1. Falling from the cliff
1.1 Case Study
On April 1, 2007, a 48-year-old woman was killed after plunging 50 meters from a cliff while hiking on the rugged Lion Rock. She planned to climb over Lion Rock along an unnamed path with 2 people. However, they got lost along the path. So, the woman climbed upward along a rough cliff to try to find a way out. Unfortunately, she sipped and fell 50 meters down the cliff. She suffered severe injuries and lost consciousness. Later, she was declared dead in hospital. 
1.2 Possible causes
For hikers, they may need to bear part of the responsibility to protect themselves. Some hikers may neglect the danger while hiking.
Firstly, some people may walk too close to the edge that they may accidentally fall down when they are careless or step on little rocks.
Secondly, some people may wear unsuitable shoes while hiking, like high-heels and slippers. These kinds of shoes cannot prevent slippery and cannot protect their ...view middle of the document...
The algae would make the surface of the rocks become smooth and slippery. Also, the rocks and roads will become wet and slippery after raining.
Thirdly, the surfaces of rocks or roads might be destroyed b human, weathering or erosion. When people step on the broken surface, they may lose balance and fall down.
Firstly, the government should educate people to raise their awareness of being careful while hiking and help them to develop safety mindsets about hiking.
Secondly, people should be told what to wear and what to prepare before hiking. For examples, they can use hiking poles to help balancing and they should wear athletic shoes or hiking boots to prevent slippery.
Thirdly, the government may install some rails or barbed-wire fence near the edges of some popular mountain trails or some locations that accidents always happen to protect the hikers.
2. Falling into the water
There are many streams around the country parks or mountain trails. Some of them are potential hazards for hiking accidents. Usually, there would not be any rails around the streams and people may fall down into the streams if they are careless.
2.2 Possible causes
Firstly, people may neglect the danger from water. They would be rather careful while walking along the cliff than walking along the stream.
Secondly, parents may allow their children to play along the streams on their own and children may take the stream as a playground.
Thirdly, hikers may take rest and sitting along the side of the streams. They may fall down to the stream in accident.
Firstly, people should be reminded that the streams are also dangerous if you walk too close to them. There is also a risk to fall down into water.
Secondary, parents should take care of their children even while they are taking rest and should not allow them to play along the streams. They should start teaching children that the streams are dangerous since they are young.
Thirdly, the government may install rails or barbed-wire fence to prevent people falling into the streams accidentally.
