Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase of world population in countries continues at the present rate, there may be much greater harm to human beings. Some scientists speak of the increase in numbers of people as “population pollution.”
About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2,000. If the population continues to grow at the same rate, there will be 25 billion in the world a hundred years from now.
Man has been using the earth’s resources more and more rapidly over the past years. Some of them are almost used up. Now many people believe that man’s greatest problem is how to control the growth of the population. The material supplies in the world will be far from enough to support the human population, in time to come, if the present rate of increase continues. Already there is overcrowding in many cities and starvation in some countries. Should man’s population keep on growing so rapidly as before? Many people believe that human survival in the future depends on the answer to this question.

Macao is only forty miles from Hong Kong and it is easy to reach. You can get there by sea. It is an interesting place and it had a long history. Macao is part of China and most people living there are Chinese.
The first Europeans to go to Macao came from Portugal. More than four hundred years ago the Portuguese went there to trade with China. Some settled and made their homes there. They built strong forts to guard the city and the harbor. They also built churches, schools, hospitals and other places. Slowly the city grew. People from many countries came to live and work in Macao.
Today many people visit Macao. Some only go there to watch dog-racing or motor-racing or to gamble with their money. But Macao is a quiet and peaceful place. It is pleasant just to walk around and look at old buildings and forts. You feel you are back in the old days. Of course, some of the buildings are now in ruins. The Church of St. Paul has only the front wall with many steps leading up to it. But it is still interesting to see.
When you are hot and tired, there are small cool gardens to rest in. When you are hungry, there are good restaurants with many kinds of food. Nearby there are some islands, which are also nice and are easy to get to. There is certainly a lot to do in Macao.

Man’s best friend could be one of the environment’s worst enemies, according to a new study that says that your pet dog’s carbon pawprint(碳足迹) is more than double that of a sports car.
Yet this point of view, made by New Zealanders Robert and Brenda Vale, has angered pet owners who feel they are being picked out as troublemakers.
The Vales, researchers in sustainable(可持续的) living, looked at popular brands of pet food and calculated that a medium-sized dog eats about 164 kilos of meat and 95 kilos of grain a year.
Combining that with the energy needed to produce that food, it means a medium-sized dog has an annual footprint of 0.84 hectares(公顷), about twice the 0.41 hectares required by a sports car driving 10,000 kilometers a year, including energy to build the car.
“Owning a dog really is quite an extravagance(奢侈), mainly because of the carbon footprint of mean. Other animals aren’t better for the environment,” the Vales say.
Cats have an eco-footprint of about 0.15 hectares a year, while two hamsters(仓鼠) are the same as a television and even the goldfish burns energy equal to two cellphones.
However, Reha Huttin, president of France’s 30 Million Friends animal rights foundation says pets are too important to human life to be got rid of.
“Everyone should work out their own environmental effect,” Huttin argude. “I should be allowed to say that I walk instead of using my car and that I don’t eat meat, so why souldn’t I be allowed to have a little cat to reduce my loneliness?”
The Vales give some solutions to reduce pets’ environmental effect, including reducing pets’ meat intake. But they said that, as with buying a car ,humans should take the environmental effect of their future compainon into account.

Imagine your body is like the house you live in．Every day, your family creates rubbish．The rubbish builds up until it is put out for the weekly garbage collection．

This is a simple description of what happens to your body when your kidneys （肾脏）don't work efficiently．Your body is nol thoroughly emptied of waste products．Other areas of the bodv such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins．
It's not uncommon for people to lose up to 90% of their kidney function before deveoping any symptoms．There may be no warning signs. This makes early detection （诊查）difficult．
Kidney's main job is to remote toxins（毒素） and unwanted water from our blood．Every day our kidneys clean an average of 200 litres of blood．Kidney failure may be a gradual and silent process, going unnoticed because there is no apparent pain．
Research shows that more than 35% of the patients requiring dialysis （透析）do not see a kidney specialist before they have to do so．Some risk factors for kidney disease such as age and genetic make up are out of our control; however, some changes in lifestyle may help prevent kidney damage．Two major risk factors for kidney disease, diabetes （糖尿病）and high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential risk factors for the kidney disease．

When I was an education official in Palo Alto, California．Polly Tyner, the president of our school board, wrote a letter that was printed in the Palo Alto Times．Polly's son, Jim．had great difficulty in school．He was classified as educationally disabled and required a great deal of patience on the part of his parents and teachers．But Jim was a happy kid with a great smile that lit up the room．His parents acknowledged his academic difficulties, but always tried to help him see his strengths so that he could walk with pride．Shortly after Jim finished high school, he was killed in a motorcycle accident．After his death, his mother submitted（提交）this letter to the newspaper．
Today we buried our 20-year-old son. He was killed instantly in a motorcycle accident on Friday night. How I wish I had known when I talked to him last that it would be the last time. If I had only known I would have said, “Jim, I love you and I’m very proud of you.”
I would have taken the time to count the many blessings he brought to the lives of the many who loved him. I would have taken the time to appreciate his beautiful smile, the sound of his laughter, his genuine love of people.
When you put all the good qualities on the scale and try to balance all the irritating phenomena such as the radio which was always too loud, the haircut that wasn’t to our liking, the dirty socks under the bed, etc., your angry feelings won’t amount to much.
I won’t get another chance to tell my son all that I would have wanted him to hear, but, other parents, you do have a chance. Tell your young people what you would want them to hear if you knew it would be your last conversation. The last time I talked to Jim was the day he died. He called me to say, “Hi, Mom! I just called to say I love you. Got to go to work. Bye.” He gave me something to treasure forever.
If there is any purpose at all for Jim’s death, maybe it is to make others appreciate more of life and to have people, especially family members, take the time to let each other know just how much we care.
