Questions 1-8. Read the text carefully then answer the following questions.

Tourism will always have an impact on the places that people visit. Sometimes the impact is positive, but most of the time it is negative. For example, a large number of visitors in one destination can cause bad effects on the environment. The question is, how can we minimize the problems while still allowing people to travel and visit places?

The main goal of eco-tourism is to limit the bad impact of tourism on the environment and local people. The task is to encourage tourists to think about what they do when they visit an area. There are many key points. Tourists should not litter, should stay on the paths, should not interfere with wildlife and should respect local customs and traditions. Some people consider eco- tourism to be a double-edged sword that has both advantages and disadvantages. They argue that tourism requires infrastructure such as roads and airports. The more tourists visit a destination, the more of infrastructure is necessary so that the tourists can stay and benefit the local community financially. However, it’s difficult to avoid damaging the environment and develop local tourism at the same time. Eco-tourism can only develop in the right way if governments can deal with the negative effects and make sure that modern improvements benefit the local people and environment, not just the tourists.

In 2002, the United Nations General Assembly celebrated the International Year of Eco-tourism (IYE) to evaluate global eco-tourism experiences. More and more people have chosen eco- holidays over the past 20 years. Eco-tourism truly plays a key role in the tourism industry in many countries like Kenya, Costa Rica, Ecuador and Nepal.

Questions 9-15. Read the text carefully then answer the following questions.

One threat to South East Asia’s biodiversity is the illegal wildlife trade. Worth approximately US$20 billion annually, it’s the fourth-biggest illegal trade in the world.

In Southeast Asia, hunting represents the greatest threat to the future survival of many species, with few native mammals of over 2kg surviving outside protected areas. Hunting represents a threat to all species, with high-value species sought and traded by criminal groups and smaller species traded for medicine, food or sport.

Trade in wildlife in Asia can be grouped into three main types: for medicinal purposes, for status (either in wildlife restaurants or as ornaments) or for the pet, zoo and aquarium trades (principally birds and reptiles).

Traditional medicine in Viet Nam and China represents a threat to a wide variety of species, but most notably the pangolin, which is the most trafficked animal on the planet. Sadly, the use of endangered species in medicine shows little sign of decrease. Whereas celebrities have campaigned for species that are targeted for status and ornamentation, such as elephant ivory, many other animals and plants have failed to get the attention needed to prevent over-exploitation. And a number are now facing extinction.

The pet and zoo trade in wildlife, especially for reptiles and birds, have recently received attention, as many species formerly thought to be captive-bred are now known to be wild-caught. They have suffered serious population declines as a result of exploitation for trade.

Questions 16-20. Read the text carefully then answer the following questions.

Conservation is the sensible use and protection of natural resources including plants, animals, mineral deposits, soils, clean water, clean air, and fossil fuels such as coal, petroleum, and natural gas to ensure an adequate supply for future generations.

Natural resources are grouped into two categories, renewable and nonrenewable. A renewable resource is one that may be replaced over time by natural processes, such as fish populations or natural vegetation, or is inexhaustible, such as solar energy. The goal of renewable resource conservation is to ensure that such resources are not consumed faster than they are replaced.

Nonrenewable resources are those in limited supply that cannot be replaced or can be replaced only over extremely long periods of time. Nonrenewable resources include fossil fuels and mineral deposits, such as iron ore and gold ore. Conservation activities for nonrenewable resources focus on maintaining an adequate supply of these resources well into the future.
