Ecotourism is often regarded as a form of nature-based tourism and has become an important alternative source of tourists. It is broadly defined as low __________ travel to endangered and often undisturbed locations. It is different from traditional tourism because it allows the traveler to become educated about the areas. And it often provides funds for conservation and __________ the economic development of places that are frequently poverty-stricken.

Ecotourism and other forms of sustainable travel have their __________ with the environmental movement of the 1970s. Ecotourism itself did not become prevalent (流行的) as a travel concept until the late 1980s. During that time, increasing environmental awareness and a desire to travel to natural locations as __________ to built up tourist locations made ecotourism desirable.

Since then, several different organizations specializing in ecotourism have developed and many different people have become experts on it. Martha D. Honey, PhD, a co-founder of the Center for Responsible Tourism, __________, is just one of many ecotourism experts.

Opportunities for ecotourism exist in many different locations worldwide and its activities can vary __________.

Madagascar, for instance, is famous for its ecotourist activity as it is a biodiversity hotspot, but also has a high priority for environmental conservation and is devoted to reducing poverty. Conservation International says that 80% of the country's animals and 90% of its plants are __________ to the island. Madagascar's lemurs (马达加斯加狐猴) are just one of many __________ that people visit the island to see.

Because the island's government is __________ to conservation, ecotourism is allowed in small numbers because education and funds from the travel will make it easier in the future. __________, this tourist revenue also aids in reducing the country's poverty.

Despite the popularity of ecotourism in the above-mentioned examples, there are several __________ of ecotourism as well. The first of these is that there is no one definition of the term so it is difficult to know which trips are __________ considered ecotourism.

Critics of ecotourism also cite that increased tourism to __________ areas or ecosystems without proper planning and management can actually harm the ecosystem and its species because the infrastructure needed to sustain tourism such as roads can contribute to environmental degradation (恶化).

Ecotourism is also said by critics to have a negative impact on __________ communities because the arrival of foreign visitors and wealth can shift political and economic conditions and sometimes make the area __________ tourism instead of the domestic economic practices.

Regardless of these criticisms though, ecotourism and tourism, in general, are increasing in popularity all over the globe and tourism plays a large role in many worldwide economies.
