Canals are man-made waterways designed for various purposes, such as transportation, irrigation, and drainage. They connect rivers, lakes, and oceans, allowing boats and ships to travel more easily. One famous example is the Panama Canal, which links the Atlantic Ocean to the Pacific Ocean, significantly reducing travel time for maritime trade. In addition to transportation, canals also help manage water supply for agriculture. They can direct water to fields, ensuring crops receive the moisture they need. Many cities, like Venice, Italy, are known for their beautiful canals, which serve as both transportation routes and scenic attractions for tourists.
