Another study of park improvements found increased number of white users, but no significant change for black, Hispanic or other park users. Although these two studies provide a limited basis from which to draw inferences, the possibility that infrastructure improvements may predominantly benefit socioeconomically advantaged groups warrants further exploration in future evaluations.
As identified in previous reviews, there was substantial variability in the methodology, measures, and analytical processes used to evaluate the impact of environmental interventions. Overall, this made comparisons between studies and intervention delivery approaches difficult.
In part, this variability may be a by-product of the significant differences in intervention typologies and associated research designs. There remains, however, a need for improved study quality, which may mitigate this somewhat e. Our quality assessment rated three-quarters of included studies as weak.
Studies were frequently limited by lack of representativeness and generalisability. In most cases, blinding was not described in studies. It is worth noting there are ethical issues to be considered with participant blinding such as informed consent , and that these can sometimes conflict with quality assessment criteria, where blinding is desirable to reduce bias associated with participant self-report or reactivity [ 67 ].
We chose to retain this category for consistency with the EPHPP and previous research that has used this tool. An indepth consideration of the issues surrounding the evaluation of blinding in quality assessment is beyond the scope of this review, but should be taken into account in future reviews in this field. Few studies comprehensively controlled for confounders.
While sex and age were commonly controlled or stratified for in analyses, only some included robust measures of SES or ethnicity. Depending on study design, area-level SES and ethnicity characteristics may suffice in order to mitigate challenges around collecting these data at the individual level. In their systematic review, Schule et al. Issues around contamination and consistency across intervention sites were rarely considered and were not controlled for in any analyses.
Future studies would also benefit from considering neighbourhood self-selection as a possible confounder. In their systematic review, McCormack et al. Likewise, baseline activity was rarely controlled for in analyses. One recent study to consider this factor revealed that existing cycling behaviour, as well as distance to the intervention site, was associated with increased use of a new bike path in Australian adults [ 68 ].
Overall, there was a lack of research specific to children or older adults. It is possible that the adult-centric approach to characterising built environments may not be sufficiently capturing environments that matter to younger populations.
For example, in their earlier review, Sugiyama et al. A recent systematic review showed that where youth physical activity was geo-located i. In keeping with Hunter et al. The lack of clear and consistent reporting of intervention cost limited any ability to determine whether a relationship existed between expenditure and behaviour change, and whether costs differed significantly between intervention types.
Moreover, the low quality of evidence found overall negatively impacts confidence in estimations of cost-effectiveness of built environment interventions [ 41 ]. Compared with infrastructural interventions, relocation studies are less hindered by infrastructural cost. RESIDE is perhaps the first study of its kind — a natural experiment involving longitudinal data collection with new residents of new housing developments [ 69 ]. The study commenced in prior to participants moving, with follow-up data collection occurring with participants approximately 12 months after their baseline pre-moving survey.
This important study demonstrates the value of well-designed residential relocation studies. The substantial inconsistency in timing and number of follow-up measures post exposure i. In their systematic review of natural or quasi-experiments, Mayne et al. This phenomenon was observed in the iConnect study, in which no effect on behaviour was observed one year after a major environmental intervention, but significant changes were found at the two-year follow-up [ 56 ].
Pragmatic and economic factors may limit the feasibility of repeated and longer-term follow-up periods in this research field, but where possible this should be encouraged. Finally, it is possible that publication bias affected the balance of studies included in this review.
In general, registration or public release in other forms of study protocols prior to the publication of findings provides a check on selective reporting of study results. This systematic review focused on physical activity behaviours and use or visitation of settings, and did not include more distal health measures such as body size [ 72 ]. While these outcomes are unquestionably important, this approach was taken recognising that: a a substantial period of time exists between sustained activity behaviours and manifestation of associated health outcomes, and b studies in this field rarely examine effects of the built environment on activity behaviours for a sufficient period of time to expect meaningful changes in health outcomes that are downstream from improved physical activity behaviours.
