Currently earth seems to be going through mass extinction of many species (Holocene extinction) due human activity. In this background, it is vitally important that we extend our compassion towards animals. Some of the ways we can do that is:
Provide food/ water to animals around places we live
Take an active role and help an injured/ sick animal
Choose a life style which avoids those products which lead to cruelty towards animals
Make other people aware about the importance of compassion towards animals
Find details about the NGOs working in your area/ city for animal welfare, so that you know what kind of care they provide and wherever necessary take their support in helping an animal
When you go on vacations, plan responsibly so that you do not reinforce those professions which abuse animals
Compassion is the basis of morality. ― Arthur Schopenhauer
