I believe that we should start to don't throw trash in the streets even if it's a little plastic, respect the natural areas and don't bother the trees or the plants with trash or constructions, be carefully with it, if don't have any other option and you need cut the tree or the plant, you should plant two plants or trees for every one that you cut down. Save water, brush our teeth with a glass of water, don't take a long time to take the shower, don't wash with much water. Reuse the water, when we wash the dishes or the clothes we can reuse it to pouring water into the bath or watering plants. In rainy weather pick up and store it.
