In your opinion, what is the most pressing issue facing humanity today, and what role do you see yourself playing in addressing it?

What we humans are doing to our planet - we are slowly killing our environment and it's going to bite us in the sit-down. The most obvious is polluting the air we breathe and the water we depend upon, releasing harmful chemicals into the atmosphere, and plastics in the ecosystem.

And yes, climate change is real, both the natural changes that have occurred over millennia and what we humans do to accelerate change.
