The earth’s oceans provide an enormous range of resources and affect the quality of life as we know it. The oceans cover approximately 70 percent of the surface of the earth and have a cyclical effect on weather‚ e.g. temperature‚ precipitation and air quality. Regardless of your views on global warming‚ the fact remains that humans have an impact on the marine ecosystems through waste from chemicals and debris polluting this vast renewable resource. Based upon current scientific evidence‚ emissions

Describe how igneous activity can affect the landscape Igneous intrusions form when cooling‚ crystallization and loss of gases cause a once fluid magma to solidify. Most rocks that form intrusions originate as either granitic or basaltic magma. Granitic magmas are low density and small quantities‚ just a few kilometers wide‚ rise slowly through the earth’s upper crust‚ pushing existing country rock aside. However‚ very large granite masses‚ which can be up to 1‚000 times larger‚ are formed when magma

Agriculture in the Amazon Rainforest Throughout a hundred centuries people have worked hard to sustain productive agriculture and dense human populations. Certain forms of agriculture are possible‚ and should be considered sustainable‚ for the economic development of tropical rainforests. For thousands of years humans have created a disturbance in the rainforests by creating areas of concentrated diversity of species within the landscape. The Indigenous people of the Amazon fostered palm forests

Ecosystem Components The Tarkine rainforest is located off Australia‚ on an island known as Tasmania. The Tarkine rainforest is the second largest temperate rainforest in the world. Temperate rainforests are extremely rare. It runs continuous for more than 70 kilometers and contains the Rapid‚ Keith‚ Donaldson‚ and Savage River systems. Globally‚ this is one of the most significant rainforests‚ which is temperate‚ left of the plant. The Tarkine rainforest contains three out four of Tasmania’s

How Humans Impact Marine Ecosystems Earth consists of many complex organisms that share and benefit from all of what the world has to offer. Conservation and protection of marine life is becoming more significant as humans better understand the importance of the oceans and how people have an affect on them. Just as people treasure and protect areas of land it is just important to treasure and keep the oceans safe. Marine life is becoming increasingly damaged because of threats from human activity

Amazon Rainforest: Clear-Cutting the Myths. There has been talk for years about the destruction of the Amazon rain forest. However‚ the Amazon is one of the most intact and least-endangered forests on the planet. The claim that the rain forests are being destroyed "at a rate of 20 football fields a minute" is false.

Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting

like soil‚ climate and water. Include all of that along with the complex interrelationships among the organisms and the environment‚ and we are closer to an actual understanding of this ecosystem. Here we will be studying the biotic and abiotic components of two major freshwater ecosystems we’ve visited- the Ampang lake and the Gombak river. Biotic factors consist of the living things that shape an ecosystem (Library.thinkquest.org). After examining the lake and river ecosystems‚ we only found
