Electronic wastes also contain many poisonous metals. Even when the machine… and the harmful metals removed, the recycled process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances to escape into the environment.

Creating products out of raw materials creates much more waste material, up to 100 times more, than the material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging it came in. Many wastes produced in the producing process are harmful as well.

The U.S. Environment Protection Agency notes that most waste is dangerous in that “the production, distribution, and use of products--- as well as management of the resulting waste---all result in greenhouse release. Individuals can make contributions by creating less waste at… buying reusable products and recycling.

In many countries, the concept of extended producer responsibility is being considered or has been put in place as an incentive(动机) for reducing waste. If producers are required to take back packaging they use to sell their products, would they reduce the packaging in the first place?

Governments’ incentive to require producers to take responsibility for the packaging they process should be based on money. Why, they ask, should cities or towns be responsible to deal with the bubble wrap(气泡垫) that encased your television?

From the governments’ point of view, a primary goal of laws requiring extended producer responsibility is to transfer both the cost and the physical responsibility of waste management from the government and tax-payers back to the producers.

Suppose you become a leader in an organization. It’s very likely that you’ll want to have volunteers to help with the organization’s activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interests in the work.

Let’s begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get started. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences and to develop social relationships. If volunteer positions do not meet those needs, people may not wish to participate. To select volunteers, you may need to understand the motivation of the people you wish to attract.

People also volunteer because they are required to do so. To increase levels of opportunity given, some schools have launched volunteer programmes. Unlike…. can …people’s wish of participation from an internal factor (e.g. “I volunteer because it’s important to me.”) to an external factor (e.g. “I volunteer because I’m prepared to do so.”) When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activity a must.

Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed volunteers in Florida over a year. One of the most important factors that influenced their satisfactions as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not support you, it leads to important practical advice. The researchers note that attention should be given to “training methods that would prepare volunteers… them with strategies for … with the problem they experience.”

Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view “volunteer” as an important social role. It was estimated that those people …the role of volunteer … part of their personal …be more likely to continue volunteer work. Participants indicated the degree to which social role matters by responding to statements such as “Volunteering at hospitals is an important part of who I am.” Consistent with the researchers’ expectations, they focused a positive cohesion(正相关) between the strength of role identity and the lengths of time people contributed to volunteer. These… again, lead to concrete advice. “Once an individual begins volunteering, continued effort to focus on developing volunteer role….”
