The problem is bees are wanders/ roamers that roam vast distances. doing what they've always done. collecting necter and pollen on plants that are 1 not native to the area and therefore do not help them much. and 2 are treated.
add to it they are attracted to the chemicals that harm them, and add to that people who make the decidions ( I wont mention any names here but you know what i mean) don't care about anything . they only want to get rich.
unless big changes happen again i wont say what. I don't think they have much of a hope after 2040 honestly. domesticated ones maybe because the hives can be carted off away from the sprays. but not wild bees.
still i plant things in a community garden away from sprays because i care about the earth and its creatures.... sigh.
