5. Low Fecundity: Species produces few offspring. Note: species which care for their young either before birth (long pregnancy) and/or afterwards have fewer offspring than those who do not.
6. High Human Value: Species has characteristics that make it valuable to humans. Many animals have been hunted to endangerment, or even extinction, for their beautiful plumage or fur. Wild plants and fungi may also be over-harvested if they are particularly tasty or contain useful medicine.

Economics of Forestry Timber is the major product currently harvested from forests. Timber is used in a variety of products ranging from houses to paper and paperboard products. Long ago it seemed as if the supply of wood from forests was abundant and as if there would always be enough to provide everything that we could possibly need. However, recently we have realized that this is not the case. Timber
Biodiversity in Lake Baikal We are in a world where there is a continuous exploitation of natural resources and very little care about the environmental consequences. Rapid industrialization has created havoc to the delicately balanced ecosystems. The effect that human population has had on global ecosystem is certainly undeniable and global biodiversity is being seriously challenged. The rapid deforestation of Amazon forest, the irreparable damage that we have done to the
living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things. Biology is a very broad field that encompasses the study of characteristics of living things. It includes
operation and data management of the water-authority with a specific focus on the ability to provide a sustainable water supply for the next century in the Caribbean. This literature review will examine previous studies (both qualitative and quantitative) of water sustainability and specific problems related to water quality, such as the build-up of nitrogen in the water supply. It will also review ways to assess water quality through the
