The Ocean is the world’s largest body of salt water, covering 70% of Earth and containing 97% of Earth’s water. It has significant impacts on weather, temperature and our food supply. The ancient Greeks conceived of the sea as a vast river encircling the world and were led by their god of the sea, Oceanus...

Climate change refers to long-term changes in Earth’s local, regional and global weather patterns. It is caused by increasing human emissions of heat-trapping greenhouse gases, and it has many significant impacts on ecosystems and living things. These impacts include shrinking glaciers and ice sheets, sea level rise, shifts in precipitation patterns, and increased frequency of...

The world’s wild plants and animals contribute to our health and well-being by providing us with food, materials, recreation and inspiration. But the global wildlife crisis threatens these benefits. Whether it’s the songbird in your backyard or whales in the open sea, many people have some kind of relationship with wildlife. It’s common for humans...

Climate Change refers to the long-term average changes in Earth’s temperature, atmospheric composition and weather patterns. This change has been caused primarily by human activities that increase the levels of heat-trapping greenhouse gases in the atmosphere. These gases warm the planet by trapping some of the sun’s heat and stopping it from escaping into space....

Ocean – 97 percent of Earth’s water is located in the ocean, which plays an important role in weather and climate, as well as providing food and shelter for many animals. The ocean is also a vital resource for human activities, including transportation and recreation. While we know a great deal about the ocean, most...

Wildlife is the animals, plants, and other organisms that exist in their natural environment free of human intervention. Wild species form a rich diversity of life that provides essential functions in ecosystems such as forests, deserts, woods, wetlands, grasslands, and oceans. Billions of people in developed and developing nations depend daily on wildlife for food,...

Climate Change refers to a number of changes in Earth’s atmosphere and surface that are caused by human activities. It includes the warming of the atmosphere and oceans, melting of snow and ice and the changing of weather patterns. These changes have major impacts on people, wildlife and the natural environment. The climate changes we...

Ocean is the world’s largest source of water—covering over 97 percent of Earth’s surface. It plays a critical role in regulating Earth’s climate, temperature, food supply, and more. It is also home to an incredible diversity of life, from microscopic algae and tiny sea stars to the massive blue whale. There are many different types...
