We cannot protect them, but the earth has faced threats before and it is still here - it might change - perhaps catastrophically - but it will continue. I think the best we can hope for our children is that they will do something positive for change.They cannot all be Greta Thunbergs, hopefully one of her is enough, but we can all do something, beginning with understanding what is happening and why. One of the root cause of what is wrong, is selfish materialism - wanting the same as our friends etc and not caring what the cost is to the earth and its inhabitants around the world, another big problem is inequality of wealth. . Becoming someone who knows and cares, who can stand apart from the crowd, and find happiness without relying on man made objects to distract them, will give the young ( and old) the tools to survive mentally and cope with what is to come. It is already too late to prevent some of the consequences of our actions, but we can help ourselves and others to assist in putting the world back onto a positive path. Knowledge, will and action. Understanding that all the countries and people on earth are interdependent, that earth’s resources are finite and should be shared equitably, and sustainably - doing what we can to adjust our own lives so as not to impinge on others, joining with groups and other people who care, to lobby (non violently) and work for change. There are many positive signs out there. supermarkets and manufacturers are getting the message, now we need to find (or become) the politicians that will make the right changes in the face of opposition from those who have a vested interest in leaving things the way they are. We will all die sooner or later, but our legacy will live on.
I think someone got out of the wrong side of the bed


Yes, we can and should acknowledge the problems the world has and all do our bit towards ameliorating them. In my experience, many people are already doing that, and change is being forced onto the likes of supermarkets by people-power. There’s always more to do but small steps are better than standing there hand-wringing.
