The Environmental Protection Agency estimates the average American throws away about 70 pounds of textiles every year. While many of us know lightly worn clothes can be donated to charities like Goodwill and the Salvation Army, what do you do with old bath towels, worn sheets and blankets? Give them a good wash and donate them to your local animal shelter. Since many pound puppies and kittens have to sleep on concrete floors or cold metal cages, any warmth from old bedding, blankets and towels will be put to good use. And while you’re at it, pick up some meat-based baby food at the supermarket: Shelters use this food to feed malnourished animals in an effort to nurse them back to health.
