When it comes to the climate crisis, one action can spark a chain reaction. In this week’s Climate Justice newsletter, we look at the results of positive change. First, what does a court case in Peru have to do with Montana, and could this ruling set a precedent throughout Latin America? Next, universal school lunch programs can shorten supply chains and keep money in communities if they use local farms and gardens. Then, can philanthropy fill the gaps to help meet the short and long-term needs of rural communities of color? Finally, a new book offers guidelines on how to prepare, respond, and recover from an outbreak.
