How should we respond to a problem that seems unsolvable? This is the question we ask in a series about the environmental crisis as we explore the fine line between hope and despair. After having delved into the hard reality of the environmental crisis for the previous two episodes, we spend this episode with our focus on hope. We explore what exactly hope is, how it relates to optimism, and how, when we find hope, we might also find repentance, forgiveness, joy, and love.
