You can do a lot to stop animal cruelty (also- Tips on education)
One of the most powerful tools we have for preventing cruelty to animals is education. It is important to plant the seeds of kindness in children early, and to nurture their development as the child grows. Children not only need to learn what they shouldn’t do, but also what they can and should do. When children see that their pets are happy and loving, it will make the child feel good, too. This in turn will help the children care for their pets’ feelings.
However, since people don’t always realize that they are being cruel, adults need education, too. If you are not a teacher, please urge your local schools to integrate humane education into their curricula. If you are a teacher, bring humane education into your classroom. To help you, your local shelter may have outreach programs, education materials, camps, etc. .. read more from the American Society of Prevention of Cruelty To Animals .
