Either the government should set up firms to mine amber, or it should allow the miners to mine the resource without harming the environment. But they are not doing either of these measures. There is no enforcement of any kind.
Amber brings a very big money to corrupt politicians. There is a public firm that needs to produce amber, but she is in year produces less than underground miners mined a day. These corrupt is not profitable to legalize production.
Yes, legalization of amber mining does not make sense. It will be too expensive and unprofitable.
