So why is this huge increase in population taking place？ It is really due to the spread of the knowledge and practice of what is becoming known as "Death Control". You have no doubt heard of the term "Birth Control". "Death Control" is something rather different. It recognizes the work of the doctors and scientists who now keep alive people who, not very long ago, would have died of a variety of then incurable diseases. Through a wide variety of technological innovations that include farming methods and the control of deadly diseases, we have found ways to reduce the rate at which we die. However, this success is the very cause of the greatest threat to mankind.
If we examine the amount of land available for this ever-increasing population, we begin to see the problem. If everyone on the planet had an equal share of land, we would each have about 50,000 square meters. This figure seems to be quite encouraging until we examine the amount of usable land we actually have. More than three-fifths of the world's land cannot produce food.
Obviously, with so little land to support us, we should be taking great care not to reduce it further. But we are not! Instead, we are consuming its "capital" — its nonrenewable fossil fuels and other mineral deposits that took millions of years to form. but which are now being destroyed in decades. We are also doing the same with other vital resources not usually thought of as being nonrenewable such as fertile soils, groundwater and the millions of other species that share the earth with us.
It is a very common belief that the problems of the population explosion are caused mainly by poor people living in poor countries who do not know enough to limit their reproduction. This is not true. The actual number of people in an area is not as important as the effect they have on nature. Developing countries do have an effect on their environment, but it is the populations of richer countries that have a far greater impact on the earth as a whole.
According to the article, what contributes to the population increase？
A．Birth explosion.
B．Birth Control.
C．Technological innovations.
D．Death Control.

It can be really frustrating (使人沮丧的) for an overweight person to go to a gym and work out with a positive attitude. All one has to do is walk by almost any nice gym and notice all the healthy, sweating, “skinny ” members. Sometimes they stare at those of us who are, well, zaftig . It is easy to see the judgment behind their eyes. Who wants to put up with that？ Many people are self-conscious of their bodies and feel isolated when joining workout classes of while exercising, especially if they are larger than most of the others in the group. Now the fitness industry is finally paying attention. Popular gyms are catering (迎合) to overweight and weight conscious customers by dedicating areas where the “skinny ” people are not allowed. There are even gyms or programs that require members to be at least 50 pounds overweight to participate. Trainers recommend functional fitness as a practical goal, rather than six-pack abs(六块 腹肌). (79)They often use text messages to stay in touch with customers. Often at these specialized gyms, the trainers are overweight themselves, or working on their own weight goals, and this can help those people with anxiety caused by poor body image. The equipment has been designed for use by larger people. Wider seats, more cushioning, no mirrors, and tinted (有色的) windows for privacy, are all important changes. (80)Hopefully these types of gyms will successfully grow in numbers in the future. The idea is a very simple and potentially popular one. If it helps those of us who are bigger exercise more and improve our fitness level, it ’s a step in the right direction. The word zaftig in Paragraph 1 is closest in meaning to _______.
A.fat
B.healthy
C.friendly
D.polite
