How true is this statement? What can tourists do to reduse the harmful effects tourism on local cultures and enviroment?

Task 2 In reality, tourism contribute one of the huge nature problems of a country. It is because that they do not have to ipmrove the surrounding. The main reason is because the tourist destination are poor of policies and there is no rule and offical penalty for the infraction to obey so same tourists tend to ignore the metter of enviroment impacts. For example, tourists in a beach who litterad rubbish unable to get any sanction but they are free to go to anywhere else. I think to decrease the impact every tourists would a country the goverment with give introduction of a country to every visitors it means tourism regards to obey the country rules and penalities so tourust tend much more aware during travell with this way the purpose of clean nature obtain convenience. In conclusion, the increasing of tourist seem a impact of the nature problems but tourists expend as an income in the same occasion.
