surface. It wasn’t until my first semester at West Hawai’i Community College while taking a history class under Dr. Stevens, that I discovered our own local ecosystems are in danger of habitat loss. I had always heard about deforestation and the anthropogenic destruction of our environment, but never did I imagine such a beautiful and secluded place like Hawai’i, silently submitting to our neglect. Dr. Steven played a tremendous role in my commitment to restoring Hawai’i’s native ecosystems by orchestrating

Previous studies have shown that exposure to human by ozone is effective to health and it is increasing worldwide. Air pollution is the serious global threat which is increasing continuously and the ground level concentration of ozone is major problem in present and also in future. Presents projected average daily 8-h maximum ozone levels for future using the raw and calibrated climate model outputs. The 95% projections intervals accounts for uncertainties in the associations between daily ozone

I think it is not a myth that the rainforest was once pristine. Although Mann's study suggests that large swathes of the Amazon where farmed intensively, I find his evidence dubious and am more inclined to agree with Barlow. Barlow provides evidence that only a small fraction of the rainforest was altered by pre-Columbians, citing that although there would have been high impact activities such as ADES, settlements, enrichment planting, these would have only taken place on small scale when compared

amount it fairly low compared to other fluxes of phosphorus. In contrast, the nitrogen gas (N2) accounts for 78% of atmospheric gases on Earth. It is noteworthy that the N2 fo The balance of these two cycles is being constantly disrupted by anthropogenic interventions. The most prominent evidence of nitrogen imbalance is water eutrophication, commonly caused by fertilizer and waste runoff. The reason why the N2 atmospheric nitrogen compound is not suitable for use, is because the two N atoms are

pollution has been a major problem throughout world for the past 5 decades i.e. a few years after the industrial revolution. There are two types of air pollutions a) Natural and b) Anthropogenic, of which the natural causes (volcanoes, forest fires and tornadoes) are not in the control of man (Mosley 2010). Anthropogenic air pollution on the hand is a type of anomaly in the atmosphere where foreign objects are released into the air entirely by man and his activities (Industries, transport) and are

and precipitation etc. According to the IPCC’s Synthesis Report, “Anthropogenic greenhouse gas emissions have increased since the pre-industrial era, driven largely by economic and population growth, and are now higher than ever. This has led to atmospheric concentrations of carbon dioxide, methane and nitrous oxide that are unprecedented in at least the last 800,000 years. Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are

The complex processes of urbanisation overarches and entails a set of social, cultural, economic, political, environmental and technological functions that result in sprawl and densities, proportional to core size and settlement. Further implicating the extensive use of natural resources from fringes and rural spheres within city limits to be consumed and then later in turn converted into waste. Urban ecosystems are therefore, complex multifaceted systems that require a burdensome amount of natural

Although most of this essay focuses on the western relationship with nature, it is important to explore the construct of nature in other societies. This avenue is imperative to this essay as many of the environmental and social issues that are present in today’s world are entangled by a certain subset of Western or European set of values denoting how to interact with the environment. These generally center around the notions of ‘development’ and ‘modernity’. Reading widely on the topic, one finds

Presently, climate change is one of the largest threats to the Earth, and all recent research points to an anthropogenic cause. As humans burn fossil fuels, carbon dioxide and other greenhouse gases enter the atmosphere where they remain at unprecedented levels. As a result, greenhouse gases absorb infrared radiation emitted by the Earth and trap the radiation as heat, which should have left the atmosphere and entered outer space. This heat causes a gradual increase in the average temperature of

warmest in the United States since national record keeping began in 1895. This has been the warmest decade and it just goes on and on. Global warming is a natural episode in the earth´s life cycle. However, it is currently being speed up mostly by anthropogenic causes such as pollution, and the emission of greenhouse gases that get trapped into the atmosphere, causing the temperature to rise, therefore causing global problems such as climate change, natural disasters, melting of glaciers, dying of species
