Here's a breakdown:
* Wood Pulp: Trees are processed into wood pulp, which is the main ingredient in paper.
* Fibers: Wood pulp is made up of cellulose fibers, which are strong and flexible, making them ideal for paper production.
* Other Sources: While trees are the main source, there are other, more sustainable options like:
* Bamboo: A fast-growing plant that can be used to make paper.
* Recycled Paper: Used paper can be collected and processed to make new paper.
It's important to note that sustainable forestry practices are crucial for ensuring a steady supply of wood pulp for paper production without harming our forests.
