The Gaia Hypothesis is a scientific theory proposed by the British scientist James Lovelock in the 1970s. It suggests that the Earth and its biological systems behave as a single, self-regulating entity. This means that living organisms interact with their inorganic surroundings to maintain conditions that support life, such as temperature and atmospheric composition. According to the hypothesis, the biosphere, atmosphere, oceans, and soil work together to create a stable environment. For example, plants and animals contribute to the regulation of gases like oxygen and carbon dioxide, which are essential for life. This interconnectedness highlights the importance of ecosystems in maintaining the balance of our planet.
