Throwing waste into a volcano sounds like a neat way to get rid of at least some of the mountains of waste we produce, but in reality it is a bit more difficult and dangerous!
“For a volcano to be able to effectively digest waste material it would have to be actively erupting,” says Dr Alanna Simpson, a researcher at Geoscience Australia.
We don’t have any active volcanoes in Australia. Throwing garbage into a dormant(休眠的) volcano, such as Mt Gambier in South Australia, as a way of removing waste would be useless as it may not erupt for hundreds of thousands of years.
“Putting waste into this volcano would destroy its natural beauty and appeal,” says Simpson.
Of course, a volcano that is actively erupting is a pretty dangerous place to hang out. Approaching the mouth of a volcano with a garbage truck full of rubbish would be extremely hazardous.
“Not only is there lava(熔岩), such as with the Hawaiian volcanoes, there may also be poisonous gases, rocks and lava being erupted into the air,” explains Simpson.
In fact, erupting volcanoes are often considered so dangerous that people are typically moved out from around the vent(火山口).
Volcanoes, whether active or dormant, are also often considered places of extreme natural beauty and many are protected as national parks.
So throwing our waste into volcanoes isn’t the simple solution it might seem. Maybe we should just think about using less and recycling more.

巧学巧练系列答案Not long ago the movie 2012 came into screen. The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster. Luckily, they are just the director’s imagination, but the present situation is not heading a positive direction, either.
Take my own experience in Alaska as an example. Once I took a trip to the glacier. Along the way there stood signposts marking the snow lines of different years. They started from the foot of the mountain, but it was at the top when I finally saw melting glaciers(融化的冰川). My heart ached seeing the beautiful blue ice melting at every second.
Sad but true, they are the effects of global warming and the result of our human impact. Furthermore, each year the rising sea level will kill 56 million people, and that's about the population of the en tire Italy. According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water.
Our fortune is in our own hands. It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now. Contribute a little to energy saving by using more efficient light bulbs and less hot water. Let recycle become our habit by thinking twice before throwing something away. Let us take public transportation as our first choice when going to a certain place. It might cost more time for now, but it' s to the benefit of a permanent future. Take care of every tree and grass around us by watering them or simply just avoid destroying them．
In a word, small drops of water make a big ocean. The earth does not belong to us. On the contrary, we belong to the earth. Please bear in mind that the earth is our home. It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming reality．
