Unfortunately, do good doesn't mean funding. Your goal is to seek a profit making model. Or at least one that seems like it can make a buck over the long run. Option one seems easy to understand so it should be easier to fund. It might be pitched as growing food in the desert. Find what fruit/seed can be grown so that the trees stay alive and they make a profit. Iterate the idea until fully cooked on how much it will cost plus how it will make a profit. Create a presentation and pitch to anyone that will listen. Creating a physical model that people can touch will help. You are looking for both advocates that will help you and people that will finance it. Given that it's a new idea you'll need to do a prototype. Your first goal is to get the money for that. You might look for a foundation or benefactor that will help fund the prototype. Investigate the JOBS (Jumpstart Our Business Startups) Act as away to get the initial funds. This project's size demands that you spent all your time promoting it and seeking finance so you'll need to have the money to live while you're starting the project. Also you'll need to work on your presentation skills and persuasion skills. Look at Musk as your model. He's learned how to sell Tesla to both his investors plus the general public. Good luck! It would be nice to see something like this implemented.
