While nature lovers across the world wish all humans to realize the significance of their natural surroundings ,many Australians are turning caring for the environment into a way of life.

Julie Astonis ,an Australian housewife in Brisbane is one such example, Even though autumn is approaching Australia’s Brisbane in April, one can still watch colorful blooming （盛开的）flowers in Julie’s little garden, as she tells that in her community, “Each of us has a beautiful yard, The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden.”

“Gardening is the most popular club in our community,”she says, “A lot of retired people don’t just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training , So you can see that flowers continue to bols-som in our gardens throughout the year.”

Talking about her people’s sense of care for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog’s waste, “In our community ,you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass,”says Julie with a smile,“Taking care of the dog’s waste can also help to develop children’s sense of responsibility!”

As to protecting water resources , the Australian government has made strict rules for families, Julie says, “We certainly would not use tap water to water the flowers!”She ways almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, connect the water tank with their toilets.
