In answer to your statement, the ministry does not
"...seek to exploit fear of the future in the same way that the Watchtower does."
- the climate crisis is already inducing that fear; the ministry assures people that there is a solution - even when we cannot handle the issue ourselves - and that it is not a Divine Slaughter as the watchtower prophesies. It also takes away the need to find the mythical "one-true-religion" or belief system in order to survive.
In short, this ministry is helpful and fear-removing, not exploitative.
