Abstract
Planting trees is popular, widely accepted and supported, resulting with many initiatives and commitments around the globe. At the same time, planting trees is questioned more and more and receive a lot of criticism. In this paper we consider the arguments of both sides and discuss them using a scientific evidence. Determination of restoration opportunities and restoration needs requires more intention to existing ecosystems and their use. Commitments and expectations need to be realistic to maintain constant support based on real results. Planting trees is not the best solution for carbon storage, but it is one of the best solutions available at this moment. Even if reduce anthropogenic CO2 emission to zero, we will need to plant trees. Planting trees can have both negative and positive effect on water availability and socio-economy, depending on restoration practice applied. Planting trees is definitely good, if it is done at appropriate site and with appropriate tree species and if it is based on proper planning and realistic expectations.

Summary
In past decades most countries worldwide have suffered forest loss or degradation due to changes of land use. Reforestation, afforestation and restoration of forest landscapes can have a positive effects on functionality and productivity of degraded lands and forests, boost food production and resilience of agricultural landscapes, size up the supply of clean water, reduce erosion and provide wildlife habitat and mitigate climate change by sequestering carbon (Laestadius et al, 2011).Ambitious and large, sometimes gigantic initiatives and programs of forest restoration, forest landscape restoration, afforestation or simple tree planting has been launched worldwide in recent decades This raises many questions and produce doubts. This paper does not discuss different restoration approaches and definitions, but rather uses terms as they have been used in references used
