Hmmm, that could be a long list.
First there are the natural disasters. You name it, Hurricanes, Tornados, Earthquakes and Volcanoes.
Pick the area of the world and try to find an organization that is on the ground and donate time if you are local or money if not.
Then there are the social disasters. We got war, loss of human rights, healthcare so no shortage here. Vet the organization and if not sure give to a large blanket group to help out.
We still have groups that have suffered from the Covid-19 crisis. Loss of jobs especially in food service. So buy local and eat local. Forget the chains and go for the local restaurants. No shortage here.
And whatever you do and can do, smile and be friendly to all.
Have a good holiday, stay healthy and have a wonderful New Year.
Take a hike today.
