Question
Overexploitation, when so many individuals are removed that a population can no longer sustain itself, has been a major contributor in the decline of land-based species over the last 50 years, and the primary driver of biodiversity loss in marine systems. The decline or extinction of a single species can also change the composition of other species within a habitat, including a shift in species dominance or decrease in the survival ability of the remaining species. Other problems can occur when overexploitation leads to a drop in nearby populations. For instance, when overfishing of one species leads to a decline in by-catch or drives the market to overexploit another, previously unexploited, species. The most overexploited groups of species are marine fish and invertebrates (which are fished for food), a variety of trees, animals hunted for meat, and plants and animals harvested for medicinal use and trading. Rarity can help drive up the price for trading, and popularity also lends a hand: cacti, orchids, and many tropical aquarium fish are threatened with extinction due to over-collection for commercial purposes. There has been some success at the international level with the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which aims to ensure the international commercial trade in species of wild animals and plants does not threaten their survival.
