Answer: Cycling Cardboard is something we must all do for the sustainability of trees because paper or cardboard are considered to be the most renewable alternative since they are bio-based, recyclable-more than five times on average-and biodegradable. Most of the paper is made with forest trees, although it can also be produced of bamboo. In economic terms, companies and entities recycle products like paper because they also save money on pollution reduction. Composting is also beneficial for the world or local cities, as it helps preserve valuable energy, decreases waste from the manufacture of new goods and grows the economy.
