Take heart. There are lots of terrible things in the world - Poverty, disease, injustice, natural disasters...Thankfully, good FAR outweighs the bad: Love, Faith, Art, friendship, healing, creativity, community, innovation, beauty and renewal to name just a few. Focus on the good. Relish in the countless expressions of goodness. Work hard to preserve, protect, and advance them.
Avoid bird seed or pet food near your home. It attracts mice, rats, ticks, etc. keep bird feeders that use seed a good distance from the house. Try liquid feeders near windows. Or use a feed tray or hulled seeds (little waste.)
