If we take to many of these natural resources , they will run out . This is why it´s important to reduce , reuse and recycle.We should try to reduce the amount of materials we use and the waste we produce. Buy products with little or no packaging, then put the packaging in the correct recycling bin.We can reus plastic shopping bags. We can clean packaging such as boxes and jars and use them again.Recycle mean to make something new from something we have used.We can recycle glass, aluminium and many other things, too.
