I have read the applicable laws quite thoroughly. In Poland they called it the "Act on the prevention of agro-phages". Who works longer feels what's going on. They hid the general restrictions under the guise of fighting imaginary threats, and most "stuck" all activity on the Internet.
The most painful changes concern online stores. Currently, every plant sold via the Internet (distance contract) must have a passport. It doesn't matter if you are a professional seller or an amateur who has arranged through the forum to exchange plants with a friend elsewhere. You must (on pain of a penalty) attach a passport. Passporting applies to shipments within the EU. For shipments outside Europe, they arrive outside of passporting - the requirements of the specific country to which the shipment is directed. For example, an agreement with the USDA must be attached to the USA, when sent to Japan, it will be a phytosanitary certificate, etc.
Be glad that you can still send plants with restrictions, but you can. In a while, they may even prohibit all plants shipments. The lobby of large producers is on hand to make producers cease to exist. As usual, it's about money and not about any protection. Pests know no borders and do not read permits. All virulent organisms move despite restrictions imposed by humans.
In my country, one wise man said this: now ecologicalism has become a new, dangerous religion which is trying to replace the existing foundation on which Europe (Christianity) was built. Due to such activities, man is as if in second place - ecology is more important. People are trying to impose certain solutions, thinking of the fact that they will avoid the problems of cyclical climate change or natural pest moving. Unfortunately, they are nonsense. We are abducted by the ubiquitous bureaucracy which is getting bigger like a snowball.
Who works longer in this profession knows that almost every plant from the market is wearing pests (those that have survived repeated chemization and will show what they can in month or one yer, but will be). It is similar in amateur crops. Pests are a natural and inseparable part of plants (when I write pests, I mean insects that humans consider unnecessary or harmful). How will the situation change after December 14, 2019 in Europe?
Until now, plants with pests were sent without documents, and for free (or only with the name of the plant and documents certifying payment of taxes). Now plants with pests will be sent with tax documents, additional "plant passports" and we will pay extra for it.
The worst part is that the governments is trying to draw new taxes, fees for their ideas from all sides, and few societies express their dissatisfaction. An example would be yellow vests in France. There probably still people have "eggs".
However, this is not enough. With every such stupid change limiting our freedoms, there should be hundreds of thousands or millions of people on the streets of Budapest, Warsaw, Prague or Berlin (in Paris already). Then the rulers, introducing any restrictions or a new tax a thousand times would wonder if it serves people or can it be introduced etc. For now, we have a warning in the form of Brexit that EU policy is one big socialist (sorry for the expression) guano.
Thanks for the time spent reading
