In many countries, in individual regions and urban agglomerations, tree planting projects are currently underway as part of afforestation programs for civilization-modified areas. In some countries afforestation of civilizational modified areas is considered one of the most important instruments to neutralize the negative effects of greenhouse gas emissions. The main premise of this thesis is the fact that certain species of trees and shrubs absorb significant amounts of CO2 and improve microclimate and water management in surface layers of soil. However, according to the results of scientific research in a situation of high greenhouse gas emissions, afforestation will not solve the problem of global warming. If in a given country, in a given agglomeration the majority of households, motor vehicles and enterprises from the energy sector relies on burning of minerals, the emission of greenhouse gases is so high that afforestation may reduce this emission to a very small extent. In this situation, apart from afforestation, other projects should be developed that will enable the implementation of the principles of sustainable, pro-ecological development based on the concept of a new, green economy. These other pro-ecological undertakings include, first of all, the development of renewable energy sources, increasing the efficiency of waste segregation, recovering secondary materials, development of electromobility in the automotive industry, development of programs for implementation, implementation and financing of eco-innovations, such as the construction of small household ecological power plants based eg on installing house roofs photovoltaic panels replacing stoves, in which often poor quality minerals are burned, etc. Therefore, afforestation does not solve the serious problem of global warming but should be developed as one of many instruments to reduce the negative greenhouse gas emission effects.
In addition, it is particularly important to protect existing forest resources, including natural forest ecosystems characterized by high biodiversity, and therefore a high biological value, such as rainforest, tropic rainforest of the Amazon. However, this is only an example of the largest, existing natural forest ecosystem on Earth. All other such ecosystems should be under strict protection and should be excluded from the predatory, devastating forest exploitation economy, i.e. harvesting timber from these natural forest ecosystems, because in the context of the problem of global warming they are one of the most important, most valuable resources of the planet Earth.
In view of the above, the current question is: Can the afforestation of civilization-modified areas significantly reduce greenhouse gas emissions?
