Trees! We need them and we would not be able to live without them, but they can be deadly. In the years 1968 to 2005 there have been 69 deaths  by falling limbs from trees. So caution must be taken when in and around trees. Building a home near trees is certainly something that many do without thinking through the possibility of limbs falling and causing injury and/or damage to their home. Trees drop limbs to survive and it is part of their life cycle so this needs to be kept in mind when in and around them.
