Biodiversity and ecosystems work hand in hand with one another. Without one, it is unlikely to have a thriving version of the other. Biodiversity is defined as the variety of species that are found in a natural state. Many consider this to be talking about species of animals, however, this includes ecosystems and genetic diversity. Chapter six tells how biodiversity contributes to what we know as biological wealth. This can largely determine how one sees a country’s wealth and economical capital…

For acknowledging in its Integrated Management System Policy that sustainable development is one of the foundations of its wood and pulp production activities, CENIBRA develops a number of actions aiming at protecting the existing natural resources of its lands, as well as enhancing the environmental awareness among its employees and the communities. By adopting operating practices based on procedures derived from standards ISO 9001-2008 and 14001-2004, and an extensive natural resource…

Provide one example of each. Opportunistic populations are small individuals, with a short life span that are fast to mature, and they have many offspring which they provide little or no care for. Opportunistic species exhibit exponential growth. The populations typically have a high dispersal capacity. An example of an opportunistic species would be the dandelion. Equilibrium populations are large individuals with a long life span that are slow to mature. They have…

pollution and degradation to its health is correlated with the activities. Modernization and its vices that include, urbanization and industrialization, have taken a very harmful and significant toll on the environmental health of the planet. The rising population across…

A refugee is an individual who leaves their home country owing to insecurity while seeking asylum in a foreign country that hosts them. According to Collier (2013), refugees are only beneficial to their host country to a given extent beyond which they become a burden. Hence, refugee numbers must be regulated to maximize the benefits of refugees while minimizing the demerits of refugees to the host country (Farazmand, 2014). This essay will discuss that the beneficial or disadvantageous…

Downstream of dams, marked changes in fish populations occur as a consequence of blockage of migration routes, disconnection of the river and floodplain, and changes in flow regime, physiochemical conditions, primary production and channel morphology(McCartney, 2009, pg. 128). Due to the changes in the fish population caused by dams, the 1996 International Union for Conservation of Nature (IUCN) Red List of Threatened Animals includes…

Environmentalism is the political and philosophical position that the health of the natural world should be an item of social concern(CITE). Environmentalism relates to conservationism, the belief that natural resources should be treated carefully so as to produce the greatest benefit, and preservationism, the belief that untrammeled nature has inherent value, whether ecological, aesthetic, or spiritual, and therefore that some landscapes should be left undeveloped. (CITE) Within the history of…

The theory of environmental determinism is a prominent concept in the discipline of geography that has impacted the course of modern geographic thought as we know it (Peet 1985; Heffernan 2009). In brief, the premise of environmental determinism, also known as geographical determinism or climatic determinism, asserts that the physical environment, including climate, predisposes states, societies, and individuals towards specific development paths (Agnew and Livingstone 2011). Environmental…

Ecotourism can be described as responsible travel to natural areas which not affect the natural resources and preserve the benefit of local populations (TIES, 2015).Ecotourism no only protect the environment, it also admire the natural environment characteristics and respect the local culture. Ecotourism encourage visitorsto enjoythe natural environments with minimum impact and includes education to environmental conservation (Bob et al., 2008). Ecotourism means people travel to destinations…
