Humans have faced urgent crises over the past two years, and in the midst of those we still have the threat of climate change and other big, systemic problems facing our world. In this time of chaos and crisis, how do activists find the strength to carry on? In answer to this question, environmental philosopher Kathleen Dean Moore has assembled a collection of short essays that offer courage, hope, and even some laughter to the people who have for years been working for environmental sanity and social justice. Earth's weary lovers, as Moore calls them, are tired, perplexed, and battered from all directions. Their hearts have so often been broken; it's hard to go on, but it is morally impossible to quit. To these weary activists, Moore brings encouragement to join or keep on with the struggle-not entertaining distractions, but deep and honest reasons to remember that the struggle matters, now and in the future. Moore's essays are matched with drawings by Canadian artist Bob Haverluck; together, they invite readers to take heart. Taking heart is not hope exactly, but maybe it's courage. Not reassurance, but reason to persevere. Not the promise of good results-it does not depend on winning odds-but a call to integrity. Not strength, but stubbornness, which might be just as good. Not solutions to the planetary crisis, but some modest advice for the inevitable crisis of the heart. Not good cheer entirely, but a chance to grin, and gladness to be part of this strange and necessary work for the endangered Earth.
