Who has not ever played with Lego blocks and had enormous fun? Well, that world of Lego is existentially threatened by the increasing on-the-noseness of continued oil use among the aware in our society, not to mention the imminent demise of the oil industry itself.
The Lego company is also well aware of this threat to its continuity and is seeking to do something about it. They have indicated (having probably been shamed into doing so) that their special relationship with Shell Oil will not be renewed on its expiry.
Plastic, as I am sure that you already know, is produced from refined oil products and all such manufactured objects will soon need to be replaced by some other material. Plastic is so ubiquitously prevalent in our modern world (can you think of all the other plastic objects that you daily rely on?) and I am fairly certain that there will be no material found that can replace it (just as there is no replacement for oil itself). At least no material that will be acceptable for large scale industrial production across all sectors of modern society in an oil deprived world that is struggling to cope with an increasingly dangerous and disruptive climate
…and plastics are only one of many uses in which we have rather foolishly placed our reliance on the limited and rapidly dwindling supplies of oil that are available to us (or that we can, for our own safety, keep extracting).
What is to become of the cosy industrial world that we have for such a short time enjoyed and played for all it was worth, while it lasted?
