Very important and timely. It is desperately important that action to combat climate change is taken NOW. The last episode about humans certainly stressed this. My only criticism would be that I would have like a bit more in that final episode about how each of us humans need to look at our lifestyles, if necessary give up certain "un-ecological" habits, and what actions we can take to cut down our carbon footprints. So proud of David Attenborough for still putting out the message at the grand age of 94! My love to him
