> spent a century producing literal mountains of plastic Plastic production is growing at 3.5% annually. This implies a doubling of annual plastic production about every 20 years (because 1.035^20 ≈ 2). And because of how exponential functions work, this also means there has been about a doubling of the total amount of plastic in the world over the last 20 years. So most of the problem has been created in the recent past. And it will get twice as bad in the next 20 years.
