The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to the Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity.
The concept of the natural environment can be distinguished as components:
In contrast to the natural environment is the built environment. In such areas where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams, and the works of mound-building termites, are thought of as natural.
People seldom find absolutely natural environments on Earth, and naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different.
Natural environment is often used as a synonym for habitat, for instance, when we say that the natural environment of giraffes is the savanna. (Full article...)
While most of the large hydropower plants in Russia date from the Soviet era, the abundance of fossil fuels in the Soviet Union and the Russian Federation has resulted in little need for the development of other renewable energy sources. In the early 21st century Russian Prime Minister Dmitry Medvedev called for renewable energy to have a larger share of Russia's energy output, and took steps to promote the development of renewable energy. But by 2020 wind and solar only amounted to 0.2% of electricity generation, compared to the world average of 10%. (Full article...)
Marjory Stoneman Douglas (April 7, 1890 – May 14, 1998) was an American journalist, author, women's suffrage advocate, and conservationist known for her staunch defense of the Everglades against efforts to drain it and reclaim land for development. Moving to Miami as a young woman to work for The Miami Herald, she became a freelance writer, producing over one hundred short stories that were published in popular magazines. Her most influential work was the book The Everglades: River of Grass (1947), which redefined the popular conception of the Everglades as a treasured river instead of a worthless swamp. Its impact has been compared to that of Rachel Carson's influential book Silent Spring (1962). Her books, stories, and journalism career brought her influence in Miami, enabling her to advance her causes.
As a young woman, Douglas was outspoken and politically conscious of the women's suffrage and civil rights movements. She was called upon to take a central role in the protection of the Everglades when she was 79 years old. For the remaining 29 years of her life she was "a relentless reporter and fearless crusader" for the natural preservation and restoration of South Florida. Her tireless efforts earned her several variations of the nickname "Grande Dame of the Everglades" as well as the hostility of agricultural and business interests looking to benefit from land development in Florida. She received numerous awards, including the Presidential Medal of Freedom, and was inducted into several halls of fame. (Full article...)

Loch Lomond in Scotland forms a relatively isolated ecosystem. The fish community of this lake has remained stable over a long period until a number of introductions in the 1970s restructured its food web.

Biodiversity of a coral reef. Corals adapt and modify their environment by forming calcium carbonate skeletons. This provides growing conditions for future generations and forms a habitat for many other species.

You don’t listen to the science because you are only interested in solutions that will enable you to carry on like before. Like now. And those answers don’t exist any more. Because you did not act in time.
