What is one modified finning technique that helps protect the environment?

The modified flutter kick with legs higher than the body is beneficial for environmental protection while diving. This technique allows divers to maintain a streamlined position in the water, which reduces their overall disturbance to the surrounding environment. By keeping the legs elevated, divers can minimize contact with the seafloor, thereby decreasing the risk of stirring up sediment and damaging fragile marine ecosystems such as coral reefs.

This approach is particularly important in areas where delicate habitats are present, as it helps preserve the health of these ecosystems by limiting physical impact. Enhanced buoyancy and control achieved with this modified kick also contribute to energy efficiency, allowing divers to move gracefully without excessive propulsion, which could otherwise lead to the dislodging of organisms and sediment.

In contrast, other techniques like a powerful downward kick could lead to increased disruption of the underwater environment and sediment disturbance, making them less environmentally friendly. Hence, the choice of a modified flutter kick with legs positioned higher is aligned with responsible diving practices that prioritize the health of marine habitats.
