During our science center trip, this poster caught my eye as it reminds me that there is hope in our world...for our beautiful blue planet. Last week I read in National  Geographic how we are yet not ready to land and live on the moon. It just made me think, my goodness-here we live in such an amazing  world already, where we don't have to worry about our heads exploding from space pressure or not having enough water or oxygen-it's all a matter of taking care of it so we won't have to move into another planet...argh...it's only we cared just a little more about our earth🙇
