We all know bees are in decline as a result of a range of factors: habitat loss temperature change disease colony collapse casued by common agricultural and domestic herbicides such as glysophates, that cause bees to become disorientated. While we often think about bees as pollinators for our food sources, we should not forget that they are also a promotor of vegetation generally, and, the more vegetation, the less climate change. In one recent study it was concluded that mitigation of bee loss in the Amazon would most likely promote reforestation. https://www.scidev.net/global/news/bees-boost-brazil-s-forest-restoration-scientists-say/ So saving bees helps forests, too. It is not quite 'save the bees and you will save the world'. But if we let the bee decline continue, then saving the world from a complete ecological collapse will be a lot lot harder. You can help. A group called Save the Bees recently pointed out how we can all do one thing to help bees. They said: "Native bees are expected to struggle not from the increasing temperatures but primarily because of the clearance of available habitat. Impervious surfaces and buildings are replacing soil and vegetation burrows, their homes. You can help your local natives by placing a bee hotel in your garden and planting native species. All bees will benefit extensively from having an available water source to drink from. You can place a shallow dish filled with water out in your garden or on your balcony with stones and sticks in it for the bees to land on. This simple gesture can be done by anyone and is a great step to helping bees keep their homes and themselves cool."
