人口与环境

①人类在地球上出现已经有二三百万年了，在很长的一段时间内，人口的增长一直是很缓慢的。从18世纪以后，世界人口的增长速度才明显加快起来。目前，地球上的人口达到了前所未有的数量。据统计，1990年世界人口达到了53亿。

②我国人口的增长趋势与世界人口的基本相似（如图）。以解放后为例，      ，翻了一番还多。我国是世界上人口最多的国家，我国人口约占世界人口的22％。

③人在一生中，需要各种各样的资源，如水、空气、土地、动植物资源、能源等。这些资源都需要从环境中获取。随着人口的高速增长以及人类消费水平的提高，人类必然要向环境索取越来越多的资源。然而，在人类赖以生存的地球上，环境为人类提供各种资源的能力是有限的。这样，人类不断扩大的需求与有限的资源之间便产生了尖锐的冲突。

④就拿耕地来说，耕地上生产的粮食是人类食品的主要来源，然而人类所拥有的耕地现状却不容乐观。地球表面的陆地大约只占地球表面总面积的30％，而耕地只占陆地总面积的11％左右，并且可供开垦而尚未开垦的耕地已不多。与其他国家人均耕地面积相比，我国人均耕地面积很少，只占世界人均耕地面积的1/3左右。随着人口的增长，很多耕地变成了住宅用地，再加上土地沙漠化、水土流失、土壤污染等因素，使人均耕地面积急剧下降。据统计，1951年，我国耕地有1．08亿公顷，人均耕地0．19公顷。到了1981年，我国耕地总面积下降到0．99亿公顷，人均耕地也只有0.10公顷了。如果人口再无节制地增长下去，我国人多地少的局面将会越来越严峻。

⑤随着人口的迅速增长和生产技术的不断进步，人类对环境的冲击和压力也越来越大，特别是毁林开荒、开垦草原、围湖造田等措施，改变了生态系统的结构和功能，使生态平衡遭到了破坏，导致严重的水土流失和气候失调，洪水、旱涝等自然灾害也频繁发生。［甲］我国历史上也有这样的例子。［乙］黄土高原原来有茫茫的林海和无边的草原，非常适合人类生活。但由于人口过于集中、长期掠夺式的开发和战争等原因，破坏了植被，引起了严重的水土流失和生态平衡失调。［丙］如今，黄土高原的许多地方已经变成了沟壑纵横的荒山秃岭。［丁］可见，人口过度增长是导致生态平衡失调的重要原因。

⑥为了人类世世代代有一个美好的生存环境，人类必须控制人口的增长，做到有计划地发展。

When was the last time your family sat down together to have a dinner?

The speed at which we live today no longer allows for slow eating habits. Most people work long hours. There is lots of fast food and eating out is now on the increase. Often, food is eaten in front of the television in silence, or a child eats alone in front of the computer.

When I was a child, every evening around the same time, one of the children would be asked to set the table, and then we'd go and wash our hands: before the meal. This was the time of day when we would talk about our day at school. But now things have changed a lot.

A family environment plays an important role for children in learning to communicate with others and understanding table manners, such as waiting for others to finish before leaving the table and not speaking with a mouth full of food. Parents’ likes and dislikes of a certain food will also influence a child's own likes and dislikes. Studies have shown that children who often eat with their families have better results at school than children who eat with their families less than twice a week.

Regular meal times give children the chance to discuss their problems with family members. They can also learn to respect others around the table. Talking to your children over dinner is the best way of having their-trust. Children learn good eating habits from their parents at a very young age. Family meals are important. Prepare them for your children.
