The organization I work for, Rainforest Alliance put together this (very amusing) video to explain that you don't need to go to the ends of the earth to protect the planet - you can start by "following the frog." By purchasing goods like coffee, tea, chocolate, and juice with the Rainforest Alliance frog seal, you can rest assured that your dollars are supporting farmers who are earning a good wage and growing responsibly in a way that protects the environment and wildlife.
And you can know that your purchasing decisions are contributing to a transformative impact. For example, in just a few years, the Rainforest Alliance has trained over half a million small holder tea farmers to adopt sustainable practices and has certified nearly 10% of the world's tea. So you see, the decisions we make every day about what to buy - whether you look for organic or local or Rainforest Alliance or Fair Trade or FSC or some other sustainable label - can make a difference around the world.
Chop the watermelon into large chunks, removing the rind and any large seeds. Blend it with the mint and lime juice until smooth. You could strain it if you want to be extra classy, but it's not necessary. At this point, you can choose to store it in the fridge for a few days or the freezer for a few weeks. When you're ready to serve, mix the punch with seltzer, which thins it out and brightens it up. You want about 1 part seltzer to 1-2 parts watermelon. Add a shot of vodka or gin to each glass for a nice cocktail.
