Final answer:
The Mass Trespass in the Peak District helped to raise awareness about the right to public access in the countryside, leading to the creation of National Park legislation and the 'right to roam' under the Countryside and Rights of Way Act 2000.
Step-by-step explanation:
The Mass Trespass in the Peak District accomplished several significant outcomes, influencing public and political perception toward access to the countryside. The event highlighted the unfairness of the British class system where large landholders had exclusive use of rural landscapes, preventing working-class people from enjoying the right to roam. Despite the immediate repercussions, which included arrests and convictions of participants, the mass trespass is credited with raising public awareness and contributing to the development of the National Parks legislation and the eventual establishment of the 'right to roam' in certain areas under the Countryside and Rights of Way Act (CRoW) 2000. This marked a substantial shift in favor of public access to previously private land for recreation and enjoyment, setting a precedent for modern conservation and public access efforts in the UK.
