To conserve and sustainably use the oceans, seas, and marine resources for sustainable development.
Oceans, seas, and marines are important for the Earth's ecosystem. They cover more than two-thirds of the earth’s surface and contain 97% of the planet’s water. For human beings, aquatic ecosystem is used as sources of water, food, materials, and other recreation purposes. However for animals, water bodies acts as habitats for fishes, sharks, dolphins, and many more. According to the World Register of Marine Species (WoRMS) the total number of marine species known to us is about 240,000 species (2021 census), which proves how big the diversity is underwater. One of the organism that lives underwater is phytoplankton. Phytoplankton is a microscopic plant and is a key part of oceans and freshwater ecosystems. Phytolanktons will absorb carbon dioxide (CO2) and release oxygen.
Nowadays, oceans, seas and marine resources are increasingly threatened, degraded, or destroyed by human activities, reducing their ability to provide crucial ecosystem needs. The biggest threats are climate change, marine pollution, unsustainable extraction of marine resources and physical alterations and destruction of marine and coastal habitats and landscapes.
