Streamlining equipment is essential for divers aiming to minimize their impact on the marine ecosystem. When divers have streamlined or well-fitted gear, they can maneuver more efficiently through the water. This reduces the chance of kicking up sediment, disturbing the seabed, and accidentally damaging fragile coral reefs and marine organisms. Efficient equipment design also lessens the likelihood of the diver causing turbulence and habitat destruction while swimming or adjusting their position in underwater environments.

In contrast, staying close to the bottom can increase the chance of disturbing sensitive habitats. Using bright lights in shallow water can attract marine life, which may lead to unintended consequences for local ecosystems. Diving without any equipment, while it may seem like a way to limit impact, is impractical for most divers and does not necessarily equate to reducing disturbance to the ecosystem. Thus, streamlining equipment stands out as the most effective practice for responsible diving while preserving marine health.
