Our long term future depends on us being able to grow and rear crops in a manner that respects the environment. Many invasive weeds are a sign of bad farming and soil neglect.
As we have found since the start of the industrial revolution when there is a blind dash for maximum dveelopment at the expense of human, or animal wlefare, after a while we realise what damage a blind dash is making to the world.
From the earliest Factory Acts of the 19th century that limited the exploitation of children down mines and in factories, each industry has gone so far and then been reined in when the cost to humans, animals and the environment is seen as too great. Agriculture has also to meet those limits. There are controls on the use of pesticides, now on biocides, and now we need to look at the damage that a mad dash for industrial agriculture, that is more about money than food, is doing to the land itself.
We are already producing enough food to feed everyone on this planet now and for the forseeable future. By the end of the century, and certainly in the next century we will see human populations falling. Poverty and starvation are political issues, not supply problems. In the Uk we throw away each day, more than enough food to give every single person in this country enough food. It is lack of money that leads to Food Banks, not a scarcity of food
