Abstract: The air becomes polluted when the concentration of newly introduced substances from human activities or from natural sources, systematically or accidentally, exceeds a certain level that generate toxicity for humans or for other living beings. This is one of the most often cited definition of air pollution. Beyond the dirtying effect suggested by this statement there are other effects too that come into action in certain conditions. 
The paper aims to uncover some of these effects by referring to the impact on the regulatory mechanism of the atmosphere and also the consequences in terms of changes in the living conditions. In fact process that undergo in the air lead to the elimination or neutralization for most of the pollutants. Nevertheless, than the path of emission exceeds the path of elimination, some pollutants mount up and generate the so called cumulative effects (IPCC, 2014). 
These cumulative effects enter into action at different spatial scales by various mechanisms. It could be differentiated global, regional, and local cumulative effects. This process is unleashed by changes in the composition of atmosphere. These changes mean increased concentration in carbon dioxide, nitrous oxide, methane, and freons. Our paper refers to the first category and uncover its mechanism, causes and consequences. 
Key words: air pollution, greenhouse gases, climate change, ozone depletion

Abstract: The sustainable development is a concept of great importance today, defined by several dimensions, such as referring to the fulfillment of human interests, the environment created aimed at matching the natural man, but by the social. The definition and its practical implementation must take into account more factors and the specific principles. From the economic perspective, economic policy must integrate the ecological principles that ensure its successful development to be sustainable in the long term. This paper presents the case of economic and ecological approach in territorial that is about developing the South-Muntenia Region of Romania. 
With a total surface of 34,453 km(14.54% of the total area of Romania), the South-Muntenia Region [3] consists of seven counties (Argeş, Călăraşi, Dâmboviţa, Giurgiu, Ialomiţa, Prahova and Teleorman). 
The relief of the Region 3 South-Muntenia is characterized by variety, the difference in level is over 2400m allocated in proportion, stepped down from north to south of the Făgăraş and Bucegi mountains and ridges to the Danube Valley, which leads to the types of mountain, hill and plain climate. Like all developing regions of our country, in the South-Muntenia Region also are made efforts to attain the sustainable development objectives. The situation of the region is studied through analysis of the economic indicators and environmental development. 
Key words: economic approach, ecological approach, sustainable development.

 Abstract: It is very important to communicate to the general public the multifunctional role of EU farmers which goes beyond food production. Farmers play an important role in conserving our common natural heritage and in many rural areas they continue to be the economic heartbeat. This must be done for the following purposes:
- the need to better respond to market opportunities;
- emphasizing that the reformed CAP has strengthened the EU farmers' ability to respond to market signals, thereby giving the EU an opportunity to strengthen its supply of food at a time of higher food prices and help to alleviate the concerns about food security in some parts of the World;
- the simplification and better targeting of the direct support to farmers;
- the strengthening of the rural development policy to respond to new challenges, mainly related to climate change, water management, renewable energy and biodiversity.
Key words: CAP – Common Agricultural Policies, CROSSCAP/2010 Italy-Romanian Project, rural,  renewable energy and biodiversity.

 Abstract: In an effort to help understand better the whole service area, arose the idea of this research on the content of the services and the analyze of resources, services in the contemporary economy, market demand and quality service. Research undertaken in this paper tried to highlight the role of services in the Romanian economy, based on the contribution approach from different angles and that of the degree of engagement of services in the global effort of economic development as follows: employment in service activities (which increased from 44.9 to 53.3%); contribution to GDP creation services, net investment in services and labor productivity over the other sectors of the economy (3 times higher than the primary and secondary sectors). 
The research had highlighted the slow development of these services in the analyzed period of 2007 – 2014. The countryside has great natural resources that can contribute to a greater extent in development. We are talking about forests (which represents 52.5% of the county) and 17 rivers arranged as hydro-electric stations for hydro-electric production. Rural transportation are fully private and no longer covered by municipalities. 
Based on conducted research there was drawn the SWOT analysis of County and of the commune, these analyzes highlighting the strengths that correlate with opportunities and weaknesses which in turn correlates with menace or risks. On the basis of this analysis were the statistical data processed to reveal the dynamics of services, their structure and effects on rural development, there have been used general indicators of services and specific indicators for each type of service as well. There were analyzed permanent services on water feed production, collecting and disposal of water, gas, electricity and sanitation.
Key words: resources, services economy, market, SWOT analysis.

Abstract: "Green energy" is a term that refers to renewable and unpolluted energy sources, implemented in the Ecological Complex Comorova Forest Neptun - Romania, owned by Bioterra University of Bucharest. Students perform their specialty practice stages here. So by choosing some renewable energy sources consumers can support the development of clean energy that will reduce environmental impact and increase energy independence. Bioterra University’s energy policy is based on the existence EU 2020 Biodiversity Strategy which states "objective 20/20/20":
- reduce greenhouse gas emissions by 20%;
- the use of green energy at a rate of 20 %;
- increase energy efficiency by 20%. 
So, within the Faculty of Environmental and Costumer Protection was started a research project which has the aim is to achieve full energy independence within Comorova Ecotourism Complex. 
Major investments have been made from our funds, in order to achieve the objective mention before, by purchasing wind turbines, solar panel kits, solar panels for hot water preparation, heat pumps, infrared panels, led bulbs and green mobility. The study of weather phenomena, monitoring and processing of electrical parameters was carried out in real time with modern equipment assisted by computer and with Internet connection.
Key words: green energy, energy independence, ecological, computer, environment.
