Biodiversity is a term used to describe the enormous diverseness of life on Earth. It can be used more than specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists take estimated that in that location are around 8.7 million species of plants and animals in existence. Withal, but around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today accept evolved unique traits that make them distinct from other species. These differences are what scientists use to tell i species from another. Organisms that have evolved to be and so different from i another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species.

Scientists are interested in how much biodiversity in that location is on a global scale, given that at that place is nonetheless so much biodiversity to find. They also written report how many species exist in single ecosystems, such equally a forest, grassland, tundra, or lake. A single grassland can contain a broad range of species, from beetles to snakes to antelopes. Ecosystems that host the most biodiversity tend to have ideal environmental conditions for constitute growth, like the warm and wet climate of tropical regions. Ecosystems can besides contain species too minor to run across with the naked center. Looking at samples of soil or h2o through a microscope reveals a whole world of bacteria and other tiny organisms.

Some areas in the world, such every bit areas of Mexico, South Africa, Brazil, the southwestern United States, and Republic of madagascar, have more biodiversity than others. Areas with extremely high levels of biodiversity are called hotspots. Endemic species—species that are merely found in one item location—are also found in hotspots.

All of the Earth's species work together to survive and maintain their ecosystems. For case, the grass in pastures feeds cattle. Cattle then produce manure that returns nutrients to the soil, which helps to grow more grass. This manure can also be used to fertilize cropland. Many species provide important benefits to humans, including food, article of clothing, and medicine.

Much of the Earth'due south biodiversity, however, is in jeopardy due to human consumption and other activities that disturb and even destroy ecosystems. Pollution, climate modify, and population growth are all threats to biodiversity. These threats have caused an unprecedented ascent in the rate of species extinction. Some scientists estimate that one-half of all species on Earth will exist wiped out within the adjacent century. Conservation efforts are necessary to preserve biodiversity and protect endangered species and their habitats.
