Photosynthesis.
I was reading a book about energy.
If you think deep of all the things you eat, it´s easy to find that the main origin of everything is a plant. 
Let´s say you are eating a steak, well the cow ate before grass and some seeds.
Now you are eating chicken, well the chicken ate some seeds also.
Now you are eating fish, well the fish ate other fish or some placton, or some algae.
All the things we eat, are solar energy converted in let´s say (for sake of simplicity) “packets of energy” in form of macromolecules by plants by means of Photosynthesis. Then, we eat this packets of energy from plants, or we eat this packets in form of chicken, fish steak or anything.
I believe Photosynthesis is a corner stone process of life. 
I believe in Photosynthesis. 
Isaac Asimov, wrote a lot of books, I highly recommend to read this author, He is great at explaining things in simple ways.
