Sea turtles graze on the sea grass found on the ocean floor, helping to keep it short and healthy healthy sea grass in turn is an important breeding ground for many species of fish, shellfish.
And a growing body of scientific research suggests that light pollution can have lasting adverse effects on both human and wildlife health when does nuisance light become a health hazard this, in turn, has implications for the wildlife that depend on trees for their natural habitat research on insects, turtles, birds, fish, reptiles, and.

In sea-turtle management, assessment models are used to evaluate the status of the population relative to recovery goals, to compare relative efftects of different human activities and natural stressors on populations, and to determine whether human activities that result in turtle mortality will impede recovery or increase extinction risk. Complex and secretive life of sea turtles (they spend most of their lives at sea), make it all the more difficult and expensive to study sea turtles to devise strategies to protect and conserve them. Chemical, biological, or physical cleanup and reconstruction of severely contaminated or degraded sites to return them to something like their original topography and vegetation reallocation to use a site (and it's resources) to create a new and different kind of biological community rather than the existing one.

This is why harmful effects of human waste, production, and consumption can have such drastic effects on certain ecologies and biospheres a major concern right now is the problem of overfishing ocean overfishing simply means catching fish from sea at rates too high where fish stocks become too depleted to recover. Help save wildlife by 2025 as many as one fifth of all animal species may be lost, gone forever for the most part letting nature take its course rather than relying on human intervention they involve taking turtles out of their natural habitats and exposing them to many dangers, not to mention an enormous amount of stress. Although these threats to sea turtles and destruction of their habitats seem almost too big to overcome, there are many things within our control that can be changed greater public awareness and support for sea turtle conservation is the first priority.
