If we’re careless, it will fall and break.
The Knife symbolizes the threat of violence and war.
The Wheat symbolizes the threat of famine and material hardship.
The Champagne flute symbolizes the happiness and pleasure of those who inhabit this world.
The Snowglobe symbolizes the world itself – the planet, the ecosystem, etc.
You don’t have to be careless yourself. Someone else can be careless on your behalf, with someone else’s money, and you’re going to be the one sweeping up the broken glass. The most responsible person in the room loses when children play careless games.
Don’t get jerked around by the INVISIBLE HAND.
