I'm old and this may not happen in my lifetime, but I fear the collapse of the ocean current systems. The resulting global weather chaos would have a drastic effect on my younger family members, some of whom are already struggling to make their way in the world.

The way governments everywhere are backing off green commitments and seems only interested in waging war and/or protecting the greedy makes me despair, but every single day I meet people with warm hearts and open minds, so I do have some hope.
