An ocean is a large body of salt water that covers more than two-thirds of Earth’s surface. It plays a critical role in providing food, oxygen and shelter for many forms of marine life, including microscopic plankton and fish, marine mammals, coral reefs, and other plants. Oceans also provide a vital source of transportation and...

The term wildlife refers to all the undomesticated life forms of the planet including animals, birds, plants, fungi and even microscopic organisms that live in their natural habitat without human interference. This wild ecosystem is essential to maintain a healthy ecological balance on the earth, and also provides boons like food, recreational opportunities and scientific...

Throughout Earth history, climate has constantly changed. But current climate change is occurring much faster and on a much grander scale than at any time in our planet’s history. Scientists agree that this rapid and widespread warming is mainly due to human activities, particularly burning fossil fuels like oil, natural gas and coal. These fuels...

The ocean is Earth’s largest network of salt water covering more than three-quarters of the planet. Its name is derived from the Greek god Oceanus, who was personified as an enormous river circling the world. When we speak of the ocean, we usually mean one of the four major areas of global seas: the Pacific,...

Wildlife is the natural living organisms in the ecosystems that maintain ecological balance. These include animals, plants, fungi and microorganisms. Wildlife can be found everywhere on Earth including deserts, forests, mountain ranges and other habitats. Wildlife is also found in the water bodies, including rivers, lakes and seas. The term ‘wildlife’ is generally used to...

Climate Change refers to changes in Earth’s average temperature and other weather patterns that are caused by human activities. The changes are causing many effects, including melting ice sheets and sea levels rising, droughts and heat waves, and changing ecosystems. The changes are expected to become more severe over time. Most scientists agree that climate...

Ocean is a large body of salty water that covers 71% of Earth’s surface. It is the largest living ecosystem, home to countless species including fish, plants, and marine mammals. Its vast expanse and complex chemistry make it a fascinating system. Scientists study its natural processes to understand how it works, and its role in...

Wildlife refers to all living creatures that grow or live in a wild environment free from human interference. This includes plants as well as animals. It is a major part of the natural world that provides boons to people like food, medicinal value, scientific research opportunities and esthetics. Earlier, the number of wildlife was quite...

Climate Change is a complex and interconnected set of global environmental phenomena. It involves temperature rise, changes in sea level and weather patterns like droughts and floods. These phenomena affect all areas of the planet and are having profound impacts on people, wildlife and the things we value—like food, water, jobs, and natural habitats. Human...

Ocean is a huge body of saltwater that covers about 71% of the Earth’s surface. It supplies more than half of the world’s oxygen and stores 50 times more carbon than the atmosphere. It also influences the climate of our planet by absorbing heat and carbon dioxide, regulating weather patterns and preventing abrupt temperature fluctuations....
