The Great Lakes Expand the Growth of Canada and North America

- There is no denying the presences of the Great Lakes, not only are they unavoidable, but they have also been a major player in the growing of civilization in North America and Canada. A person would have to live under a rock, no pun intended, to not know about these phenomenons. Most would ask where did these Great Lakes come from. How did they form. How are they beneficial. What are some of the Great Lakes here. Basically, a Great Lake is an extremely large inland freshwater sea, which is amazing since we are surround by oceans occupied with salt water....   [tags: civilization, ecology, survival]

Environmental Impacts of Unsustainable Agriculture in Brazil and Costa Rica

- Since the sixteenth century, foreign dominance over Central and South America has been attributed to farming and plantations. Spaniards introduced the concept of plantation systems to the new world in the island of “La Española” or Hispaniola. From there, it spread through the Caribbean, eventually finding its way into Central and South American countries. Plantation systems were founded on slave labor and brutal methods of exploitation imposed by European colonists on indigenous peoples, and eventually to African slaves, in order to perform labor-intensive farming practices....   [tags: latifundio, history, ecology]

Is There a Correlation Between Pollutants and House Sparrow Decline?

- Is there a correlation between pollutants and House Sparrow decline. Introduction Looking at recent studies and academic research, I am attempting to find a link in pollution, and the declining House Sparrow (passer domesticus) populations world-wide. A number of hypotheses have been proposed to explain the population decline of the house sparrow in urban areas. These include lack of food, particularly aphids, which adults feed to nestlings, pollution from vehicles running on unleaded fuel, increased predation by domestic cats or sparrow hawks (Accipiter nisus), cleaner streets providing reduced foraging opportunities, loss of nesting sites, particularly under the eaves and in the roofs of...   [tags: environmental effects, ecology]

Causes and Impacts of Water Shortage in China

- If you ask any environmentalist in China what the country’s principal issue is, the answer is always: water. China is becoming drier every year—its fresh water reserves declined 13% from 2000 to 2009 (Cho, 2011). It is estimated that every year China has a water supply shortfall of 40 billion cubic meters (Lu and Liao 1, 2011). The question is, why does China have such a serious problem with water. One of the major causes of water scarcity in China is its climate. If you divide China geographically into north and south by the Yangtze River—which runs roughly from Chongqing to Shanghai—80% of the rainfall falls in the south while 20% of the rainfall falls in the north (Cho, 2011)....   [tags: environmental issues, ecology, pollution]

California Wetlands and The Batiquitos Lagoon

- California Wetlands and The Batiquitos Lagoon As the importance of wetland property has been brought to light by ecologists it is a wonder why so much of it is still being destroyed. In California there are development trade- off's that are made that will destroy one wetland while saving another. This will be seen using the Batiquitos Lagoon in Carlsbad, California as an example. In 1987 an agreement was signed with the Port of Los Angeles and the state of California. This agreement allowed part of the Port of Los Angeles to be filled in for commercial development, if the Batiquitos Lagoon was restored....   [tags: Environment Ecology Ecological Essays]

Importance of Recycling at the University

- Importance of Recycling at the University I remember my first semester here at the University and the dark halls of the Bates House Residence Hall. Many a party was concluded with an idea for what to do with the endless piles of cans that had congregated on the floor. One idea, I remember, was to wall someone into his room and another was to see how many we could stand on end without toppling. But, we usually just ended up throwing them in the trashcans in our refuse room. Sometimes out of the five trashcans in the room set aside for trash disposal, three or four would be completely filled with hundreds of cans of various beverages....   [tags: Environment Ecology Essays Papers]

Philosophical Foundation of Ecological Ethics

The comparative analysis of laws and principles of modern ecological science and basic Buddhist thought points to their common intentional direction....   [tags: Ecology Ecological Philosophy Papers]

Greening Businesses: Agents of Change

- Greening Businesses: Agents of Change In the book Ecological Footprint, Wackernagel and Rees state that "U.S. resource consumption is so enormous that if the rest of the world consumed what U.S. residents and companies do, the world would require two more planet Earths" (SDIC, 2002, 1). Businesses generate up to 45% of waste in the United States per year (Inform Inc., 2002, 1). This high level of consumption is largely due to companies that base their activities on unsustainable production, cradle-to-grave life cycles that emphasize: no limit to how much is taken, dependence on non-renewable resources, and little accountability for a product beyond its sale (SDIC, 2002, 1) Since the 1970s...   [tags: Environment Ecology Essays]

Forest Soils on Acid

- Forest Soils on Acid Forest ecosystems are important both ecologically and economically. It is arguable that the most fundamental dynamic of the forest ecosystem is the forest soil. The acidity of forest soils can alter the chemistry, biota, and hydraulics of the soil, and thus, alter the soil formation characteristics and the soil composition. It follows that the acidification of forest soils demands a great deal of research and attention. Forest soils are commonly found to have pH readings of 4-6, even in areas of moderate to low acid deposition (Binkley et al, p....   [tags: Ecology Nature Environmental Papers]

To Save the Earth

- To Save the Earth I wonder how much the front yard of my childhood home is worth. Of course, it's worth less now than before. Once, a stately tree stood in each corner: a tall lilac, a pine, a cherry tree, and a droopy evergreen. My favorite tree lived in the middle. I never knew what kind it was, but every spring it blossomed in delicate pink, and on warm afternoons, I read under its canopy. The front yard no longer looks like that, however. My father removed the lilac bush because it made the lawn too difficult to mow, and cut many of the branches from the pine and my pink-flowered tree so that friends could park their cars on our lawn rather than getting ticketed for parking on the...   [tags: Environment Environmental Ecology Essays]

Simply put, he believed “that population size increases far more rapidly than food and energy resources and as a result, population growth will always threaten to outstrip food supplies” (Kornblum, p. 535). This logic became what we now know as the Malthusian Theory.
