Overfishing, Sharks, and Biodiversity
[ send me this paper ]
An 8 page overview of the impacts of overfishing on sharks and other species, some of which might not be immediately obvious as to their relation with the shark. Emphasizes that our oceans are fascinating testaments to the complexity and interrelationships of living organisms, that they are comprised of a number of interrelated components, each with its own ecological value. Details possible impacts to both open water diversity and coral reef biodiversity as a result of the overfishing of sharks. Bibliography lists 8 sources.

Philodendrons: Environmental Considerations and Care
[ send me this paper ]
An 8 page overview of the considerations which must be made when growing Philodendron. Devotes considerable attention to growth preferences and the physiological reasons behind those preferences. Concludes that while Philodendrons are among the easiest of houseplants to grow, attention must be paid to the type of soil that they are planted in, the presence of absence of surfaces upon which the vine can trail, appropriate soil water levels and humidity, and the provision of a clean environment which discourages pests. Bibliography lists 14 sources.

Positive Aspects Combining Nature and Technology
[ send me this paper ]
5 pages. The introduction of bioengineering into the mainstream of science and technology has been nothing more than a natural progression. To be sure, there is a definite need for such advancement if humanity is to endure the climate changes that are affecting the very food crop upon which people depend. Additionally, the advantages of bioengineering within the medical industry have proven indispensable for its groundbreaking discoveries and applications with regard to sustaining health in the human body. There is no question that bioengineering represents mankind's ability to overcome some of nature's most ravaging aspects in order to continue -- and even enhance -- life as we have known it thus far. Without the influence of bioengineering, humanity's food supply and medical advances would suffer greatly. Bibliography lists 5 sources.
