Aquatic environments are areas where water is the primary medium for life. These environments can be classified into two main types: freshwater and marine. Freshwater environments include rivers, lakes, and ponds, while marine environments consist of oceans, seas, and coral reefs. Each type supports a diverse range of organisms, from tiny plankton to large mammals like whales. These environments play a crucial role in the Earth's ecosystem. They provide habitats for countless species, help regulate the climate, and are vital for human activities such as fishing and recreation. Protecting aquatic environments is essential for maintaining biodiversity and ensuring the health of our planet.
