Can peeling this bark help the environment?

Although China's economy is growing rapidly and great achievements have been made in various fields, the contradiction between the two has become increasingly acute. This situation is directly related to the irrational economic structure and growth pattern. Without faster economic restructuring and transformation of the growth model, resources will not be able to sustain, the environment will not be able to accommodate, society will not be able to afford, and economic development will not be sustainable. Only by pursuing economical, clean and safe development can we achieve sound and rapid economic development. At the same time, greenhouse gas emissions cause global warming, which is widely concerned by the international community. Further strengthening energy conservation and emission reduction is also an urgent need to address global climate change.

And cork is a kind of nature and the product that economy can develop jointly.

According to the world wildlife fund, oak cork has been the environmental, social and economic backbone of southern Europe and northern Africa for hundreds of years and has had a significant impact on more than 100,000 people living in the region. They live directly and indirectly on cork. Extensive agriculture, forestry, animal husbandry, hunting and economic activities related to cork and wine industries are examples of sustainable development.

About 340,000 tonnes of cork can be harvested from 2.3 million hectares of cork forests around the world each year, some of which is used to produce cork, with a total production of 12 billion. In Portugal, cork industry is acting especially important effect. Portugal accounts for 55% of the world's cork production, exports about 90% of processed raw materials. The most representative cork represents 70% of the total export value.

Important contribution of cork products

Cork products promote the protection and sustainable development of quercus variabilis forest. Quercus variabilis forest is very adapted to the warm climate and dry soil, which can prevent soil erosion and desertification. Cork, as the epidermis of cork oak, can be a natural barrier to fire. Its roots trap rainwater and become important watersheds, which then draw nutrients from deep underground and return to the soil through its leaves as a natural fertilizer. It allows tens of thousands of people to continue to live and work in arid or semi-arid areas. More than half the cork harvested is used to make different types of stoppers, and the rest is used for other purposes. Cork, therefore, has an important responsibility: to maintain an important economic activity and help develop cork oak forests.

Cork is used to allow cork forests to continue to flourish because harvesting the bark regularly allows the bark to regenerate itself. By regenerating itself, cork oak also reinforces another striking feature: its ability to absorb carbon dioxide. Quercus variabilis with a stripped epidermis absorbs an average of five times as much CO2. It is estimated that quercus variabilis absorbs up to 14 million tons of CO2 per year, making a significant contribution to reducing greenhouse gas emissions.
