17.A MythIt is true that world population is growing,but this is not the cause of our current and future global problems.Believing this will cause us to ignore the real problem and risk long-term damage to our planet.
Let me start by explaining why overpopulation is a myth.For one thing,the UN Population Division regularly predicts population growth but provides a low variant (变量),medium variant,and high variant to factor in various possibilities.In the 2010revision,their high variant suggests that the world population will be almost 16billion in 2100,but the low variant predicts it will peak at 8billion and decrease to just over 6billion by 2100.In most cases,it is the low variant that has come true in the past,suggesting the same will be true of their future population predictions.In addition to this,the size of families is actually decreasing.
For another,if the Earth is overpopulated,there needs to be insufficient (短缺) food,water,and space for humans to live.However,Indian economist Raj Krishna estimates that India alone is able to increase crop produce to the point of providing the entire world's food supply.The World Food Programme confirms that there is sufficient food grown to feed the world and there is the same amount of fresh water on the planet now as there was 10,000years ago.So how is it possible that the number of people in the world is affecting our planet?
Therefore,it is not an increase in population but an increase in consumption that is a severe threat.Materialism and overconsumption are facts of life for everybody in the western world,as possessions reflect a person's status in society and people strive to obtain happiness through owning the latest fashionable goods.Not only that,but waste is a common occurrence which has a huge effect on our resources.It is a sad truth that 80% of the world's resources are currently used by just 20% of the world's population.
Our overconsumption must be addressed now to make our lives more sustainable (可持续的) and avoid continuing the terrible damage to the environment we are causing.The key is education.If we do not work towards this but instead focus on the wrong issue,we may find ourselves living on a planet that can no longer sustain human life.

What do former American president Bill Clinton and rock musician Pete Townshend have in common.'?Both men have hearing damage from exposure to loud music,and both now wear hearing aids as a consequence.As a teenager,Clinton played saxophone in a band.Townshend,who has the more severe hearing loss,was a guitarist for a band called the Who.He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.
Temporary hearing loss can happen after only 15minutes of listening to loud music.One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones.One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.
"What happens is that the hair cells in the inner ear are damaged,but they're not dead,"says physician and ear specialist Dr.Sam Levine.According to Dr.Levine,if you avoid further exposure to loud noise,it's possible to recondition the cells somewhat.However,he adds,"Eventually,over a long period of time,hair cells are permanently damaged."And this is no small problem.
What sound level is dangerous?According to Dr.Levine,regular exposure to noise above 85decibels (分贝) is considered dangerous.The chart below offers a comparison of decibel levels to certain sounds.Here's another measurement you can use.If you're at a rock concert and the music is so loud that you have to shout to make yourself heard,you're at risk for hearing loss.That's when wearing protective devices such as earplugs becomes critical.
The facts are pretty frightening.But are rock bands turning down the volume.'?Most aren't."Rock music is supposed to be loud,"says drummer Andrew Sather."I wouldn't have it any other way.And neither would the real fans of rock."
Continued exposure to loud music and the failure to wear earplugs can lead to deafness,according to Dr.Levine.He states,"There's no cure for hearing loss.Your ears are trying to tell you something.That ringing is the scream of your hair cells dying.Each time that happens,more and more damage is done."
