Merielämä

Merielämä is a term that refers to the collective life and ecological processes found within oceans and seas. It encompasses the vast diversity of organisms, from microscopic plankton to the largest whales, and their intricate interactions with the marine environment. This environment includes a wide range of habitats, such as coral reefs, deep-sea trenches, kelp forests, and open ocean pelagic zones, each supporting unique communities adapted to specific conditions of temperature, salinity, pressure, and light availability.

The health and functioning of merielämä are critical for the planet's overall well-being. Oceans play a vital role in regulating Earth's climate by absorbing carbon dioxide and producing a significant portion of the world's oxygen through photosynthesis by marine plants and phytoplankton. They also serve as a major source of food and resources for human populations, supporting fisheries and other industries.

However, merielämä faces numerous threats. Pollution, including plastic waste and chemical runoff, degrades water quality and harms marine life. Overfishing depletes fish stocks and disrupts marine ecosystems. Climate change leads to ocean warming and acidification, which can have devastating impacts on sensitive species and habitats like coral reefs. Conservation efforts and sustainable practices are essential to protect and preserve the biodiversity and ecological services provided by merielämä for future generations.
