Once the last tree is cut and the last river poisoned, you will find you cannot eat your money - I think that will happen in the future if humans won't start to think what are they doing , how they are ruin world around themselves. If it happen, humans will realize that they need it all back but maybe it will be to late.
In our country everywhere where you look can see the dust. Maybe government should left more dustbin and make an information about this problem in newspapers and TV. Also in our country are acid rain and air pullution. I think the couses of that are industrie, too much cars and other stuffs like that.
To be an aco-friendly tourist person have to use things that are friendly for nature. Also tourist have to clean up everything what they left behind.
