There is increasing awareness that the quality of the natural environment in urban areas affects the social and economic viability of communities. The Key elements of the urban natural environment are trees in parks and yards and along streets and greenways. Collectively these trees make up the urban forest, which provides numerous benefits ranging from energy saving shade to attractive business districts. Urban forests are small pockets of green in a gray landscape. They are ribbons of life meandering through a largely artificial environment. They are enclaves of serenity and biological diversity tucked within the suburban development and busy streets. The worldwide trend toward urbanization threatens the ‘green infrastructure’ of our cities, Natural factors such as a region’s climate, soils, storm patterns, and the composition of presettlement vegetation influence current forest structure and shape perceptions of desired forest structure (McBride and Jacobs, 1986; Nowak, 1993). The physical development of cities influences the space available for vegetation and its distribution (Sanders 1984). Technological advances in areas such as transportation, air conditioning, and pest control influence attitudes regarding the value of trees, as well as their preservation and management (McPherson and Haip, 1989; McPherson and Luttinger, submitted). Historical data on the development of urban forests can be used with information on current forest structure to better understand key forces of change, current management needs, and future trends in forest health and productivity. As the notion of urban forestry broadens from street tree management to urban ecosystem management, a corresponding need exists for greater information about urban natural resources (McPherson, There are lack of appropriate tree planting spaces due to increased densities and more impervious surfaces. Pest, such as Emerald Ash Borer, and disease can have sudden and devastating effects, especially in areas that lack species diversity (NKUCFC, 2008). Approaches to the Problems Urban forestry is the practice of planning and managing landscape trees and green spaces. Many localities hire professional urban foresters to manage the public urban forest and help educate citizens about trees. But to have a healthy, sustainable urban forest, citizens have to pitch in to care for trees on private property too. The urban and community forestry program assists both localities and citizens in making science-based decisions about tree care and urban forest stewardship. Because urban and community forestry is multi-disciplinary, the program relies on partnerships and expertise throughout Extension and across the
These two sides of the issue bring about a major controversy in America today. Should the Pacific Northwest’s old growth forests and the welfare of the Northern Spotted Owl be sacrificed for America’s economy, and the jobs of the people in the logging industry? Which should be placed at a higher value, the forests in the Pacific Northwest and the northern spotted owl, or the American economy and the jobs and welfare of thousands and thousands of people?

Long-leaf pine areas have been converted to loblolly or slash pine plantations or severely fire suppressed. Urban development was a major cause of habitat loss in the early part of this century, as was logging.
When people see new construction or a recently paved road, they often do not realize the sacrifice that was made to create these luxuries. Most people pass some form of construction on the way to their jobs or school every day. This simple fact sparks questions regarding what this area looked like before it was inhabited by humans. Illinois forests have undergone drastic changes in the decades since European settlement. Only 31 % of the forest area present in 1820 exists today. (Iverson Pdf) Tearing down trees to build new structures isn’t bad if done in moderation, in some ways with time and good planning its wonderful. However, anyone that hunts or claims to be an outdoorsman will relate to the incomparable feeling experienced when alone in the woods and far from the hustle of the urbanized world.
Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.

