Land reclamation is the process of creating new land from oceans, riverbeds, or lakes. This is often done by filling in these bodies of water with materials like soil, sand, or rocks. The reclaimed land can be used for various purposes, such as agriculture, urban development, or infrastructure projects. Countries like the Netherlands and Singapore have successfully implemented land reclamation to expand their usable land area. While it can provide benefits like increased space for housing and industry, it may also lead to environmental concerns, such as habitat loss and changes in local ecosystems.
