Some would consider Max impulsive, irresponsible, or just plain serendipitous because he loved to shower his family with unexpected surprises. He hid candy in his overcoat pockets; when he arrived home from work, the seven took turns guessing which pocket held the treats. The ultimate serendipitous occasion occurred when he surprised them with the news they were getting a five-foot deep, twenty-two foot wide, above ground swimming pool. Only one other house in the neighborhood had an above ground

result is an increase in asthma and cancer in the lungs. Urban air pollution is set to become the biggest environmental cause of premature death in the coming decades, overtaking even such mass killers as poor sanitation and a lack of clean drinking water, according to a new report. Both developed and developing countries will be hit, and by 2050, there could be 3.6 million premature deaths a year from exposure to particulate matter. Air pollution is a primary problem in urban areas and for individuals

Dr. Roark’s talk, Deep-Sea Coral Perspectives on Ocean Circulation and Mississippi River Drainage Basin Changes, discusses the correlation between agro-industrialization and land-use changes and how these factors influence ocean biogeochemical cycles. He uses multiple elements, but mainly radiocarbon and Rhenium accumulation in deep-sea black corals to determine ocean circulation. The black corals retain these elements because the feeding matter they take in is exported organic matter from the

2.1 How to manage the site drainage and its importance. Site drainage management is aim to safeguard the house inhabitants and protect the house from several damage cause by surface water and both internal and external inappropriate moisture (Master builders, 2009). Site drainage management is a very important part of the design of footing system. It is because the site drainage could influence the success of the footing system, the maintenance of the site drainage influencing the economic life

Liquid water is the most important factor for life, as we know it. Water is abundant in the galaxy, it is found in cold dense molecular stars as well as hot stellar atmospheres. Liquid water exists at a large range of pressures and temperature. Liquid water is the best solvent for life to emerge due to its large dipole, the ability to form hydrogen bonds, and to stabilize macro molecules. It is able to orient hydrophobic and hydrophilic molecules and is a strong polar and non-polar solvent. This

that blazed overhead on that hot, summer day. Children, with smiles just as bright as the sun, splashed in the crystal-clear waters, their heads bobbing above the surface. A small girl, grinning from ear to ear, jumped into the pool, causing waves to sweep over the other children. Although everybody re-emerged sooner or later, I still shivered at the sight. Another wave of water splashed across the pavement, feet away from the grassy lawn where I sat crisscross applesauce. Attached to a canopy across

Do the economic benefits of the Alberta tar sands outweigh the environmental costs? World needs energy and Alberta need the oil sands to strengthen the economy. When considering Canada, especially Alberta has been in the oil market, bringing heaps of economic benefits to the country. Besides, energy has turned out to be one of the essential and basic needs, mandatory for the economic progress of a nation. Depending on consumption of the main energy sources, oil is used in a percentage of around

Water! The band Papadosio has once sang, “Please remember that water comprises over 70 percent of the mature human body, and covers the same amount of our planet. Water is the very source of all life.” This is an important statement because it shows how significant water is to everybody and every creature on earth. Water shapes everything, and one thing in particular water shapes is the state of Michigan. Michigan is over 50, 000 miles of land between the two peninsulas, and it is surrounded by

contributes to the river flooding so often is the ice melting in the spring. The Red River flows northward, and when the ice thaws, it also runs northward along the valley, causing runoff from the southern portions of the river. When the ice, river water, and runoff all join together in the

Sacred Headwaters region is ecologically important since it is the habitat for many wildlife, including caribou, wolves and grizzly bears. The great amounts of salmon and steelhead also spawn in this area. It is not only an environment that abundant in biodiversity, but also a place with an abundance of natural resources, such as, mineral, coal and coalbed methane. (Suzuki, 2013) Although Sacred Headwaters is rich in natural resources, those resources are limited, continuing extracting resources