Thesis: Forests provide the earth with a regulated climate, strong biodiversity, and good nutrient rich soil for plants to strive on.
An important feature of green roofs is their potential to provide habitation for urban wildlife, therefore many animal species such as rats and ants would benefit from green roofs. Coffman and Waites, (2008) explains that the urban development practices recognised as roof greening offers habitat for wild species within the towns and it also helps rise the home-grown natural diversity. However, roof greening is not a method restoration ecology, but it is method of reconciliation ecology, where entirely new habitation is formed for non-human species. In addition Green roofs certainly delivers some form of habitat, it is also possible that the properties of the roof could harm the wildlife diversity.
Again, this section will give a working definition of the “urban question’. To fully compare the political economy and ecological perspectives a description of the “urban question” allows the reader to better understand the divergent schools of thought. For Social Science scholars, from a variety of disciplines, the “urban question” asks how space and the urban or city are related (The City Reader, 2009). The perspective that guides the ecological and the social spatial-dialect schools of thought asks the “urban question” in separate distinct terminology. Respected scholars from the ecological mode of thinking, like Burgess, Wirth and others view society and space from the rationale that geographical scope determines society (The City Reader, 2009). The “urban question” that results from the ecological paradigm sees the relationship between the city (space) as influencing the behaviors of individuals or society in the city. On the other hand...
These motives are behind the current world’s 50% urbanization rate. Among all countries, Canada heads the urbanization process with 80% of its total area (Snell par.7). The ever-increasing urbanization rate is characterized by human-related destructive activities, which lead to creation of urban centers by destroying inherent biodiversity. The rate is increasing each passing day. However, one thing to note is that destructive activities embody the causes of urban biodiversity wicked problem. The easy way of identification provides land conversion, climate change, consumerism, land fragmentation, and invasive species as the main causes of the wicked problem of urban biodiversity. These causes constitute every aspect of urban life. For instance, there is no way that people living in urban areas can do without proper infrastructures (such as houses, roads, and communication lines). All kinds of infrastructure need space, and, in creating it, there is clearance of all natural vegetation and conversion of land to other uses. The result is annihilation of nature and predisposition of climatic changes. The only easy approach to identify an appropriate solution to the wicked problem of urban biodiversity is to decrease the rate of urbanization by
With more needs for nature experience and sustainable development in urban areas, increasing importance has been attached to urban open spaces since they play a crucial role to support the ecology system and form a natural network in the cities (Chiesura, 2004; Tzoulas et al., 2007). Urban open spaces include plazas, parks, campus, greenways and other green spaces. They serve as islands of nature, enriching urban landscapes, adjusting the microclimate, promoting biodiversity and providing habitats for other species (Chiesura, 2004; Do, Kim, Kim, & Joo, 2014; Morimoto, 2011). Apart from these benefits, they also show a great impact on urban dwellers’ health, since open spaces offer places for outdoor activities and opportunities for contact with nature (Chiesura, 2004). Tyrväinen et al. (2014) indicated that even short-term visits to urban green spaces have positive psychological and physiological effects on perceived stress relief. People were attracted to urban open spaces for physical activities, social interactions, and a relief from daily life, which benefit their mental and physical health (Thwaites, Helleur, & Simkins, 2005). A large epidemiological study in Britain looked at mortality and morbidity among three income levels in relation to urban residents’ access to green open space (Mitchell & Popham,
In this regard, city authorities all over the world are increasingly adopting energy efficiency measures in a quest to become sustainable into the future. Consequently, this has led to the emergence of the term ‘green cities’ (Aulisi & Hanson, 2004). New York City, viewed by many as an urban, concrete jungle, was recently named the “greenest city" in the United States. This is mainly because most of its residents live in energy-efficient buildings, and use public transport, bicycl...

No one can deny the basic human need for housing. And no one can deny that any advanced culture requires a great deal of paper to transact its daily business. However, one must also recognize the importance of forests in and of themselves. We must fight against deforestation and international community must also introduce stricter policies to stop deforestation. 1) First, we will talk about the effects of deforestation and why it's a problem. 2) Second, we will learn about the many causes of deforestation. 3) Lastly, we will cover how to solve this problem.
The world today is vastly different from what it was before urbanisation and industrialisation had taken its toll on the world. Since the turn of the new millennium the issue of the environment has suddenly evolved into a widespread issue which is greatly discussed throughout the world. No longer are humans living in a world where the environment is serene or stable but much rather becoming unrecognisable and diminishing before our eyes. The plants, trees and flowers are life forms which God has created for us to enjoy its beauty but it is now solely up to us and many other organisations to protect preserve and respect how fragile our environment really is.
