Ympäristösykleri

Ympäristösykleri is a Finnish term that translates to "environmental cycle" or "ecological cycle." It refers to the continuous movement and transformation of matter and energy through the Earth's ecosystems. These cycles are fundamental to life on Earth, ensuring the availability of essential resources and the removal of waste products.

Key environmental cycles include the water cycle, the carbon cycle, the nitrogen cycle, and the phosphorus cycle. The water cycle describes the movement of water between the atmosphere, land, and oceans through evaporation, condensation, precipitation, and runoff. The carbon cycle involves the exchange of carbon atoms between the atmosphere, oceans, land, and living organisms, primarily through photosynthesis, respiration, and decomposition. The nitrogen cycle focuses on the transformation of nitrogen through various chemical forms, making it available for plants and other organisms. The phosphorus cycle, unlike the others, does not have a significant atmospheric component and involves the slow movement of phosphorus through rocks, soil, water, and living things.

These cycles are interconnected and operate on various time scales. Human activities, such as industrial emissions, deforestation, and agriculture, can significantly disrupt these natural processes, leading to environmental problems like climate change, eutrophication, and soil degradation. Understanding and preserving the integrity of environmental cycles is crucial for maintaining a healthy planet and supporting life.
