The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.
In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters.
Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels.
It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains.
A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.
As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

With the general standard of living improvingand the working week becoming shorter，more andmore people are able to make a holiday trip toplaces of interest. While many like to joinpackage tours fro convenience，I prefer to travel on my own.
I like travelling on may own not only because it costs much less but because it gives a great degree of independence and freedom. Travelling on my own，I’m my own boss；and can decide when to start on my way，where to linger a little longer and which spot can be skipped over to save energy or time for another spot. I can always adjust my plan. On the contrary，in a package tour you’re deprived of as much freedom as in a military base. At the sound of the whistle，you have to jump up from a sound sleep and，with heavy-lidded eyes，hurry to the gathering place where you are collected and counted to board a coach. At the sight of the little flag waving，you must immediately take yourself away from the scenes you are marveling at and follow the guide whose sole interest is to cover all spots according to him strict schedule，regardless of the weather or your health condition.
True，you may encounter inconveniences if you travel individually，for instance，getting accommodations for the night and finding a place for meals. But nothing can be compared with the freedom which is vital to a person who takes a holiday trip mainly to escape from constraints of his routine life.
随着生活的标准、工作时间的缩短，越来越多的人能够对旅行感兴趣。而许多人觉得方便想参加旅行团，我喜欢自己去旅行。
我喜欢自已旅行，可不仅因为它的价格要便宜得多，且它给了很大程度上的独立和自由。我独自去旅游，我是自己的老板；可以决定什么时候出发上路，在那里逗留更长一点的时间，可以跳过了一个景点节省精力和时间。我可以调整我的计划。相反，在旅游团的.话你可能被剥夺自由。在口哨的声音下，你要从酣睡中跳起来，眯着眼睛，赶紧去聚集的地方。在想逗留的地方，你必须让自己远离你你感兴趣的场景，必须他严格按照导游的时间表，无论天气或你的健康状况。
当然，如果你单独旅行，你可能会遇到麻烦，例如，住宿过夜，找地方吃饭。但没有什么可以和一个人度假旅行相比的啦，为了逃避日常生活的约束，自由比较重要。

The wind gently murmured,puffed and sometimes sighed like a summer breeze lifting the leaves along the livelong night.The cat was curling up quiet in her bed.The mouse was sleeping carefree in his gallery.The dog was lying swwet on the sofa.Even the earth itself was sleeping in tranquility,exept that some house door faintly creaked upon its hinge,telling us a remote inward warmth.Nature was at her midnight work with feathery flakes whirling down in the wind,as if she was showering her silvery seeds over the fields.
Finally I woke up.The floor creaked under my feet as I moved towards the window.The snow as warm as cotton was lying calmly upon the window sill and the stillness of the morning was extremely impressive.
The roofs were standing under their snow caps,while the eaves were wearing their glittering ornaments.The trees raised white arms to the sky on every side,and where there was a wall,there were some fantastic forms of snow stretching exhilarated in the dim landscape,as if Nature had carved her fresh desighs by night as models for man's art.
Silently,I opened the door and stepped outside to face the cutting air.The moon had already lost some of its glow and the land was bathed in a dull mist.A lurid light in the east proclaimed the approach of day while the weatern landscape was bleak with some spooky stillness like a wizard kingdom.What you could only hear was the creepy sounds,seemingly out of the hell----the barking of dogs,the hammering of blacksmith,the lowing of cows and the crying of pigs under the butcher's knife.
Gradually,the lurid light darkened and spread across the west.Every flower,every tree and every weed were bathed in the sunshine.Suddenly,it turned out that all the sounds were not for any melancholy they suggested,but for their twilight bustle which was too solemn and mysterious for me.
I moved on,treading briskly along the road,the dry and crisped snow crunching under my feet.
