Preventive oriented primary healthcare Vs medical intervention

It is obvious the name "health" associated with clinical settings (hospitals, clinics, etc) which is dominated by medical interventions. The cost of some medication is rocket high and costs the NHS millions of pounds and drains resources from other sectors. Focusing on preventive oriented primary healthcare at local and national level is more important than ever. For example, one of the public health issues in the western countries especially in UK is obesity. This is a direct result of lifestyle such as sedentary way of life or lack of exercise. Deprived areas in different local authorities are victims of this 'pandemic' that can be preventable with low-cost investment in those areas. For example, beautification of parks and play grounds which are short-walking encourages residents to walk, exercise and refresh themselves which has a positive impact on their physical and mental health. Sustainable healthcare can be achieved in such deprived areas with a small investment than spending millions on medicines and medical intervention.
