Global Issues: Classroom Set, Spanish

6 copies each of all three reading levels, 18 books total. For plants and animals, every place on Earth is a home, or habitat, which provides food, water, and shelter. Yet scientists are finding that habitats for many animals and plants around the world are shrinking. As a result, their populations are declining. The trend is a challenge of biodiversity, which is the range of living things on Earth. Habitat Preservation explores how countries around the world are using conservation and a smarter use of resources to protect the habitats of living things.

6 copies each of all three reading levels, 18 books total. The world's population has risen to more than 7 billion people, making issues such as food supply, energy resources, and water quality even more serious. Population Growth examines this major issue in ways that emphasize the causes and effects of population growth. In addition, it examines why some countries face the challenge of a young population, while other countries must maintain the quality of life for an aging population. Finally, Population Growth explores the importance of education and economic opportunities in meeting these important challenges.

6 copies each of all three reading levels, 18 books total. Pollution is a growing problem around the globe. Using chemicals, old appliances, exhaust fumes, and plastics are just a few of the things that cause pollution on our planet. Pollution examines how water, soil, and the atmosphere have become increasingly polluted and the impact that pollution has on people's health. In the face of these challenges, people and countries have cooperated to clean up natural environments. They are also working to prevent pollution through technology, better planning, transportation alternatives, and more.

6 copies each of all three reading levels, 18 books total. According to most scientists, Earth's atmosphere has warmed by about 1.4 degrees Fahrenheit in the past 100 years. The result has been melting glaciers, rising sea levels, and more extreme weather events. Some people say that current climate change is part of the natural cycle of changes on Earth. Many scientists, however, think that Earth's climate is changing because of increased greenhouse gases in the atmosphere. Climate Change examines how countries around the world are taking steps, such as conservation, to lessen the effects of climate change.

6 copies each of all three reading levels, 18 books total. At the center of many conflicts around the world are human rights, making this one of the key issues in the world today. These rights include the freedom to vote, to assemble, to speak one's mind, to be treated fairly before the law, and to gain an education. In several societies around the world, people are struggling to gain their rights. However, as Human Rights explains, people have shown great courage as they overcome serious obstacles to gain their rights and exercise democratic freedoms.

The world's population has risen to more than 7 billion people, making issues such as food supply, energy resources, and water quality even more serious. Population Growth examines this major issue in ways that emphasize the causes and effects of population growth. In addition, it examines why some countries face the challenge of a young population, while other countries must maintain the quality of life for an aging population. Finally, Population Growth explores the importance of education and economic opportunities in meeting these important challenges.

Water is an essential resource for life on Earth. Considering how vital and precious water is, it is almost unbelievable that it can be used so carelessly. Sewage, toxic chemicals, fertilizers, pesticides, oil, metals, and solid trash pollute the water in lakes, streams, and oceans around the world. Water Resources explores the ways in which water on Earth has become polluted--and what people around the globe are doing to solve this problem.

Globalization connects governments, cultures, and economies, making it easier for people to make, sell, and buy goods worldwide. It brings different people more easily into contact, but it can also disrupt traditional cultures. It helps create jobs in poor countries and allows businesses to make goods more cheaply. However, it can also widen the gap between rich and poor. Globalization explains how people are working to bring the positive effects of globalization to populations around the world.

Food Supply examines the challenges of feeding a world that is home to more than 7 billion people. Every day, nearly 1 billion people go hungry. The causes of food shortages include crop failure, soil depletion, flood, drought, and poor food distribution. To address these issues, many aid groups are developing strategies to increase crop yields. Food Supply explains how different countries are meeting the challenges by using a variety of measures, from better fertilizers to improved education for farmers.

Energy use is one of the key issues of our time. People have traditionally relied on fossil fuels, including oil, coal, and natural gas. There are growing concerns, though, about the pollution caused by these energy resources. In addition, these sources of energy are nonrenewable. That is, they can be used up. Countries around the world are exploring ways to use renewable sources of energy, such as solar power. Energy Resources examines the role of traditional sources of energy and the development of alternative energy resources.

Standards of living vary from country to country, and from one community to another. In general, a family in a developed country lives more comfortably than a family in a less developed country. People have more to ear, access to education, better health care, and safer homes. Standard of Living examines the factors that affect people's economic well-being, including war, historical factors, and resource management. In addition, it highlights countries that have successfully raised their standard of living, providing hope for the populations of the world.

From the beginning of human history, people have moved from one place to another. They seek better jobs and schools and leave behind unstable political conditions and limited opportunities. These factors often cause people to immigrate from less developed countries to more developed countries. The same factors also lead people to migrate within a country. Migration examines the forces behind migration, the challenges that migrants face, and the ways in which new populations enrich their communities.

Health is not just about a person's diet, fitness, and genes. Life expectancy, or how long people are likely to live, is also a reflection of the society in which people live. A society's culture, politics, economy, and access to health care all have a tremendous impact on people's health. Health examines the positive changes taking place around the world. People are working to bring better access to doctors and nurses to improve everyone's health.

The world's population has risen to more than 7 billion people, making issues such as food supply, energy resources, and water quality even more serious. Population Growth examines this major issue in ways that emphasize the causes and effects of population growth. In addition, it examines why some countries face the challenge of a young population, while other countries must maintain the quality of life for an aging population. Finally, Population Growth explores the importance of education and economic opportunities in meeting these important challenges.
