In the 1970s or '80s, then we are accustomed to looking far ahead, say the year 2009, we have to imagine the world as a place where everything is "futuristic".
We would imagine that cars can fly, everything is driven by solar power, no more pollution, there is already a cure for cancer or the common cold, the streets are clean, can be a vacation to the moon or other planets far away, robots will be doing our homework and work in the garden, and so on and so forth.
We are accustomed to view it as an era in which rapid advances in technology in many fields such as medicine, agriculture, transportation, energy production, and the production of electronic tools for productivity or entertainment will solve many world problems. People will live longer and comfortable.
Why do we have to also see changes like that at least in the things we never imagined?
Year 2000 has been almost 10 years we've been through and even though we have made many advances, the world it is still more like 30 years ago than usual as the next state we previously imagined.
For example, a car has become increasingly streamlined, aerodynamic, and offers many advantages, but a car is still just a lump of metal and plastic on four rubber wheels that should we drive alone and that must be filled with fuel.
This is the same case with the movement to protect our planet and to become more environmentally friendly. For example, the sanctions have been established in factories that use fossil fuels to reduce air pollution, and the automotive industry must now designing cars that emit carbon dioxide and carbon monoxide to a minimum.
Although these changes seem good on the surface, when we really look at the broader situation, we will see that the cars and factories still make pollution - only slightly reduced. Just as smokers who think they can avoid cancer or other health problems associated with cigarette smoking by replacing them with low levels of tar and nicotine. They're just delaying something that can not be circumvented.
Why, in 2009 we have also seen a movement that led to the elimination of greenhouse gases, and instead just reduce their number?
Many of the major polluters are already taking steps that they need to reduce pollution levels that have their causes, but are now approaching 2010, and so far, no visible indication that they will stop the pollution unless they are forced.
American residents can be proud for having pioneered many positive efforts. Unfortunately, there are many efforts that are not too positive. For example, the U.S. is the world leader in terms of contribution to the greenhouse effect. Since the technology is more than 50 years, the U.S. has created a car with electric power, solar power, or some other fuel that can be updated and a cleaner, then why in 2009 there were still factory that produces cars that require combustion of gasoline?
With many changes taking place, much remains the same. I ask this rhetorical question in the hope that more people will start questioning the same thing.
The problem is, these questions have been asked to the people who have power and who can make meaningful changes. Long conversation and heated debate has occurred, the study of environmental impact has also been implemented, and meetings have been held. In the end, seems the most important decision factor is always money. Why? (A. Darin / The Epoch Times / mer)

THE IMPORTANCE OF ENVIRONMENTAL GREENINGGreening is one of important activities that should be implemented in conceptual in addressing the environmental crisis.
Many facts show that no development is rarely built on open green land. While plants in the ecosystem role as the first manufacturer to convert solar energy into potential energy for other creatures and turn CO2 into O2 in the process of photosynthesis. Therefore, by increasing greenery in urban areas means to reduce CO2 or other pollutants that contribute the greenhouse effect or climate disruption. In addition to the vegetation plays in the lives and health of the physical environment, also play an aesthetic and spiritual and physical health. Given the important role of this vegetation, especially in urban areas to address the environmental crisis will require awareness, planning and implementation in an effort to green the environment. From the various observations and research there is a tendency that the implementation of greening is not conceptual, in fact so impressed origin. Selecting plant species for reasons easily available, cheap and fast growing.
Greening
Greening in the broad sense is any power to restore, maintain and enhance the natural conditions in order to continue production and to function optimally, both as a regulator of the water system or a protective environment. There are also saying that the greening urban areas is an attempt to green the city by carrying out the management of city parks, neighborhood parks, green belt and so on. In this case, urban greening is an activity of filling the open space in urban areas. In the process of photosynthesis of green plants take CO2 and release O2 C6H12O6 and the role of much-needed human. Therefore, the role of green plants are needed to capture the CO2 and release O2 back into the air. In addition, various metabolic processes of green plants to provide various functions to the needs of living things that can improve environmental quality.
