Introduction As of now the Earths ocean is home to over 230‚000 species of marine plants and animals. Today the oceans are at risk because of human activities. The main problem is climate change which leads to other problems within such as ocean acidification and pollution; these effects can all have an ever lasting impact on what’s in the ocean and what’s out. Paragraph 1: Climate Change (ocean acidification‚ CO2 ‚etc.) One of the main dangers of the oceans today is climate change

people didn’t have good techniques for successful fishing compared to today’s fishing equipment. Therefore‚ because of efficient equipment and the significance of fishing in our society‚ many kinds of fish are in danger of disappearing. Overfishing is a very big problem today. The Sardine is one of the most useful kinds of fish. It is a very small fish compared to all the big fish in the sea. The article‚ “Sea Food Crisis: Time for a Sea Change” by Paul Greenberg‚ from National

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

population-control measures‚ the demands are bound to grow.Industrialized countries‚ with higher living standards and greater numbers of cars‚ produce far more air pollution and greenhouse gases than developing countries. 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

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.

1 Title: The Marine Biome #2 Biome Description and Definition The Marine Biome is made of all the oceans in the world. It holds many diverse species in animals and plants and since it is so enormous‚ there is some species that have not been discovered yet. The ocean is a mysterious thing because it is different in each part of the world‚ the climate depends on the location and the location depends on what species are located in that part. Australia is home to the coral reef‚ where today it is
