Context: From a human point of view, natural resources can be classified as either renewable or nonrenewable. Renewable resources are natural resources that are remade by natural processes as quickly as people use them. Examples of renewable resources include sunlight and wind. They are in no danger of being used up. Metals and some other minerals are considered renewable as well because they are not destroyed when they are used. Instead, they can be recycled and used over and over again. Living things are also renewable resources. They can reproduce to replace themselves. However, living things can be over-used or misused to the point of extinction. For example, over-fishing has caused some of the best fishing spots in the ocean to be nearly depleted, threatening entire fish species with extinction. To be truly renewable, living things must be used wisely. They must be used in a way that meets the needs of the present generation but also preserves them for future generations. Using resources in this way is called sustainable use. Nonrenewable resources are natural resources that cant be remade or else take too long to remake to keep up with human use. Examples of nonrenewable resources are coal, oil, and natural gas, all of which are fossil fuels. Fossil fuels form from the remains of plants and animals over hundreds of millions of years. We are using them up far faster than they can be replaced. At current rates of use, oil and natural gas will be used up in just a few decades, and coal will be used up in a couple of centuries. Uranium is another nonrenewable resource. It is used to produce nuclear power. Uranium is a naturally occurring chemical element that cant be remade. It will run out sooner or later if nuclear energy continues to be used. Soil is a very important natural resource. Plants need soil to grow, and plants are the basis of terrestrial ecosystems. Theoretically, soil can be remade. However, it takes millions of years for soil to form, so from a human point of view, it is a nonrenewable resource. Soil can be misused and eroded (see Figure 25.9). It must be used wisely to preserve it for the future. This means taking steps to avoid soil erosion and contamination of soil by toxins such as oil spills. Some of the resources we depend on the most are energy resources. Whether its powering our lights and computers, heating our homes, or providing energy for cars and other vehicles, its hard to imagine what our lives would be like without a constant supply of energy. Fossil fuels and nuclear energy are nonrenewable energy resources. People worldwide depend far more on these energy sources than any others. Figure 25.10 shows the worldwide consumption of energy sources by type in 2010. Nonrenewable energy sources accounted for 83 percent of the total energy used. Fossil fuels and the uranium needed for nuclear power will soon be used up if we continue to consume them at these rates. Using fossil fuels and nuclear energy creates other problems as well. The burning of fossil fuels releases carbon dioxide into the atmosphere. This is one of the major greenhouse gases causing global climate change. Nuclear power creates another set of problems, including the disposal of radioactive waste. Switching to renewable energy sources solves many of the problems associated with nonrenewable energy. While it may be expensive to develop renewable energy sources, they are clearly the way of the future. Figure 25.11 represents three different renewable energy sources: solar, wind, and biomass energy. The three types are described below.

Solar cells can turn sunlight into electricity. The energy in sunlight is virtually limitless and free and creates no pollution to use. Wind energy is energy provided by the blowing wind. Wind turbines, like those in Figure 25.11, can turn wind energy into electricity. The wind blows because of differences in heating of Earths atmosphere by the sun. There will never be a shortage of wind. Biomass energy is energy provided by burning

answer:
decades.


question:
Context: Ten-year-old Chihiro (voice: Daveigh Chase in the 2002 English dub) and her parents (voices: Lauren Holly and Michael Chiklis) drive to their new home. Chihiro is whiny and unhappy about the move, especially when she notices that the bouquet her friend gave her as a good-bye gift is wilting. In sight of their new house, they take a wrong turn and follow a bumpy, decayed old road through the woods; Chihiro sees an odd old statue through the trees as they drive by. The road ends at a tunnel leading to an abandoned theme park. It gives Chihiro the creeps, but her parents persuade her to go in with them and look around.After wandering across a grassy landscape and a dry riverbed, they climb a stone staircase and come to a street lined with restaurants and shops. Most are deserted, but the aroma of cooking leads them to the one restaurant that's well stocked with food -- though it's mysteriously deserted. Mom and Dad are hungry and start eating, despite Chihiro's objections. The food is delicious, and Chihiro wanders away to explore while they eat. She finds a towering, ornate building that she recognizes as a bathhouse (a spa resort); there's a train track running under it. She meets a boy (voice: Jason Marsden) in traditional dress who is alarmed to see her; he tells her to leave and get back across the river before it gets dark. Chihiro runs back to her parents, but they're still eating -- and they've turned into pigs. Strange, dark, ghostly figures appear in all the shops and streets, frightening Chihiro and separating her from the pigs that were her parents. Chihiro runs back to the river, which was nearly dry when they came over but is now full and large, and she doesn't even recognize the buildings on the far side. As a riverboat approaches, she notices that her body has become transparent.The riverboat lands a big crowd of people in costume -- or maybe they're not people; at first they're only visible as paper masks. Chihiro thinks shes dreaming, but can't wake up. The boy who warned her away finds her and tells her she must eat some food from his world or she'll fade away. He assures her that she won't turn into a pig. She swallows the morsel he gives her and becomes solid, but finds that she's stuck to the ground until he recites an incantation to release her. A bird with a woman's head flies above them and he hides her, saying the bird is looking for her. They run through alleys and the pig barn to the big bathhouse, which is accessed by a bridge; the boy says she has to hold her breath as they cross the bridge or the spell that makes her invisible will be broken. Customers -- fantastically varied gods and spirits -- are crossing the bridge and being greeted by bathhouse staff. Chihiro makes it almost all the way across, but a frog (voice: Bob Bergen) that speaks to her companion (calling him Haku) startles her and she takes a breath. Luckily only the frog seems to see her, and Haku uses magic to encase it in a bubble to shut it up.Haku tells her to find Kamajii (voice: David Ogden Stiers), the boiler man, and make him give her a job; she must have a job to stay at the bathhouse, or else Yubaba (voice: Suzanne Pleshette), the old witch who rules the bathhouse, will turn her into an animal. And Haku says she has to stay if she wants to find and help her parents, who are still pigs, wherever they are. He knows her name and says he's known her since she was very small.Chihiro descends a steep, winding, rail-less wooden stairway in search of Kamajii and the boiler room. When she finds them, she sees a weird set-up in which the boiler is fed by creatures like spiders (delivering coal one lump at a time) and the machinery is controlled by a bearded, bald man
