Answer:  Lichens affect every species in the ecosystem, in 2013 Russia had a dramatic lichen die off which caused 61,000, 20% of the entire reindeer population to die from starvation. And with fewer deers, the bears and wolves also suffered from the loss of lichens and if it takes a long time for lichens to grow back in an ecosystem, animal declines may take years if ever to be corrected.  Lichens serve as a basis for several food chains, especially in artic communities.

What first spurred research into what has now become green building?
Ghella [55]
San Francisco has an opportunity to reap tremendous economic, environmental, and health benefits by adopting recent advances in “green building”—benefits that will only increase in value over time. Many standard building design, construction, operation, and renovation practices are outmoded, inefficient, costly, and have adverse health and economic effects. The shift to new, environmentally sensitive practices would maintain San Francisco’s status as a leader in urban planning and environmental innovation. A shift to green buildings is also vital to enhancing San Francisco’s livability for its residents, workers, and visitors.
