Marine development refers to the process of utilizing ocean resources for various purposes, including economic growth, environmental sustainability, and scientific research. This can involve activities such as fishing, aquaculture, and marine tourism, which aim to balance human needs with the health of marine ecosystems. Additionally, marine development encompasses the construction of infrastructure like ports and offshore wind farms, which support energy production and transportation. It also includes efforts to protect marine habitats through marine protected areas and sustainable practices, ensuring that ocean resources remain available for future generations.
