The world does not need another disclaimer. What it does need however is a move away from a "where there's a blame, there's a claim culture". This suing culture, which is becoming increasing prevalent, is the reason behind so many amazingly positive projects not being able to happen. School kids cannot go on trips to organic farms if there is the slightest risk to their well-being nowadays. We ask, 'What about the guaranteed risk to their well-being if they are denied the chance to go to the farm and never learn to grow good nutritious chemical free food?'.
Listen to your heart. If you think something jeopardises your safety, obviously don't do it. If you decide to do it, take responsibility for it and don't make the world anymore afraid than it already is.
