Here's a nice hour long video by the Democratic Socialists of America organisation where they go into the inhumane sanctions on Cuba.

As the description of the video reads: Description US sanctions have besieged socialist Cuba for over six decades. While 2018 UN estimates have calculated a direct loss of $130b in trade alone, the toll of the embargo on Cuban life can hardly be quantified. Most recently, US economic interference has stymied Cuba's response to the COVID-19 pandemic, resulting in deteriorating conditions on the island. With escalating tensions coming from the Biden administration against the Cuban people, solidarity is more timely than ever.

I also recommend We Are Cuba! By Helen Yaffe. A book which explores the changes adopted by Cuba after the collapse of the Soviet Union. As a review reads: "(...) energy revolution, and medical internationalism alongside recent economic reforms, Yaffe shows why the revolution will continue post-Castro."

Best of luck with your presentation comrade! We all stand in solidarity with you.
