Poor article that, based purely on a big city-centric viewpoint and incomplete research.
Lack of suitable nesting sites for wild bees is a much bigger issue in built up areas.
The easiest, most natural and by far cheapest way to do beekeeping is using homemade top bar hives, preferably with recycled site ply boards, cut down planks etc. Not sure how long I've been doing it , maybe 12 years.
As a pragmatic environmentalist I like having the bees to watch and look after, and take very little honey, as that is their winter stores. I feed them a specialist bee food or make up my own fondant mix if they are low. I had to move my hives as their ability to collect enough reduced over several years due to building development around where I lived. Picked up again as soon as I moved them to a better location.
Recently had a discussion with a Master Beekeeper who didn't like the idea of importing queens and colonies - risk of diseases and hive beetle etc coming in on Italian bees, which is a risk, but she had 60 + hives/colonies, & set aside breeding colonies, & didn't see the problems for small beeks not being able to do the same. I buy Slovakian queens if I need to, you need a large concentration of hives and bees to successfully breed). Conversely, she was obliged to strip honey and wax off her hives to sell to pay for the costs of her traditional hives & kit. My costs are negligbIe, made my own headnet, don't use or need a smoker, and only recently bought a bee suit for less than £20. Biggest expenditure was probably my local Beek club membership which I've dropped now.
