Natural World Into Extra Time?

The UN Wildlife Chief appears to be pessimistic about our chances of saving the natural world  by reducing the current obsessions of the 'adults' (our politicians and industrialists) with deforestation, over-fishing and over-exploitation (https://www.theguardian.com/environment/2019/jun/24/survival-of-natural-world-is-in-balance-says-wildlife-chief), all in the interest of supposed economic development, jobs and food. She seems to feel that mass extinctions of animals and plants is likely to continue, along with the effective destruction of the planet's ecosystems (particular species are like cogs in a complex mechanism). Her view that the 'young' are clearly apposed to these destructive trends appears to provide a chink of optimism but one has to ask whether this will amount to 'too little, too late'.
