Canals are man-made waterways designed for various purposes, such as transportation, irrigation, or drainage. They connect different bodies of water, allowing boats and ships to travel more easily. Canals can be found in many countries and often feature locks, which help manage changes in water levels. One famous example of a canal is the Panama Canal, which connects the Atlantic Ocean to the Pacific Ocean. This engineering marvel significantly reduces travel time for ships, making global trade more efficient. Canals also provide recreational opportunities, such as fishing and boating, and can enhance the beauty of landscapes.
