Ecoturism

1) Eco-tourism:  
The Ecotourism Society defines it as "responsible travel to natural areas which conserves the environment and improves the welfare of the local people".  Awalk through the rainforest is not eco-tourism unless that particular walk somehow benefits that environment and the people who live there.  A rafting trip is only eco-tourism if itraises awareness and funds to help protect the watershed.  A loose interpretation of this definition allows many companies to promote themselves as something that they are not.  Iftrue eco-tourism is important to you, ask plenty of questions to determine if your trip will help "conserve and improve" the places you visit.

2) Environmentally risky.
  Eco-tourism may sound benign, but one of its most serious impacts is the expropriation of`virgin' territories - national parks, wildlife parks and other wilderness areas - which arepackaged for eco-tourists as the green option. Eco-tourism is highly consumer-centered, catering mostly to urbanised societies and the new middle-class `alternative lifestyles'.Searching for `untouched' places `off the beaten track' of mass tourism, travellers have already opened up many new destinations.
   Mega-resorts, including luxury hotels,condominiums, shopping centres and golf course, are increasingly established in nature reserves in the name of eco-tourism - in many cases protested as `eco-terrorism'. Such projects buildcompletely artificial landscapes, tending to irretrievably wipe out plant and wildlife species - even entire eco-systems.

Yes, because ecotourism conserves the environmentand helps the earth, ecotourism can be a good idea for the environment but some people do this thing with other benefits only for money and it can be a danger for the environment
