2002. ‘Wetlands’]. Wetland plants oppose the erosive forces of moving water along lakes and rivers thus reducing the amount of sediment deposited into the ocean. Methodology: Research will be conducted on the benefits of plants in wetlands and the consequences of removing plants from wetlands. Step One: Set out small scale testing structure; container A and container B Step Two: Place plant (Calendula officinalis / marigold) in container A and leave container B empty Step Three: Pour 250mƖ of water into each container (using a beaker) Step Four: Measure the amount of water visible in each container (using ruler) Step Five: Observe and record the results *experiment to be repeated over a four week period* Results A table showing the amount of water(mm) in container A (with plant) and container B (without plant) from soil line Day Container A Container
While green technologies are not sufficiently proven, (Barnes, 2012). The new technologies that are implemented, they results in a great investment in a long-term by reducing maintenance and operation cost. Green buildings are built for a long-term use, and they are environmental friendly and built for economic benefit. Buildings plays a major role in harming the environment with pollution, therefore green buildings reduces this negative impact. (Angrisano, 2012 page 25) also supported green buildings, “As early as 1993, in an extensive evaluation of companies is UK and Europe, Hodgkinson (1993) notes that businesses increasingly want their flagship buildings to present an image of environmental friendliness in terms of energy efficiency, the use of building materials, and the impact on the wider environment.” Companies can also have a good relationship with the environment by constructing efficient buildings that are environmental friendly.
Factors Affecting Macroinvertebrate Diversity and Occurrence There are ecological factors regulating the distribution of macroinvertebrates (Hussain, Q.A). Water current, temperature, substrate, drainage basin land use/land cover, vegetation, pH of water, drought, flood, food, shade and stream geomorphology. Water current shows difference among aquatic animals according to its characteristics, either flowing water or a still water (Hussein). According to Steinnman, anatomical features of aquatic animals are influenced from their habitat due to adaptation (Hussein). Temperature is also an important ecological factor.
By utilizing processes such as clear-cutting and deforestation, living organisms that depend on these trees branches and roots have to migrate or die, other effects on climate, soil and water are also influenced (Cole and Nguyen, 2009). 3. The importance of biodiversity Plant richness is highest in areas of high productivity where moisture and thermal conditions are favorable for plant growth and are environmentally heterogeneous in South Africa (Richardson, Rouget, Ralston, Cowling, Van Rensburg and Thuiller, 2005). The areas with most plant diversity also included the most alien species. Alien species were found to spawn most in areas with high human activity (Richardson, et al.
So altering the natural flow pattern by damming, diverting or channelling water takes a serious toll on the plants and animals that depend on it. Since our water bodies are under constant threat from various anthropogenic pressures, environmental flow concept if applied can help us to replenish these dying water systems including our Lakes and can help us to restore and rejuvenate these pristine natural resources. Moreover, it can also help us to mitigate flood threats. It can aid us in tapping the potential of our plentiful natural resources. There is a popular saying "a drop that flows out to sea is a drop
Secondly, biodiversity plays an important role in ecosystem processes providing the regulating, cultural and supporting services. For instance, vegetation cover protects the soil from erosion by binding soil particles and minimizing the effects of water run off and also replenishes its nutrients . Likewise, cultivation of crops is impossible in the absence of the insects that aid in pollination. We the humans are so dependent upon biodiversity for our cultural, economic, and environmental well-being that it is beyond words to describe the importance it holds for us ,it is the basis of our existence and the very reason for our well- being. It is impossible to describe how deeply
My special interest is in green spaces and green cities and their effect on health. Especially how green can lead to both a process of gentrification or equality in quality of life. I am currently involved in a project at the Epidemiology Department of Erasmus MC, looking into the effect of quality of life and health outcomes and the inequalities per socioeconomic status and demographic characteristics, such as
Based on his investigations Lynch divided the contents of the city images into paths, edges (boundaries), regions, nodes, and landmarks. Weisman (1981) identified four classes of environmental variables that influence wayfinding performance within built environments: (I) visual access, (2) the degree of architectural differentiation, (3) the use of signs and room numbers to provide identification or directional information, and (4) plan configuration.. Garling et aL (1986) proposed to classify the environment by examining the degree of differentiation, the degree of visual access, and the complexity of spatial layout. Cornell et aL (1994) tested people s accuracy of place recognition and used the results to develop a model of wayfinding. 2.1. WAYFINDING IN THEME PARKS Visitors' movement become an issue in leisure park but how they can reach their destination at ease without being confused or worried about being losing track.
From this perspective, we can agree that a community of environmentalists would be a good idea for distributing help to different countries for habitat help. Helping countries to protect their natural habitats is for the better, because the habitats can be preserved longer. Though I understand that nature is changing 24/7, I still maintain that helping the different habitats is better. Although some people might object that countries should not help other countries preserve their habitats, I would reply that countries always help each other. The issue is important because we need to help reserve the different habitats all over the world for future generations, and many poorer countries live off their land to survive.
Reducing water use and protecting the quality of water are one of the main benefits of a green building. The protection and wise use of water in green buildings is accomplished by designing a dual pumping that recycles toilet water when flushing or using water for washing your car instead of it going down the drain. Water may also be saved by using half flush and full flush toilets as well as low flush toilet heads within the washrooms of the building. Bidets help eliminate the use of toilet paper as well as reducing sewer traffic and increasing the possibility of reusing water on site. The materials also have to be environmental efficent.
