Buy organic, seasonal and bee-friendly foods
This may seem obvious but emphasize it for better understanding. You'll pay a bit more, though, for organic and seasonal produce from local organic farms. However, this action will bring many benefits. One of them is to support and encourage local producers to cultivate bee-friendly agriculture. Especially organic gardens that do not use pesticides. From such small things, bees will face less danger.
Be careful! Organic honey (including BIO-labelled organic honey) from stores is unlikely to be organically sourced and follows sustainable beekeeping practices. For example, this honey is blended with organic honey sources imported from countries outside Europe. In these countries, organic standards are very different from those in Europe. Even among European countries, there is no uniform standard on this. So you should always check the label when you make a purchase.
