Chemical bonds are really important for making biodegradable materials. They help decide how strong these materials are and what they are like.

1. Types of Bonds:

   • Covalent Bonds: These bonds make the materials strong. For example, polylactic acid (PLA) has a special bond between carbon atoms that gives it strength.
   • Hydrogen Bonds: These bonds help the materials absorb water, which is important for breaking them down in nature.

2. Statistics:

   • Every year, about 300 million tons of plastic is made. Shockingly, 8 million tons of it ends up in our oceans!
   • If we use biodegradable options, we can cut down plastic waste by about 30%.

These chemical bonds help materials work well and eventually break down in the environment.
