Although animals have evolved over geologic time to Earth's constantly changing environments and the extinctions of certain species are normal, in no other time in the planet's history has the extinction rate climbed as high as it is today. Causes of this include destruction of wildlife habitat, pollution, overfishing, and poaching. Animals illustrates these urgent issues.

While there are several factors that contribute to global warming, such as natural changes in the Earth's inclination and revolution around the sun, by far the biggest factor is the emission of greenhouse gases. This book explores the very important role these gases play and their global impact on populations and ecosystems worldwide.

Global warming has increased dramatically during the last century at an unnatural rate, which makes specialists believe that humans contribute to the real cause of global warming today. Many activities humans are involved in--from burning fossil fuels for energy to massive deforestation--are contributing to the atmospheric warming at an alarming rate. Experts believe that in the future human induced damage will cause severe problems in the distribution of species and their critical habitats, increase the occurrence of severe weather and droughts, contribute to rising sea levels, and...

Earth has always exhibited patterns of heating up and cooling down. This title focuses on the mechanisms that caused past climate changes, putting the Earth repeatedly into and out of ice ages. It compares natural cycles with today's rapid global warming, caused principally by the behavior of humans.
