resources are limited‚ and Earth has a tremendous number of consumers. 3. Geographers observe two major misuses of resources: We deplete scarce resources‚ especially petroleum‚ natural gas‚ and coal‚ for energy production. We destroy resources through pollution of air‚ water‚ and soil. 4. Two kinds of natural resources are especially valuable to human’s minerals and energy resources. 5. Historically‚ people relied primarily on power supplied by themselves or by animals‚ known as animate

Ukraine is distinct for being home to some of the richest natural environments and resources in Europe while at the same time being one of the most heavily polluted countries in the region. Ukraine is one of the least energy efficient countries in the world (Bank‚ 2007). World Bank (2007) composed an inventory in 1998‚ and estimated that total emissions from Ukraine were 246 million tons of CO2‚ and in 2002 the total emissions were 487.7 million tons of carbon equivalents. Ukraine has a severely

A. Identification of Pollutant in the Atmosphere Carbon Dioxide Carbon Dioxide is a colorless gas having a faint‚ sharp odor and a sour taste; it is a minor component of Earth’s atmosphere formed in combustion of carbon-containing materials‚ in fermentation‚ and in respiration of animals and employed by plants in the photosynthesis of carbohydrates. Though living things emit carbon dioxide when they breathe‚ carbon dioxide is widely considered to be a pollutant when associated with cars‚ planes

come out of the ground in forms of liquids‚ gases and solids. These sources include‚ nuclear‚ natural gases‚ and coal. They are considered nonrenewable because they cannot be replenished in a short period. Actually‚ it can take thousands of years in order for them to reproduce themselves. As of now‚ crude oil or (petroleum) is the only naturally liquid profitable fossil fuel. In addition‚ natural gas and propane are normally gases‚ and coal is a solid. If these nonrenewable run out they will become

happens very slowly‚ the environment goes through natural periods of cooling and warming. Global warming causes changes in the climate over time. Global warming has been an issue since 1950. (White‚ 2013) A lot of times global warming is referred to as climate change. Greenhouse gases are the main cause of global warming due to human activity. Contributors to the rise of greenhouse gases released into the air causing global warming include burning oil and gas to power automobiles‚ machinery‚ and heat/energy

human health‚ the presence of air pollutants in high levels can also adversely impact upon wildlife and vegetation. The main cause of a build-up in air pollutants (and subsequent reduction in air quality) is the emission of exhaust fumes from motor vehicles. The quality of air is usually poorest‚ therefore‚ in highly urbanised areas. In Australia this is particularly true of larger cities such as Sydney‚ where fossil fuel emissions from cars contribute to 80 per cent of air pollution. See image 1 Air

(3-7%). Since the industrial revolution‚ human activity has increased the amount of greenhouse gases‚ leading to increased levels of CO2‚ methane and troposphere ozone. Fossil fuels are the world’s largest leading energy and fuel source for most vehicles. When energy is scarce or expensive‚ people can suffer material deprivation and economic hardship. When it is obtained in ways that fail to minimize environmental and political costs‚ these too can threaten human wellbeing in fundamental and pervasive

Ecologically‚ Economically & Globally Automobiles have transformed our planet. There are positive and negative outcomes in all new technological innovations‚ new to the world products‚ and within product line extensions. Automobiles have a severe impact on society’s daily needs of transportation‚ their profit margin capabilities for corporations‚ and seemingly cover our globe. Considering these standards‚ innovators tend to shy away from implementing modernism of transportation. There are simple

Biodiesel can be mixed with any level of standard diesel fuel but the most common is B20 or 20% biodiesel and 80% standard diesel fuel (Hess‚ 2003). 2. Unlike most other alternative energy sources almost all newer diesel engines can run on biodiesel with little or no engine modifications (Hess‚ 2003). 3.
