Introduction
（導入）
Although eco-tourism might have some downsides, the advantages far outweigh the disadvantages.
First body paragraph （メリットを説明）
The main advantage is that we can provide financial support for conservation. According to a survey, for example, the quality of life among Costa Ricans living in a protected area has improved by 16%, thanks to eco-tourism. There are also many other areas enjoying eco-tourism revenue.
Second body paragraph （デメリットを説明）
On the other hand, there are some disadvantages to eco-tourism, too. It can change wildlife behavior. For example, in Kenya, tourist jeeps scare away lions so they cannot get to their food. As a result, they have to change their hunting habits.
Conclusion （結論）
In conclusion, despite the challenges, I believe that the advantages of eco-tourism are far greater than the disadvantages.
