decline in mortality rates over the past decades. Both of which are fundamental causes of the current overpopulation issue. Another major factor is the lack of education amongst people. Specifically‚ people are not educated on the importance of preventing population from growing excessively‚ nor are they aware of the downsides to overpopulation. Hence population size is not properly controlled. Although an increase in population is equivalent to an increase in human resources‚ which is beneficial

For example‚ many of the best edible fish such as the piracacu have had their populations greatly reduced by overfishing without any seasonal control to avoid the breeding season. The use of gill nets‚ dynamite and other environmentally unacceptable methods of fishing is having a drastic effect on the product that is the best source of protein in the region. Already

ECOSYSTEMS AT RISK – CASE STUDY 2 PART 1: CORAL REEFS – OVERVIEW Coral reefs are often referred to as “the rainforests of the sea” because of they form some of the most diverse ecosystems on Earth. Its massive structure is formed from coral polyps (tiny animals that live in colonies) that support approximately 25% of all known marine species by providing essential habitats. Factors affecting reef development and survival include temperature‚ light‚ sedimentation and salinity of the water. Without

Do you think it is possible to overuse our ocean resources? It is possible to overuse our ocean resources. We can drill and use an excessive amount of oil from the bottom of the ocean. This resource is made up of dead fish and other creatures that sink to the ocean floor and as sediment builds up the dead animal remains decompose and heat up to form the oil and natural gas. This can take up to thousands of years to form and if humans use too much oil we will have to wait another thousand years to

but also the surrounding creatures that share these systems. The question that we want to answer is do we change our actions to protect the Great Barrier Reef? Overfishing is one of our habits that has had a negative impact on the Great Barrier reef by causing major disruptions to the food chain. A domino effect results when overfishing occurs in the Great Barrier Reef. Fishing for a particular species affects not only that species‚ but it also affects the animals and or plants in both directions

approximately 2050‚ there will be no fish in the sea. Overfishing is a serious issue that involves taking wildlife at increasingly higher rates than the species can replace. Because this issue is hidden under waters‚ people do not realize the seriousness nor do they realize the consequences. This film highlights some of the well-known species‚ such as bluefin tuna and cod‚ which are likely to reach extinction if overfishing continues. The overfishing of bluefin tuna is caused by the increase in demand

Land based pollution that runs into the sea is a major threat to coral reefs. 2. Marine debris which is made up of objects discarded by humans affects corals greatly. II. Overfishing is very common as corals provide a livelihood for humans. * ways in which overfishing occur 1. Blast fishing destroys
