The coral reef structure also buffers shorelines against waves‚ storms‚ and floods‚ helping to prevent loss of life‚ property damage‚ and erosion. Several million people live in U.S. coastal areas adjacent to or near coral reefs‚ and the well-being of their communities and economies is directly dependent on the health of nearby coral reefs. Reefs also protect the highly productive mangrove fisheries and wetlands along the coast‚ as well as ports and harbors and the economies they support. Globally

many sources of energy that are renewable and considered to be environmentally friendly and harness natural processes. These sources of energy provide an alternate ‘cleaner’ source of energy‚ helping to negate the effects of certain forms of pollution. All of these power generation techniques can be described as renewable since they are not depleting any resource to create the energy. While there are many large-scale renewable energy projects and production‚ renewable technologies are also suited to

Module: 121 Natural Resources Assignment Questions and Answers 1. Why do people still use Non-Renewable Natural Resources even though they have many issues. Explain with some examples. Non-Renewable Resources are the resources that cannot be reproduced/grown/generated or used scale which can sustain its consumption. Eg: Coal because it gets exhausted and long time to reform. When we use them and some other examples are LPG/nuclear/natural gas and fossil fuel are natural gas and nuclear energy

ESSAY ON RENEWABLE ENERGY SOURCES. RENEWABLE ENERGY SOURCES FOR THE FUTURE BUSINESS MODEL. Since the discovery of petroleum in 1860‚ fossil fuels have been considered to be the main source of power for our industries‚ cars‚ machinery and way of life. Its availability was never called into question until the crisis of 1973. With the current global growth rythm and with the widespread knowledge that these fossil fuels will eventually be depleted‚ scientists turned toward the research of renewable

it. Coral reefs get hit hard by the temperature of the water getting warmer. “Warming of as little as 1°C causes coral bleaching‚ a state in which the tissues of the coral become colorless because of the loss of the zooxanthellae”(Hoegh-Guldberg‚Donner‚pg. 9‚ par 3). This bleaching can stress the reefs and this can effect important functions of the coral. “Moderate bleaching results in stress that causes reduced growth rates and reproductive output‚ whereas severe bleaching results in coral death
