1. Increased Energy Use: Building a fence requires the use of energy to power tools and equipment, as well as to manufacture any materials used in the construction. 2. Loss of Habitat: Fencing off the lake may reduce available habitat for wildlife that previously used the lake as a source of food and shelter. 3. Damage to Landscape: Heavy machinery and tools may cause damage to the lake's surrounding landscape, negatively impacting the aesthetic of the area. 4. Pollution: The construction process may involve the release of pollutants into the air, water, and soil. This can have negative impacts on the environment. 5. Cost: Fencing can be expensive and its maintenance may require additional funds.
