The renovations were aimed to revitalizing residential neighborhoods and communities with elements of functional design and ecological functions.

Severe storms, climate change, pollution, habitat alteration and rapid population growth threaten the ecological functions that have supported coastal communities throughout history.

Each trophic level contains unrelated species that are grouped together because they share common ecological functions, giving a macroscopic view of the system.

This means that members of a trophic species share many of the same kinds of ecological functions.

However, maintaining all ecological functions, natural services and cultural values will likely require conservation of significantly more than 50% of a landscape.
