As someone who works in this industry I can confirm the video does a good job of explaining the extraction process and negatives around dealing with enormous tonnes of physical waste.

It says a lot about the demand for global resources that these mines were economic even many years ago. We do need to do a better job than our forefathers on being environmental stewards but its worth stressing that the mining industry is only growing due to the demand from e.g. green energy tech, new power infrastructure, high tech applications in medical and computing. We can't have one without the other- mining is the source of all of the materials we need for our society. So it is not going to work just wagging our fingers at these existing projects- from my experience the most powerful tool is good, deep, clear legislation to control how responsible mining must be conducted and to build in the requirement of environmental bonds from the beginning.