The broad inclusion criteria used here are a strength, drawing on studies across all quality assessment categories as well as considering findings in light of study quality. However, the exclusion of grey literature could have been a limiting factor, in that it is possible that significant new lines of inquiry might have been overlooked. While acknowledging the important role of perceptions on the relationship between the built environment and activity behaviours [ 73 , 74 ], this review focused only on objectively assessed built environment features.
The association between the built environment and activity varies, depending on whether perceived or objective measures are used [ 73 , 75 , 76 , 77 ]. Moreover these differences are not consistent, and vary along with individual factors such as education level, income, body size, and physical activity [ 74 , 78 ]. Individuals who are more physically active may be more familiar with their local environment, and more aware of both positive and negative features, than those who are less active [ 79 ].
In the interest of providing clear and direct information to inform policy and practice that was not complicated or hindered by individual perceptions, we chose to focus on objective measures of the environment. Future reviews may consider replicating the current study with a focus on perceived environmental features only, while others may undertake the task of considering both objective and subjectively-assessed environments.
There is an emerging body of research that simultaneously considers both objective and subjective measures of the environment in relation to physical activity [ 76 ]; offering challenges and opportunities for future reviews in this area.
Our focus was on being able to isolate the effect of specific built environment features or interventions, thus studies that employed aggregate measures e. A range of robust studies exist in the field that have utilized aggregate measures [ 80 , 81 ]. The exclusion of this research limits an understanding of the combination of features that encompass a pedestrian or cyclist friendly environment. However, this approach was taken in the interest of generating specific findings that could be translated into policy and practice.
Measures that combine variables may be difficult to interpret, if it is not possible to determine which components are most effective. Future reviews with differing aims could consider including aggregate scores, and might extend this to broader aggregate concepts such as obesogenic environments [ 82 ].
There have been calls for more systematic approaches in reviews in this field [ 83 ]. This study employed robust systematic procedures following best practice, and improved on existing reviews by conducting quality assessment of articles, considering article quality when summarising results, including literature for children and adults, excluding cross-sectional studies, and attempting to isolate the effect of the built environment from other interventions occurring in studies.
With the intent of providing evidence from the most robust evidence possible and undertaking a process that was as replicable as possible, as well as drawing from existing high quality reviews in this field [ 12 , 14 , 16 , 30 , 31 , 46 ], this review did not include grey literature or involve forwards citation searches.
Future reviews may undertake these processes to capture an evidence base that is as broad and up-to-date as possible [ 45 , 84 ]. Although our global quality assessment score does not include measures of study contamination, consistency, health equity, or intervention cost, these factors were systematically considered and presented in the context of understanding the overall quality of studies presented in this review.
The strongest evidence existed for multiple streetscape components adult PA, child AT , installation of fitness equipment adult PA and AT , temporary road closures and play equipment child PA , and recreation facility density adult PA.
Numerous limitations in the evidence base exist. In particular, the possibility that the benefits of infrastructure improvements may be inequitably distributed requires further investigation. Notwithstanding the significant challenges in terms of research design, many opportunities to improve the quality of evidence are clear, including strategies to improve response rates and representativeness, use of valid and reliable measurement tools, cost-benefit analyses, and adequate controlling for confounders.

The alternative forms of energy, termed green energy are renewable sources of energy e. Theses green sources of energy do not contribute to the deterioration of the environment. The industrial production of hydrogen gas H2 is dependent on heavy use of fossil fuel-generated electricity to power the process It consists of six countries in the Middle East. The main objective of the formation of this council is to achieve unity among the countries. Consequently, the success of this council is due to the fact that the member states share common cultural and political beliefs rooted in the Islamic faith they profess.
There are different sources of waste including residential, industrial, commercial, institutional, construction and demolition, municipal, agriculture and manufacturing and all these waste products whether solid, gaseous, liquid or radioactive come under the realm of waste management. Due to the rapid growth and fast development in Australia, the country has produced waste on humongous amount.
