In our school, we have a ban on all milk containers, sippy drinks, cans bottles, we can only bring in drinks in reuseable bottles! Our whole school does that so that is alot of waste being saved . Ithink every school in the United States should do that and that would reallllllly make a difference to our planet. At our house, we don't use plastic bags either when we go grocery shopping, my mom has cloth bags that we take with us, and the store even gives us I forget how much but they give us credit for not using the plastic bags that they have there.
