns are not normally preceded by an article or other limiting modifier (such as "any" or "some"), and are used to denote a particular person, place, or object without regard to any descriptive meaning the word or phrase may have (for example, a town called "Newtown" may be, but does not necessarily have to be, a new [recently built] town).
Which nouns are considered proper names depends on language. For example, names of days and months are considered proper names in English, but not in Spanish, French, Swedish, Slovenian or Finnish, where they are not capitalized.
Plastic
A plastic is a material that can change its shape easily. Many things are made of plastics, usually because making them to the right shape is easy. There are many types of plastic. Some can be shaped only when they are freshly made; then they become hard. Others are thermoplastic and can be softened by heating them. These plastics can be used for 3D printing, because the plastic will become soft enough to form into different shapes, and then become hard again when they cool down.
Most plastics are man-made; they do not occur in nature. The process of making plastics is usually quite complicated. Most of the materials that are called "plastic" are polymers. Polymers are long chains of atoms bonded to each other. In most plastics, the long chain is a chain of carbon atoms with other atoms attached to them. The different atoms and the shape and length of the chains change how the plastic looks and works.
People experimented with plastics based on natural polymers for a very long time. Alexander Parkes, an English inventor (1813-1890), created an early form of plastic in 1855. It was hard but flexible and transparent. He called it "Parkesine" but now it is called "Celluloid."
Old plastics are usually thrown away and put in landfills. Some plastics release toxic fumes when heated. Some plastics are recycled so they won't become waste. Some plastics have other materials added to them, like glass, because they make the plastic stronger and stiffer.
Plastics are mostly petrochemicals, made from natural gas or from petroleum, a type of oil. Chemical engineers refine the petroleum which goes through a heating process. It develops ethylene and propylene, which are the chemical building blocks for many plastics. These chemicals are then combined with other chemicals to produce a polymer.
Today, some of these plastics are also being made without oil. Instead, other sources like plants and bacteria are used to make the plastic. These plastics are called bioplastics. They are useful because they can be eaten by other bacteria instead of throwing them away.
Product stewardship
Product stewardship includes waste disposal measures in the distribution of an industrial product. That is, paying for the safe and proper disposal when you pay for the product, and relying on those who sold it to you, to dispose of it.
The slightly more specific idea of product take-back means that the service of waste disposal is paid for at time of purchase. It is often applied to paint, tires, and other goods that become toxic waste if not disposed of properly. It is most familiar as the deposit bottle - where one pays for the loan of the bottle at the same time as one purchases what is inside it. The container deposit charged for a deposit bottle may be a fee to "buy" the bottle, separately from the fee to buy what it contains. If one returns the bottle, the fee is returned, and the supplier must return the bottle for re-use or recycling. If not, one has paid the fee, and presumably this can pay for landfill or litter control measures that dispose of say a broken bottle. Also, since the same fee can be collected by anyone finding and returning the bottle, it is common for people to collect these and return them as a means of surviving. This is quite common for instance among homeless people.
Legal requirements vary: the bottle itself may be considered simple property of the purchaser of the contents, or, the purchaser may have some obligation to return the bottle to some depot so it can be recycled or re-used. For the more toxic items, it is more likely that returning it is required:
This principle is applied very broadly beyond bottles to paint and automobile parts such as tires. When purchasing paint or tires in many places, one simultaneously pays for the disposal of the toxic waste they become. In some countries, such as Germany, law requires attention to the comprehensive outcome of the whole extraction, production, distribution, use and waste of a product, and holds those profiting from these legally responsible for any outcome along the way. This is also the trend in the UK and EU generally. In the United States, there have been many class action suits that are effectively product stewardship liability - holding companies responsible for things the product does, which it was never advertised to do.
Rather than let liability for these problems be taken up by the public sector or be haphazardly assigned one issue at a time to companies via lawsuits, many accounting reform efforts focus on achieving full cost accounting. This is the financial reflection of the comprehensive outcome - noting the gains and losses to all parties involved, not just those investing or purchasing. Such moves have made moral purchasing more attractive, as it avoids liability and future lawsuits.
So these are partial implementations of a strict service economy ideal.
Those who advocate these measures are concerned with the later phases of product lifecycle and the comprehensive outcome of the whole production process. It is considered a pre-requisite to a strict service economy interpretation of (fictional, national, legal) "commodity" and "product" relationships.
Peace
Peace is a time without any fights or wars. In a larger sense, peace (or peacefulness) can mean a state of harmony, quiet or calm that is not disturbed by anything at all, like a still pond with no ripples.
Many people and organizations want peace. One organization that was set up to bring peace among the nations and try to make war a thing of the past was the League of Nations after World War I. When it did not stop World War II, it was replaced by the United Nations which tries to make the world peaceful. This means that if any member is attacked or invaded by another country without attacking that country first, the other members will come to help the country that was attacked first. This idea was used by the United Nations to defend both South Korea and Kuwait when they were attacked.
Martin Luther King, Jr. wrote in a letter he sent from the Birmingham jail that, "True peace is not merely the absence of tension: it is the presence of justice." In other words, Real peace is more than just problems being gone: there must be fairness to have peace.
Alfred Nobel created an annual award, the Nobel Peace Prize, for the person who had done the most to bring peace to the world.
Buddhists think that peace can be gotten once all suffering ends.To get rid of suffering and get this peace, many try to follow a set of teachings called the Four Noble Truths
Jews and Christians believe that true peace comes from a personal relationship with God. Jesus Christ (also called the "Prince of Peace" in the Book of Isaiah) said: "Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid." ()
Inner peace (or peace of mind) refers to a state of being mentally and spiritually at peace, with enough knowledge and understanding to keep oneself strong in the face of stress. Being "at peace" is considered by many to be healthy and the opposite of being stressed or anxious. Peace of mind is generally associated with bliss and happiness.
