Mortgage debt causing older Australians distress and worsening mental health
Since the late 1980s after accounting for inflation, the mortgage debt among older Australians has increased by 600 percent and nearly half of home owners aged 55 to 64 are still paying off a mortgage. According to Australian housing and Urban Research Institute (AHURI) said more Australians are facing difficulty to pay off the mortgage before retirement. The older Australians owe the bank more than the value of their home. The house price has risen triple, but the income fall behind and grow slowly. The number of older Australians are increased to be stuck in paying private rental when they are no longer work or they cannot afford to buy a home in the first place. Also, more retirees use the superannuation to pay off mortgage, they would likely to be depend on the age pension. As a result, it will affect on the government fund and age pension system.

The extinction of animal is a natural process, but human has greatly speed up of process which makes the animal disappear. There are two groups of endanger species such as critically endangered and simply endangered. The simply endangered are the orangutan, the black rhinoceros and the Sumatran tiger. The critically endangered are the Asiatic lion and the Pygmy hippopotamus.

Note taking:

-The increasing of the world population and global economic have been affected the earth. As a result, many species have been killed in a large numbers than previously.
-Climate change, hunting, pollution and over use of animal are an important key factor that threaten nature.
Brief summary:
According to UN report, human action has produced strong impact on the nature of the earth. It eliminates most of the plant and animal species which use to live on earth. It also causes climate change which impacted on the living life on earth. Also, due to the increase of world population and global economic, more land clearance to turn into plantation, as well as affected the earth and kill many large number of species to nearly extinction.
Personal reflection:
This is true that say "Every living thing on our planet depend on another for survival". If we lost one thing, we would suffer because everything is connected to each other. Therefore, we should think of the nature around us and protect it for another generation to have chance to live in wonderful view that we had it in the past. Educate young generation about the nature and advantages of it. From reading about nature crisis, I am stocked that human action is killing the large amount of species nowadays. We should put more effort to protect the nature and do not destroy it. We should help to protect the nature by using environmental friendly products, stop cutting down tree, do not buy animal skin products and eat more vegetable than meat. Also, government should do more to stop the illegal trade in wildlife and help to protect land for animal habitat.
