The air transparency in Australia is particularly high, and the blue sky, white clouds and sky can be seen from afar. Another feature of good air quality in Australia is dust-free. Visiting the park, from morning till night, shoes are spotless. The locals proudly say that their leather shoes can be polished for a month and their shirt collars will not turn black for a day.
Dust-free is because there is no dust in the construction site, there is no man-made destruction in the desert area, and there are many dust reduction measures. In Sydney, Melbourne, Brisbane, Gold Coast and other places, you can see sawdust covered with roots in public green spaces, residential areas and roads. Under the fitness facilities in public places, there are also sawdust bedding. Local friends said that sawdust covering topsoil can not only prevent dust, but also conserve water, create living conditions for microorganisms, transform sawdust into organic matter and provide nutrients for trees.
Australia has a series of mandatory regulations on greening, such as units and individuals must be responsible for greening in front of and around the door. If you don't do it, the relevant government departments will do it for you and send you the bill. Greening is given priority to with nature, there are no roads and streets, and it is a unified tree species. A lot of greening ensures the environmental quality. In 2004, Australia ranked third among the countries most suitable for human habitation in the world, second only to Norway and Sweden.
4 months and 7 years
There are more animals in Australia than people, and even more kangaroos are regarded as the symbol of Australia. There are about 70 million kangaroos there, more than three times the total population of Australia. Kangaroos have a special function, not only have a baby bag that is warm in winter and cool in summer, but also have a peculiar adjustment ability. According to the living conditions, female kangaroos can be pregnant without birth. If the environment is bad or the food is not enough, the female kangaroo can wait for the fetus to improve its reproductive ability.
Too many kangaroos will have a negative impact on grassland and ecology. Therefore, the Australian government allows 3% kangaroos to be killed every year. But Australians don't eat wild animals. Kangaroos can be seen jumping around in the Woods and grasslands along the road, leisurely foraging.
Compared with kangaroos, koalas that feed on eucalyptus leaves are much less. It is naive, sleeping for 20 hours a day. Koalas are not easy to see in the wild. Therefore, it is more protected.
Whether kangaroos or koalas, Australians attach great importance to the protection of biodiversity. Only a small part of the rainforests in Keynes and Kullanda have been developed into tourist areas. The main tourist project is to explore the tropical rain forest in an amphibious vehicle left over from World War II. According to reports, the aerial ropeway built there took only four months to build, and the environmental protection approval took seven years. They think that not developing is the best protection.
Eucalyptus Kingdom and Coral Kingdom
Eucalyptus is the national tree of Australia. This fast-growing tree species known as "Youjiali" has spread all over the world and attracted the attention of global ecological experts. It is said that there are more than 500 kinds of eucalyptus in Australia. On the expressway from Sydney to Canberra, you can see a large area of eucalyptus forest.
Blue Mountain is a national forest park and a world natural heritage. Because the eucalyptus forest emits blue light under the sunlight, it is called the blue mountain. Blue Mountain is 0/00km away from Sydney/Kloc. Because of the good forest vegetation, it is known as the "blue mountain". The staff of Blue Mountain National Forest Park introduced while walking. There are small shrubs, small flowers and plants, as well as unique wildflowers and unique wild fruits in Australia. They kicked away the sand and showed us the environment where eucalyptus grows. There is no organic matter in the sediment. The land here is barren, and only eucalyptus can grow. Without eucalyptus, many parts of Australia may become deserts.
Australia's Great Barrier Reef is the largest coral system in the world, with a total length of 2,300 kilometers from Queensland in the south to Fort Bend in the north. Soft coral 65,438+0/3, hard coral 360, fish 65,438+0,500, seaweed 500, manatee 65,438+0,400, commonly known as mermaid. There are about 90,000 animals in Australia, including at least 800 echinoderms such as starfish and sea urchins, 22 seabirds, 32 shore birds and 30 whales.
It is not difficult to see from these figures that the Great Barrier Reef is a colorful underwater world. There is only one floating platform on the sea, and there is a small piece of sea around it as a tourist area. Visitors can take a helicopter tour, dive into the seabed to enjoy the gift of the coral kingdom, and take a glass boat to watch the ever-changing underwater world. You can see beautiful coral reefs, tropical fish, big turtles, big sea cucumbers, big pearls and so on across the boat.
Keynes had a peaceful three holy bays. On weekends, local residents like to play barbecue at the seaside, and they can catch seafood directly in the bay. At this point, the manager took a ruler to measure crabs. Anything that doesn't meet the standard is put back into the sea. When we passed by, we happened to see a sea crab weighing about one catty released into the sea. According to reports, you can only catch five crabs every day, and you will be fined if you catch more. It is the residents' consciousness that makes Australia maintain a good ecology in the process of development.
