Environmental Issues

Environmental sustainability and waste management is global issue because the world has had lots of contamination and there concern on the kind of environment the humans are surviving in.  It is a matter of concern to every discipline of study that includes designs of whatever kind building construction, engineering, as well as fisheries and manufacturing.  The global warming issue is affecting not only the designers but even farmers thus rising concern to every field of study. Interior...

Mediator between Developed and Developing Countries on the Issue of Global Climate Change The ability of the planet Earth to reflect the radiation and heat it receives from the sun is severely damaged due to the excessive amount of greenhouse gases and pollution in the planets biosphere. The earths surface becomes warmer and climate conditions become extreme. It is an open secret that the Earth cannot anymore sufficiently sustain the needs of its inhabitants. Thanks to the effect of industrialization,...

I strongly believe that the biggest task or challenge to us these days is to conserve energy knowing its increase in scarcity day by day. However, with a little use of brains and creativity we can bring some prominent change and save energy at our houses. At an average house, most of the energy is lost through little air vents present in our doors and windows, if we just check the flow of air with our hands and fix that space, we can easily keep our house warm in winters. We can fill any cracks...

Part 1 Energy Use Review Make a list of all the ways you use energy on an average day.  Be specific about the activities you do.  For example make toast, cook dinner, use the phone, drive car, heat house, etc.  Once you have a list of ten things, determine what type of fuel is being used (oil, coal, natural gas, solar, etc).  If you dont know, take a guess. Activity you do Fuel Type 1. use microwave coal 2. use cell phone   solar 3. use computer nuclear...

The incentive paid by the Manitoba government for purchasing hybrid cars should be increased to 4000 dollars from a current 2000 dollars Two thousand scientists, in a hundred countries, engaged in the most elaborate, well organized scientific collaboration in the history of humankind, have produced long-since a consensus that we will face a string of terrible catastrophes unless we act to prepare ourselves and deal with the underlying causes of global warming. -AL GORE, speech at National Sierra...

There has been notable increase in the importance placed on educational attainment within the society. Education is viewed as a critical requirement to personal and professional development which has led to a myriad of studies seeking to determine the variables that affect attainment and success in education. Understanding the importance attached to students performance and the complexity surrounding it is therefore an important issue in learning and social development. Background The education...

The global rise in total population has brought about an exponential increase in the net demand for consumer goods, energy, and industrial materials. Consequently, households, public institutions, and industrial installations are producing more waste than has never been preceded before in history. There is environment is struggling on one side to maintain a continuous and sufficient flow of resources to meet this demand and the energy required for industrial and home use and on the other to survive...

97 of water on Earth is salty and therefore is not suitable for drinking. The remaining amount of fresh water has always been enough to satisfy needs of the mankind. But rapid growth of the population leads to rising demand on drinking water. Problem of clean water supply shortage has already been faced in many parts of the Globe. Government of the USA is on the alert. Number of states and cities has already initiated measures increasing water use efficiency. Olympia, WA can serve as a good example. The...

Problem 1 Estimate the incremental cancer risk for a 60-kg worker exposed to a particular carcinogen under the following circumstances. Exposure time is 5 days per week, 50 days per year, over a 25-year period of time. The worker is assumed to breathe 20 m3 of air per day. The carcinogen has a potency factor of 0.2 (mgkg-day)-1 and its average concentration is 0.05 mgm3. Given BW  60kg Frequency  5 dayswk, 50 wksyr Duration  25yrs Inhalation rate 20m3day PF  0.2 kg-daymg Ave....

Air pollution in urban areas is a serious environmental problem because it has adverse health problems. It is more prevalent in urban areas due to the fact that more industries as well as other pollutants are positioned in urban sectors. There also very few air purifiers in urban settings and the high population worsens the situation. Studies by Koenig, (2002) reveal that in major cities, the greatest damage of the human health is caused by the inhalation of air pollutants like carbon monoxide,...

The demand for energy is growing tremendously, and this calls upon introduction of new energy sources or improvement on the current sources. An example of such energy source is coal. Coal has been used for a long time, and technological improvement has resulted in clean coal. Clean coal is a word that is used to define technologies and methods that are intended to reduce the environmental impact of utilization of coal as a form of energy source (Coal Can Do It, 2010). These efforts and strategies...

One of the greatest threats to any economy in the world is lack of energy independence. An economy will be vulnerable to any shortage of energy supply in the world market which is followed by great prices increases. Energy independent policy should constitute a core part of any government agenda and objectives. It is asserted that America is the largest consumer of oil in the world. As the third producer of petroleum in the world, America has along journey towards achieving energy independence....

Reducing Greenhouse Gases May Not Be Enough to Slow Climate Change Website sciencedaily.com URL  httpwww.sciencedaily.comreleases200911091111083055.htm Part One New Article Review The article Reducing Greenhouse Gases May Not Be Enough to Slow Climate Change talks about the need to broaden the management options being used to address the problem of climate change by moving a step higher beyond reducing greenhouse gases.   Since mid 20th century, about 50 of the global warming experienced...
