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.

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.
