Slogans are a quick and simple way for people to inform others of a cause. Some examples of slogans for saving wildlife would be: Wildlife Keeps the Earth Wild, Saving Wildlife is Saving Our Future, Strive to Keep Wildlife Alive.
In the general context of 'Health,' a variety of appropriate health-slogans for kids may be created. One holistic slogan would be, 'Get healthy, get happy!' Countless particular slogans are also possible, of course, such as 'Brush -- and you'll shine!' or 'Exercising is cool!'
