Read the following passage carefully and answer the questions given below.
Since the word has become industrialized, there has been an increase in the number of animal species that have either become extinct or are nearing extinction. Bengal tigers, for instance, which once roamed in the jungles in vast numbers, now number only 2,300 and by the year 2025, their population is estimated to go down to zero. What is alarming about the case of Bengal tiger is that this extinction would have been caused almost entirely by poachers who according to some sources, are not interested in material gain but in personal gratification. This is an example of the callousness that is part of what is causing the problem of well as other endangered species, are a valuable part of the world’s ecosystem. International laws protecting these animals must be enacted to ensure their survival and the survival of our planet. Countries around the world have begun to deal with this problem in various ways. Some countries, in order to circumvent the problem, have allocated large amounts o land to animal reserves. They then charge an admission fee to help defray the costs of maintaining the parks and often must also depend on world organizations for support. When they get the money, they can invest in equipment and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of products made from endangered species. This seems fairly effective, but it will not by itself prevent animals from being hunted and killed.
