The 75 Hard Challenge can be adapted to promote environmental awareness by encouraging participants to adopt eco-friendly habits and practices. The program's structure encourages participants to engage in daily activities that reduce their environmental impact, such as reducing waste, conserving resources, and supporting sustainability. By committing to these habits for 75 days, participants can develop a deeper awareness of their environmental footprint and make lasting changes that benefit the planet. The challenge's emphasis on discipline and consistency helps individuals stay on track with their environmental goals. The daily reading habit can include books on environmental sustainability, providing valuable insights into living a more eco-friendly life.
