After I compared Encarta encyclopedia with Britannica encyclopedia, I found that:

For Encarta encyclopedia:

 The website is not reliable, it allows everyone to edit it.

  It doesn’t show the author information.

  It doesn’t have any picture.
  Has reference list.

For Britannica encyclopedia:

It provides the author’s name

Public people are not allowed to edit it.

It has the picture of the character.

Does not have reference list.

The similar of two types encyclopeida
- have clear headline

Housing affordability in Australia

This bar chart illustrates the average house prices in capital cities in March 1980 and March 2016 in Australia. In general,  the house prices have increased enormously since 1980.   In 1980, the house prices are steadable and affordable. However, in 2016, the house prices rocketed and people's housing affordability was decreased a lot. Sydney made the highest house prices in both 1980 and 2016. Melbourne has become the second higher. Nowadays, many people who live in Australia are struggling to buy their own houses, especially in Sydney.

                                                   Threatened and endangered species


summary:
 
          The main reason for world changing rapidly  is human population explosions, greed, pollution and disease, which impact animal live. The extinction of species is nature process but human accelerated it. Animals under risk of disappearing are called threatened, which may be endangered or vulnerable. Without any protection, the animals could become extinct within 10-20 years is called endangered, which is formed from critically and simply endangered. Without any protection, the species extinct over a long period of time is called vulnerable.

                      Breakdown in coral spawning places species at risk of extinction 

Four points of the article

      *  Coral reefs are  among pf ecosystem on our planet, which  are under threat of extinction.

      * Some study and research  find that the highly synchronized spawning  events have changed and decreased in successful fertilization, led to creating circumstances  extinction .

       *  Compare with decade ago, most abundant coral species erratic in spawning synchronize. the breakdown spawning cause coral species extinction through reproductive failure.

       *  The main reasons for breakdown in spawning synchronize are found:

        -   climate change.

        -   human activities.

Summaries:

     Coral reefs are among the most diverse and productive ecosystem on our planet, which reproduce by broadcast spawning in open water are under threat of extinction. Some study and research  find that the highly synchronized spawning  events have changed and dramatically decreasing the chances of successful  fertilization. Also led to lack of recruits, stagnant aging population and creating circumstances for extinction .Compare with decade ago, most abundant coral species have become erratic in spawning synchronize. After the long term monitoring found that the breakdown spawning can even cause the most abundant coral species extinction through reproductive failure.  Two of the main reasons for breakdown in spawning synchronize are  climate change, which cause the ocean warming,  the rising temperature strongly effect coral reproductive cycles and endocrine disrupting pollutants- accumulating in marine environments by human activities.

personal point 

  People can do a lot of things to protect the coral reefs , save our ecosystem and planet. There are many things led to the climate change, which is due to human activities. Therefore, to avoid  the harm to the coral reefs people should not fish near a coal reef, do not liter on beach or ocean, plant more trees and reduce the carbon footprint.
