One of the most common human activities that harm the coral reefs is overfishing. Overfishing can eliminate large populations of fish that are crucial for the health of coral reefs. Large nets and anchors can also cause damage to the reefs from being dropped into the water from fishing boats. Uneducated tourists that visit the areas

Developed countries also contribute to overfishing and deforestation . But these countries can reduce serious environmental hazards by using technology such as smokestack scrubbers‚ emission systems‚ and waste-water treatment plants. Although developing countries consume a far smaller percentage

Consumers‚ fish for example‚ metabolize‚ and release as chemical energy to convert into mechanical energy. The ecosystem distributes energy to living organisms through heat energy. Decomposers break down dead organisms and deplete them of their

Current and Future Status of Coral Reefs in Malaysia Abstract: Coral reefs‚ also known as the rainforest of ocean‚ are the most productive and biologically rich ecosystem on earth (McAllister‚ 1995). Coral reefs are an important source of food and income to millions of people that are living near coast (Burke‚ et al.‚ 2002). There are about 540 species of hard corals that have been identified in Malaysia in total and there are more than 90% of the country’s reefs are situated off the coast of

In this photo‚ a diver is attaching a sensor to track a monster Echizen jellyfish‚ which has a body almost 5 feet across‚ off the coast of northern Japan. Jellyfish are normally kept in check by fish‚ which eat small jellyfish and compete for jellyfish food such as zooplankton‚ researchers said. But‚ with overfishing‚ jellyfish numbers are increasing.
