Climate Change is a change in the average weather conditions over time, including temperature, rainfall, wind, and other factors that affect local, regional, and global patterns. While the Earth’s climate has naturally fluctuated throughout history, the rapid warming we have seen over the past century is unequivocally caused by humans. The current warming is largely...

A massive, salty body of water that covers more than 70 percent of the planet. The ocean is home to a wide variety of organisms—including bacteria, protists, algae, fish, shellfish and mammals. It also provides important natural resources such as oxygen, food and minerals. The ocean moderates Earth’s climate and plays key roles in the...

Wildlife is the wild plants, animals, and other living things that inhabit the Earth. It includes everything from a backyard songbird to whales in the open sea. In addition to their intrinsic value, wildlife serves a number of important ecological and economic functions. Wildlife conservation has a great impact on people and is crucial to...

Over the past few decades, scientists have discovered changes to Earth’s climate, and the evidence points to the fact that humans are the dominant cause of those changes. These changes include increasing temperatures, melting glaciers and ice sheets, rising sea levels, and more severe weather. The climate system is a complex web of interactions among...

The world’s oceans are a vast and fascinating place. They cover more than 70% of the planet’s surface and provide food, shelter, and energy for many species. They also play a key role in the Earth’s climate. The word “ocean” means a large body of salt water that connects smaller seas and covers most of...

Wildlife is the name given to undomesticated animal species and all organisms that grow or live wild in an area without being introduced by humans. It is found in all ecosystems. It traditionally refers to animals whose natural habitat is outside human control or influence, but it has come to include all living things that...

Climate Change refers to the overall warming of Earth’s atmosphere, oceans and land that we’ve observed over the last century due to increased greenhouse gas levels in the air. These gases, mainly carbon dioxide (CO2) and methane, trap heat from the Sun, stopping it from escaping back into space and instead heating the planet. Human...

Oceans provide a vital source of oxygen through photosynthesis performed by marine plants. They are also home to fish, marine mammals and other forms of life. They are major shipping routes and provide raw materials used in technology, transportation and construction. In addition, oceans are important sources of food and recreation. Oceanography is the scientific...

Wildlife is non-domesticated animal species and other organisms that live in wild areas of the world. It includes all living things that are not farm animals or pets, such as birds, insects, reptiles and mammals. Wildlife is important because it plays a role in the balance and stability of Earth’s ecosystems. Wildlife is found in...

Climate Change is caused by human activity that adds heat-trapping pollution to Earth’s atmosphere, causing the planet to warm. The most important human activities that cause this warming are burning fossil fuels – like coal, oil and gas – to produce energy, deforestation and farming. These activities also release heat-trapping gases, called greenhouse gases. The...
