How can we live our lives without consuming so many products?

Instead of growing so much just eat bugs

I'm going to assume that by "products" you mean foods that have many artificial aspects like coloring and flavoring. To avoid these things you should try to find healthier or more organic alternatives. For example: If you have want to eat popcorn. Try to buy just the corn kernels than pop them at home yourself. You can add many different toppings like cheese or butter and salt. Hope that helped ^_^  

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