As per the data provided by Australian Bureau of Statistics, the growth of average annual rate of waste production in Australia is about 5. This one-act play has won the Pulitzer Prize for drama.

The values, beliefs and conventions in the society begin to take shape in the minds of the children. The kind of atmosphere This is due to the emphasis that has been made by various international environmental conservation organizations on the need for companies to provide a favorable working and living environmental for people in the world. The need for environmental friendly integrations is driven by the need to ensure that there are no further negative impacts that are made on the environment due to poor waste management and other wastes emitted from companies in production such as carbon monoxide emit ion and other poisonous gases Therefore, a straight statement can be declared about the annual average growth to be 1.

He does try to leave the article on a much lighter note at the end, ensure the readers that the earth, which is capable of rejuvenation, will fix itself. Logic One of the most obvious lacking rhetoric in the passage is that Rush Limbaugh uses no other credible source other than himself. Though, Atwood have produced many works, not any of her works has this much portrayal of nature and environmental issues as it is done in the novel Oryx and Crake.
Atwood believes that the climatic change is something that would cause a huge damage to the world as these climates do not change with the blessing of the Mother Nature but due to the horrid actions that is done by the humans. In the novel, Atwood in many places shows what would be the future like with the abomination of natural. They also point out that global warming consensus is not based on science, but for the political purpose. From my perspective, the severity of climate change indeed can affect the decisions of policy-makers, such as green policy and governance.
But it does not mean that people can just ignore the consequences of the enormous emission of greenhouse gases in the past few decades. Climate change is denied is due to the prioritization of business and the economy. Large corporations create their products with uncostly materials, in order to profit more, and those materials are more-often-than-not non-renewable resources or cause damage to the Earth.
These corporations prefer to not be targeted with accusations of the unethical damage they are causing. Therefore, they create propaganda against climate change, they create doubt among their customers. It is considered a business tactic to create news surrounding issues, in order to distract the consumers from whatever controversial issue that is, or could be, affecting their sales.
That over two decades there has not been any significant change in the way majority of people acknowledge that one of the major issue humans face is global warming. Even though relatively recently several countries did join the Paris climate agreement to confront climate change but it still does not help there is still a large amount of countries that will not contribute in reducing the effects of climate change.
It does feel hopeless at times trying to get people to at least acknowledge climate change and there is not be a chance to change the path of our future right now because it would be too late. Environmental issues began to be discussed and debated only towards the end of the 20th century. Since then significant amount of literature has been penned down raising awareness about issues of pollution, deforestation, animal rights and several others however it has failed to result in major changes, ideas or even actions to save the environment.
Several species of animals have become extinct; pollution level is at an all-time high, global warming is leading to severe climate changes all across the globe but these problems do not seem to alarm the decision makers. McKibben suggests there is inefficient spending and mechanisms by individual consumers. For example, a lots carbon emissions and sewage caused by individual consumers is the result of their inability to use the latest technology.
On the other hand Jensen argues by saying prejudicing powerless individuals instead of those who actually attain influential power in the system of government and policy making is one of the problems to mitigate environmental pollution. Many believed the Dust Bowl and floods of the Great Depression were natural disasters and framed destruction of the Great Plains as the result of weather, not human-created tragedies, even though scientific evidence proved otherwise.
However, when the news and government framed stories a consequence of weather conditions they failed to communicate the balance of nature was overturned thanks to the unbridled settling of the land that caused ecological disaster. The news presented only part of the story, devastation. Largely missing from reporting why ecological disaster came about, the connection between water and soil, and how unrestrained use and poor planning led to disaster. He believes that the concept of climate change was created by the Chinese to suppress the U.
What he sadly fails to see is that the plans he has to invest in infrastructure will ultimately corrode if implemented due to the fact that climate change ages and breaks down infrastructure. There are scientific reports that the flu death numbers are way too high.
