Interest in protecting biodiversity is a relatively recent movement that coincided with the onset of global warming. true or false
I would say that this is true, although there is no absolute answer to this question and one could also find arguments against it.
But, we could set the beginning of global warming to 1940s -that's when the average temperatures started rising. Also 1940s is when the International Union for the Conservation of Nature and Natural Resources was founded - so it's around the same time!
