A while back, I somehow came across a search engine that helped out the planet. For example, if you typed in GLOBR in the search bar, that search would go toward planting a tree somewhere in the world.
Even though it takes an average of 45 searches to plant a tree, the engine called Ecosia is a brilliant idea. If you think about it, if this engine becomes a large enough business, there could be thousands of more trees planted in the world all because of this searching.
I personally believe that people like you can make ideas shine in the world. If you have a good idea like this, and truly believe in it, then go for it and see what happens!
