Description: The marine environment refers to the ecological setting that encompasses the oceans and seas of the planet. This vast ecosystem is fundamental for life on Earth, as it hosts an impressive diversity of species, from microorganisms to large marine mammals. The marine environment is not only a habitat for countless forms of life but also plays a crucial role in climate regulation, oxygen production, and the carbon cycle. Key characteristics of the marine environment include its salinity, depth, temperature, and the variability of sunlight that penetrates its waters. These factors influence species distribution and the dynamics of marine ecosystems. Additionally, the marine environment is a vital resource for humanity, providing food, medicines, and recreational opportunities. The health of this environment is essential, as it faces threats such as pollution, climate change, and resource overexploitation, highlighting the importance of its conservation and sustainable management.
