In tropical regions, freshwater species were especially hard-hit; the index shows they suffered a 35-percent drop between 1970 and 2000." Terrestrial species are affected by over-farming and deforestation: the change has been swift and alarming: The world's wildlife declined by 27% since 1970 overall (Humans blamed, 2008, CNN). Even domestic animals have suffered from humanity's engineering of the environment. Many cannot life in the wild without the help of humans, given how selective breeding has reduced the capacity of the dog, the cat, and the horse to forage for itself. In the case some animals raised for consumption, such as cattle, humans force them to eat an unnatural diet of corn. Corn-fed cows are fatter than grass-fed cows, but they must be fed antibiotics to be able to digest...
In general, domestic animals have smaller brains and are fatter and less hardy than their wild counterparts: domestication renders them useful to humans, not better-adapted to survive. This parallels how humans have attempted to adapt the world to our needs, rather than adapted our needs to the world and harmed and in some cases destroyed many wild species.

brevis blooms are not a new phenomenon, and fish kills that result from red tides caused by K. brevis in the Gulf of Mexico have been described in the scientific literature since 1960 or so and have been reported anecdotally for more than two centuries (Naar et al. 2002). In this regard, Backer and her associates (2005) emphasize that, "The human health effects from consuming shellfish with high concentrations
Urbanization Ecological Problem Grade Course Walking on grass while it rains, looking at the blue sky and hearing the bird chirp, and letting cool breeze touch the skin are amongst some of the most refreshing moments which one would loathe. The refreshment and serenity arising from such moments rather define environment as a miraculous beauty. Despite the ease and satisfaction associated with nature, ecological problems go hand in hand with the reality of
Stream Degradation and King County' Salmon Population King County in Washington State is home to some of the most significant spawning beds in the nation for several major species of salmon, such as the endangered steelhead and Chinook (or King) species. As a result of Washington's urbanization over the preceding years and decades, the purity and integrity of King County's streams and rivers have been degraded and the waterways contaminated (Morley,
Trees cover nothing less than one-third of the earth's surface, and it is estimated that around 3 trillion trees exist worldwide. Forests are found in different climates and locations, and they exist in wet, dry, sweltering and bitterly climates. Each of these forests types have the natural peculiarities that allow them to develop in their respective climates (Motivans). Unfortunately, in the past few decades, there has been an enormous level
water pollution in Lake Huron Lake Huron is one of the great lakes that face the challenge of pollution in Ameica. Pollution in the lake prompted the binational partnership aimed at safeguarding areas of concern that have high quality habitats. According to the environmental protection agency, the partnership undertakes remedial action plans aimed at combating the threat fish, wildlife and public health that emanate from water pollution (EPA, 2012).
