Habitat Loss In the Launch Lab at the beginning of this chapter, you probably observed that lawns and sidewalks have a lower biodiversity than sunlit woods or weed-covered lots. When people alter an ecosystem, perhaps by replacing a forest or meadow with pavement or a lawn, the habitats of some species may become smaller or disappear completely. If the habitats of many species are lost, biodiversity might be reduced. Habitat loss is a major reason why species become threatened or endangered, as...

Visit booke.msscience.com for Web links to information about recycling bottles and cans. Activity Write one argument in support of a money deposit for bottles and cans and one argument against it. Provide data to support one of your arguments. Metals The manufacturing industry has been recycling all kinds of metals, especially steel, for decades. At least 25 percent of the steel in cans, appliances, and automobiles is recycled steel. Up to 100 percent of the steel in plates and beams used to...

Figure 6 Recycling and using nonpolluting types of energy, such as solar energy, are two of the ways Americans are becoming more environmentally conscious. When Europeans began to settle throughout America, it seemed that their way of life would completely replace Native American conservation practices. Many farming techniques used by the new settlers...

Nonrenewable Resources 45.8 billion (45,800,000,000) cans were thrown away in 2000. If it takes 33.79 cans to equal one pound and the average scrap value is 0.58 lb, then what was the total dollar value of the discarded cans 33.

People That Studied Ozone Depletion

Large areas of Brazil's rain forests are being burned to make way for homes, farms, and ranches. Tropical rain forests are located on both sides of the equator. The average temperature in a rain forest is about 25 C and doesn't vary much between day and night. Rain forests receive, on average, between 200 cm and 400 cm of rain each year. Tropical rain forests contain the highest diversity of life on Earth. Scientists estimate that there are about 30 million plant and animal species on this...

Prey And Predator

Prey Running Away From Predator

One habitat might contain hundreds or even thousands of species. Look at the rotting log habitat shown in Figure 16. A rotting log in a forest can be home to many species of insects, including termites that eat decaying wood and ants that feed on the termites. Other species that live on or under the rotting log include millipedes, centipedes, spiders, and worms. You might think that competition for resources would make it impossible for so many species to live in the same habitat. However, each...

Conservation Biology at Work

Florida Panther Territory Map

Almost every conservation plan has two goals. The first goal is to protect a species from harm. The second goal is to protect the species' habitat. Several conservation strategies can be used to meet these goals. Legal Protections Laws can be passed to help protect a species and its habitat. In the early 1970s, people became concerned about the growing number of species extinctions occurring in the United States. In response to this concern, Congress passed the U.S. Endangered Species Act of...

When you wash your hands or flush the toilet, do you think about where the wastewater goes In most places, it eventually ends up being processed in a traditional sewage-treatment facility. But some places are experimenting with a new method that processes wastewater by creating wetlands. Wetlands are home to filtering plants, such as cattails, and sewage-eating...
