The main problem of organizing the fight against global warming is that no one wants to bear high costs for the implementation of the proposed methods and technologies. It is already obvious that the owners of corporations and politicians from different countries will not agree among themselves. This means that an alternative is needed, and more and more scientists are inclined to simply restore what we have massively taken from the planet over the past half century - huge forests.
The forest is a magnificent, evolutionary mechanism for absorbing carbon dioxide and producing oxygen. A typical tree can store and hold more than 20 kg of gas per year, competing with the best industrial filters. It almost does not need maintenance, in addition, it has the ability to grow and fill new spaces with seedlings. It is estimated that if we simply re-plant logging sites all over the planet, it will cost only 2.5% of the money that they now want to spend on reducing emissions into the atmosphere. And all these trees will take away 37% of the total carbon dioxide of the atmosphere at once - no one can offer anything more efficient.
But it is necessary to plant forests, more precisely, to fight against deforestation of lands, for a number of other reasons. For example, hunger and jobs - in the Peten region of Guatemala, local communities have been given the right to fully control the exploitation of forests in the designated area. Their deforestation rate is 0, with 12% per year in the buffer zones between the jungle and farms, and at 20% per year for the country as a whole. Using forest resources, the community members not only feed, but also earn money to open schools and hospitals for themselves, which the state could not give them for decades.
Today, forests are cut down in the interests of big business, which uses large-scale and crude schemes for making money. However, it is possible and necessary to return to the practice of rational private land use, planting fruit trees, breaking vineyards, collecting nuts and honey. Along the way, planting at least one tree instead of one felled - all together will give an economic effect many times higher than from the barbaric plundering of lands. Plus millions of jobs, more affordable food and lower levels of carbon dioxide in the atmosphere.
These ideas have a concrete embodiment, the "The Bonn Challenge" project, in which the authorities of 56 states have pledged to re-plant 150 million hectares of felling areas by 2020. Everyone has freedom of choice, for example, in Ghana and Côte d'Ivoire, instead of forests, cocoa plantations will be created, which will form a sustainable export item and overcome poverty.
