A canal is a man-made waterway designed for navigation, irrigation, or drainage. Canals are often constructed to connect two larger bodies of water, such as rivers or lakes, allowing boats and ships to travel more easily. They can also help manage water levels in agricultural areas, providing essential irrigation for crops. Canals have been used for centuries, with famous examples including the Panama Canal and the Suez Canal. These waterways play a crucial role in global trade by facilitating the movement of goods between different regions. Additionally, canals can enhance local ecosystems and provide recreational opportunities for communities.
