Essays on Overfishing

Marine trophic cascade is an ecological concept that has attracted a lot of attention in the recent days owing to the increase in overexploitation of marine resources. It is paramount that we gain clear understanding of the impacts brought about by the changes in the food web. Other possible causes include the environmental changes brought about by the climatic changes such as the global warming effects. Recent studies have shown an increase in the overexploitation of the marine top predators that has the potential to initiate a marine trophic cascade. Various scholars have studied the subject and accumulated reports ...

Introduction

Seagrass beds are amongst the most productive marine habitats and their wide-ranging distribution. They provide homes and food sources for many marine animals, prevent erosion and provide nurseries for many commercial and recreational fish species. Despite their importance to the environment, seagrass beds are increasingly being decimated by the results of human activities. The destruction of seagrass beds may have serious consequences on the biodiversity of coastal regions and as a consequence, may negatively impact on commercial and recreational fishing, and ultimately all marine species.

The Cabrillo Marine Aquarium (CMA) tour was both a pleasure trip as well as an opportunity to learn and understand the various seascapes and marine concepts the Pacific has to offer through the lens of the aquarium. For instance, the trip divulged that the oceans are under increasing threat, overfishing, climate change, habitat loss, and marine pollution being just some of the major issues challenging our aquatic world today (Cabrillo Marine Aquarium [CMA]). Partly, because of that, the trip came at an opportune moment to imprint such a reality. The CMA, located on the shores of Cabrillo in San ...
