The ecosystem on the brink is that once an ecosystem is disturbed or destroyed it unlikely to return to its original state. Human activities such as fishing, converting land into farms and cities, or warming the planet, humanity is putting tremendous stresses on the world’s ecosystems. Researchers used a mathematical models to display on how one or two species will affect the ecosystem. It was found out that food webs can be staggeringly complex because there is a weak link and a strong link, weak link may thus keep species from driving one another to extinction and strong links keep eating to only one species. For example, like cod, once it was decreased, many species that depends on it were harmed. Many researchers are trying to put cod to regenerate and bring the ecosystem that once destroyed back to original state but cod has been decreasing because many species had been eating the eggs of cod.
After reading this article, all our actions led to a major change to the ecosystem and to humans as well. Change in the ecosystem because some species depend on another species to survive and cause to change if another species were gone and the whole cycle will be ruined. Also, the change in human as well, fishing, hunting and many different technique to hunt animals will affect us, because we are taking animals that is helping in the environment and if we over do our hunting then the environment will change and it will change us humans. |
