What is your view on the coronavirus?
Koert van Mensvoort: The virus makes us aware of other lifeforms with other perspectives, desires and needs. It also teaches us that we are one humanity. These viral invaders don’t discriminate on the basis of nationality, race, income, social status, political or sexual preference. We are together and must work together to overcome. Stay safe.Comment
