START GETTING GREEN WHEN COOKING

When I read the newspaper or watch the t.v news, I feel this need of doing things before there is nothing else to do. So I realize, that I have to start where I am.
I cannot go to the United Nations to explain my concern about the world, but I can save energy while cooking.
I can separate organic trash from inorganic.
I can use the water where I boiled vegetables to water my garden.
I can bring my reusable bags to the grocery store instead of using plastic bags.
I can wash my dishes instead of using plastic dishes.
I can figure out different ways to prepare food with the leftovers instead of throwing them away. I can take advantage of cooking a big quantity of food, portion it and freeze it.
I can also separate the frying oil in a bottle and put it away in the trash.
I can rinse used cans before I throw them away.
I can write a grocery list to buy only what I need.
I can plan healthy menus for my family using seasonal and cheaper ingredients, and I´m sure you can do this and a lot of other things to get green while cooking, so what are you waiting for? It´s your world too!!!
