The correct answer to this open question is the following.
The two intervention programs that the government could put into place to encourage tourists, not to litter would be the following.
1.- Advertising campaign in the United States airports. As soon as tourists arrive in the United States, there would be TV screens and signs in every airport, informing that littering is strictly prohibited in the United States.
2.- US embassies abroad. A similar campaign should be implemented in the many US embassies around the world. So when people solicit their visas to enter the United States, they could be informed that there is strict legislation in the US regarding littering.
This way tourist will be informed previous their arrival to the country.
These recommendations will help the illegal dumping situation for tourists in that they will be very aware that there will be serious consequences if they are caught littering.

I think this should be for your own words but this is what I think you could put in your own words
1. To know that that obstacle will only last so long
2. You have to keep pushing to chase your dreams/goals
3. Take time to focus on yourself and your goals/dreams and how you can achieve it little by little
4. Avoid things that are causing you to doubt the ability to pursue your goal/dream
5. Remind yourself that it’s not always going to be easy but you will get through it
Hope this helps:)
