With the 10:00 a.m. policy any fire that breaks out was to be under control by 10:00 a.m. the following day. This policy was based on the theories about forest management in the plantation forests of Europe. But ecologists have later discovered that burning is essential for the preservation of many natural forest communities. For example the cone of the jack pine and the lodgepile pine will not release seeds unless they are exposed to the intense heat of a forest fire. Fire also helps animals by allowing new vegetation to grow on the cleared soil.…

Although I do not think that the smoke is good for the air, I do however think that the controlled burns are good for the environment in many ways. Fire is a natural resource and forest fires do occur at times simply by nature. When this happens the fire disposes of accumulated debris, it enriches the soil by speeding the nutrient recycle or retard the growth of shrubs or grasses that would otherwise crowd out recently planted seedlings (Yang, 2012). Even though the fire appears to be disastrous, by the following spring, the forest begins new growth. The role that fire plays in shaping ecosystem composition, structure and function includes several ecosystem processes like nutrient cycling, vegetation dynamics, belowground process and soil processes, and water relations. The shaping begins by selecting fire adapted species, and “removing other susceptible species, releasing nutrients from the biomass and improving nutrient cycling, affecting soil properties through changing soil microbial activities and water relations, and creating heterogeneous mosaics, which in turn, can further influence fire behavior and ecological processes” (Chen, 2006, p. 1-2). Despite some of the negatives about fire we must also consider its unique ecological roles within our ecosystem. It is these very reasons why I think…

Banning Catching Fire by Suzanne Collins has good intentions—protecting children; however, children/teenagers should be trusted to make their own decisions about what they read. Books are usually challenged or banned to protect others, for example; violence, sexually explicit or offensive language. Catching fire is said to be challenged because of its violence, anti-ethnic, anti-family, insensitivity, and offensive language. The Hunger Games series was on the 2010 challenged books lists.…

And noise that is potentially dangerous to an adult is even more dangerous to a child because a young child’s ear canal is much smaller than an older child’s or an adult’s, the sound pressure entering the ear is greater. An infant might perceive a sound as 20 decibels louder than an older child or an adult. The shorter length of the ear canal increases dangerous noise levels in the higher frequencies, which are crucial to language development.…

Wildfires provide a slew of associated hazards which require adequate hazard mitigation strategies to protect their communities. First, it is important to examine the human element. Wildfires primarily impact dry vegetation climates, however, most fires are caused by the inappropriate utilization of fire, subsequently causing fires (Smith and Petley, 2013, p. 288). However, wildfires can be also be caused by a more natural means. The natural occurrence of lightning provided an ignition source which can generate fire, especially in large wooded areas under dry conditions. Approximately 15 wildfires were generated last year due to lightning strikes. Drought or severe dry conditions only aid in wildfires in becoming widespread, destroying hundreds…
