What are the little things you and your children can do to be an environmentally-conscious Filipino family?

We love biking by the bay near Mall of Asia, whenever we do, i tell my kids to pick up plastics they see along the way. Also, wenever we go to the beach, i tell them that garbage (like bottles, cans, and plastic waste) are not part of the sea and that they destroy the natural habitat of sea creatures. This way, they will learn not to throw waste anywhere and help clean up.
