The ocean is one of Earth’s largest and most important natural resources. It regulates rainfall and drought, holds 97% of the planet’s water and absorbs carbon dioxide from the atmosphere. It is home to a huge diversity of life and is essential for human health, including food, jobs and recreation. The sea provides a vital...

Wildlife is a term that includes a wide variety of animals, plants and fungi. They can be found in almost all ecosystems, including deserts, woodlands, wetlands, grasslands, and other areas that are usually considered to be wild. A large number of species of animals are threatened with extinction due to habitat loss, climate change and...

Until the early 20th century, natural factors caused atmospheric carbon dioxide concentrations to vary within a range of about 180 to 300 parts per million by volume (ppmv). Since that time, human activities have increased carbon dioxide emission and have risen the Earth’s CO2 concentration to an unprecedented level. Greenhouse gases cause climate change by...

Wildlife is the group of animals that live in the natural environment. These creatures are important because they help maintain the ecological balance of the world. In addition, they provide us with food, shelter, and entertainment. However, human interference with the wildlife has caused a large decline in their population. This is due to the...

The climate system is a complex natural system that is made up of Earth’s atmosphere, oceans, land surfaces and ice sheets. This system is influenced by many factors, including the balance of energy from the Sun. When a change in the Sun’s output of solar energy affects this balance, Earth’s climate will change. These changes...

The Ocean is a massive system that controls rainfall, droughts, and the Earth’s climate. It holds 97% of the world’s water and helps to keep the carbon cycle balanced by absorbing a third of the planet’s CO2 emissions. It’s also home to more than 226,000 species of living things, from microscopic plankton to huge cetaceans...

Wildlife is an important part of our world’s ecosystems and contributes to the health of our environment. Without wildlife, plants and other organisms would not grow, pollinate, or disperse seeds. Humans have a vital role to play in protecting the natural world and its inhabitants, and conservation is an essential part of that process. The...

Climate Change is caused by human activities, such as burning fossil fuels (coal, oil and natural gas) in the production of electricity and transport. This has changed Earth’s atmosphere and traps heat in the atmosphere, making the planet warmer than it used to be. Solar energy from the Sun enters our planet’s atmosphere and is...

The ocean is the largest body of water on Earth. It covers nearly 70 percent of the surface, and it contains 97% of the world’s water. The ocean is a global system that transports both heat and matter around the planet. It is made up of five main areas: the Pacific, Atlantic, Indian, Arctic and...

Wildlife includes all living creatures, including birds and mammals, that are adapted to a particular habitat without being domesticated. The term was first used to refer to undomesticated animals, but has now expanded to encompass all organisms that exist in the wild in an area free of human intervention. Deserts, woods, rainforests, plains, and other...
