WebAccording to The National Institute on Aging, every year 30% of people over the age of 65 will sustain a fall, of which 10% will result in a serious injury. 67% of fall fatalities are among people aged 75 years or older. People over the age of 85 are 10-15 times more likely to experience a hip fracture than are people aged 60-65 years. WebIndirect impacts on the environment are these which are not a direct result of the project, often produced away from or as a result of a complex impact pathway. The indirect impacts are also known as secondary or even third level impacts. For example, ambient air SO 2 rise due to stack emissions may deposit on land as SO 4 and cause acidic soils.
