Ecotourism is beneficial. When people pay to go places that show off the beauty of this planet and they see it with their very own eyes, they will be more prone to support things that protect the world's natural beauty. They will want to throw their support behind causes that benefit the environment.
When done properly, ecotourism promotes local economies and the environment. Whale watching, Amazon rain forest floats, trips to the Galapagos Islands and mountain hikes all promote environmental awareness and local guides. Ecotourism is a great way to promote caring for the Earth in respectable ways while spending money wisely and rewarding those who take care of our planet.
