Mark Hinsley defends the importance of trees not only to our landscape but critically providing shelter for homes, crops and prevention from flood damage.
When you were young did you have a big older friend or sibling? You were a little in awe of him/her, even a bit afraid, but this person meant that the bullies would leave you alone.
Consequently, you readily accepted the slightly risky element of the friendship in return for the much wider protection from harm from which you benefited.
Big trees in towns are a similar proposition.
