As the city population increases, more of the environment is lost to city building. This causes stress for the animals and plants in the area.
There is a community need for ecology restoration. Many animals and plants are lost due to growing cities and buildings in Sydney. This is difficult for locals, as they have to cope with the loss of familiar animals and plants as a result of the building.
Sydney is a very popular city for people when choosing where to live in Australia. To cope with growing populations, the city is continuously expanding.
This need is being met by increased conservation efforts such as protected wildlife sites like the Botanical Gardens and the Blue Mountains. These protect these areas from having cities expand into them, giving the plants and animals a place to live alone and undisturbed.