Once the importance of the role of plants on this earth in addressing the environmental crisis, especially in urban areas, is very appropriate if the existence of plants received serious attention in the implementation of urban greening as an element of the urban forest.
Greening role and function
* As the lungs of the city. Plants as green element, the growth yield of acid (O2) that is necessary for living things to respiration;
* As the regulatory environment (micro), the vegetation will cause local environmental air into cool, comfortable and fresh;
* Creator of the environment (ecological);
* Balancing nature (adaphis) is the establishment of places of natural life for the animals that live in the vicinity;
* Protection (protective), the physical condition of the natural surroundings (high winds, hot sun, gases or dust);
* The beauty (aesthetics);
* Health (Hygiene), (Recreation and education (educational);
* Socio economic political.
Selection of plants for greening in order to grow properly should be considered the terms of horticulture (ecological) and physical conditions. Horticultural Terms of responses and tolerance to temperature, water requirements, nutrient requirements and tolerance to sun exposure, soil needs, pests and diseases, as well as other physical conditions of greening purposes, cultivation requirements, canopy shape, color, aroma.
Elements of the urban forest (urban forestry)
Functions and benefits of forests, among others, to deliver results, pencagaran flora and fauna, ground water and erosion control, climate amelioration. If forests are located in the city functions and benefits of forests, among others, creating a microclimate, architectural, aesthetic, modification of temperature, seepage of rain, wind and air protection, air pollution control, waste management and minimize the reflection of sunlight, soil erosion control, reducing surface flow, soil binding. Construction of vegetation may regulate water balance by way of interception, infiltration, evaporation and transpiration.
Review the functions of urban afforestation and forest functions can be said that urban greening is an element of the urban forest. While the urban forest is a part of urban green open space. Forest city (urban forestry) by Grey and Denehe (1978), includes all woody vegetation in an urban environment, ranging from small villages to large cities. Fukuara et al. (198 argued about the urban forest, the open space is overgrown with woody vegetation in urban areas that provide maximum environmental benefit to residents of the city in the usefulness of protection, aesthetics and recreation and other special.
Meanwhile, according to Grey and Denehe (1978), forest city (urban forestry) include all woody vegetation in an urban environment, ranging from small villages to large cities. Given the nature of forestry yard contains aspires to the interests of the people, then that is grounds forestry development seems to be more democratic is the people-managed agroforestry systems. The yard can produce wood, bamboo, carbohydrates, proteins, fats, vitamins and medicines.
As a consequence of plants as the first manufacturer in the ecosystem, and considering the functions of the urban forest and urban greening function relies heavily on vegetation that is used then no longer disputed area of land as a condition of the urban forest. What matters is the number and diversity of vegetation in urban garden as much as possible. Thus, urban greening as an element of the urban forest needs to be improved conceptually includes planning, implementation and maintenance by considering the aesthetic aspects, environmental preservation and functional. Implementation shall be in accordance with the planning as well as maintenance must be done continuously.
Planting techniques
Major factors to note are the tree-planting technique is,
* Selection of plant seeds. Generative seeds are derived from seeds, a seed that is more appropriate because it has roots upside and can live longer. Vegetative seedlings, are the seeds derived from vegetative parts of plants, such as stems, leaves and roots. Vegetative seedlings are generally less robust and shallow roots, so quickly destroy sidewalks, streets or drainage channels. Good seed has grown at least in the container for 6 months with a minimum height bar + 1:50 m and 0:05 m in diameter, to test it enough to pull out the seeds. If the seedlings easily separated from the container means new and has not moved quite well planted on the ground, on the contrary, if difficult to remove means roots is well established and can be planted in the field
* Planting. Keep the soil before planting digemburkan first. Size of planting hole is very dependent on the size of plant
* Nursing pascatanam. Maintaining a position to grow in order to remain upright and stable. Watering the plants once every 2-3 days, especially in the dry season while throwing twigs that kerimg. If you need 3 months to cultivate plants with NPK fertilizer.
Other forest benefits are:
* As suplyer Oxygen which is the main raw material for human respiratory
* For flood prevention
* As a natural conditioning
* As the world's lungs* There are many more benefits for other human forest.
