Separate the trash. Since childhood it is good that children learn to separate waste so they can be recycled. Teach them what is thrown in each bucket and why it should be done that way.

Use products that can be reused. There are many products that can be used several times to protect nature. For example, use cloth napkins instead of paper napkins.

Turn off the lights. It seems obvious, but we don't realize how many times we turn on the light of a room we don't occupy. Get your children used to turn off the light and when you leave home, check that everything is turned off.
