Cleaning the lake

摘要

As the quality of the water from the country's water sources deteriorates, it becomes more complex and more expensive to purify water and to make it safe for drinking. Removal of silt, debris, and overgrown vegetation helps to improve the water quality and to remove the pollutants contained in those deposits. Especially the overgrown plants must be cleared regularly to prevent flooding. Not only do these plants cause flooding, they also swallow up precious water and choke habitats for fish and otheraquatic animals. The growth of the invasive aquatic plants hinders the use of waterways, making them less accessible and ultimately affecting nature-tourism.
