Ever since the industrial revolution, air got significantly polluted by the industry. Air pollution is even more concentrated in cities that have an industrial zone. Especially in these zones, the presence of Sulfur-dioxide (SO2) and suspended Particles (PM) in the air is very high. Prolonged exposure to SO2 and PM can cause cancer, cardiovascular and respiratory disorders in humans. The aim of this paper was to a review available literature on air pollution by sulfur dioxide and suspended particles in the air region of Bor Copper complex, as well as to determine whether the investigated results are contradictory. Studies from prior years (2004-2015), as well as 2019, indicate rise of SO2 and PM air pollutants in the atmosphere in the region of the copper smelter of the Bor Complex in Serbia, which can cause serious consequences for human well-being. However, the results of research by different authors for the same years are not in agreement, with that said, a review of the literature indicates significant differences. In addition, no continuous research on any air pollutants has been done for several consecutive years. This can be an interesting question for the scientific public in Serbia. Review of available literature indicates that in Serbia, solving this problem must be taken more seriously.

Conventional agriculture is the greatest enemy of healthy soil; it wasn't designed for the betterment of the soil, but rather for the rapid economic growth. If we want to improve soil quality and with that our life quality, we should turn our fi eld of interest to the application of so-called conservation agriculture, which belongs to the principles of sustainable nature. Conservation agriculture is based upon three principles: minimum tillage and soil disturbance, permanent soil cover with crop residues and live mulches, and intercropping. Minimum tillage minimizes soil organic matter losses and leads to increase soil carbon and nitrogen stocks. One percent increase in organic matter can capture 10 times more tons of carbon dioxide. In this way, the release of carbon dioxide into the atmosphere is signifi cantly reduced. In addition, to maintain healthy soil system, there shouldn't be any bare soil left. Permanently covered soil leads to many advantages: Maintaining water capacity in soil which stops drying of soil (water is constantly being absorbed by crop), it reduces erosion and soil compaction, manages nutrients, controls weeds and increases yields. Additionally, intercropping is a way to create ecological balance, increase diversity in an agricultural ecosystem, increasing the quantity and quality of crops and reduce yield damage to pests, diseases and weeds. Conservation agriculture gives us the opportunity how to use natural resources more effi ciently with the minimal impact on the environment.

Solar heating and cooling, concentrating solar power and photovoltaic are three solar technologies which harness solar energy. Photovoltaic Technology (PV) is directly converting sunlight into electricity and it is very convenient to use. In addition, these devices are simple in design and easy to handle. The effi ciency of energy production this way is great. In order to obtain constant/continuous energy for consumption, the PV system can be a part of the so-called hybrid system. In the hybrid system, the PV system is combined with other renewable or non-renewable energy sources. However, there are certain problems in the use of solar energy, such as: cost, maintenance of the entire system and the impact of maintenance on the ecosystem, as well as the development of consumer awareness. Today, the world is forced to solve these problems in order to be able to save the planet from further deterioration of the ecosystem.
