Write about selena's death or how different events are celebrated such as cinco  de mayo. those are some example for starters

Hi jordan! , i hope you are well i knew you want to travel and i decided to you through this letter where i compare peruvian life with the american in some aspects, so i can start by saying that both countries have a great diversity, from their geography to the demographic composition; it is impossible to speak of a unique feature in this scenario of geographical, racial, ethnic and cultural wealth. for example, in peru there is a population of 31,481,000 people, and it has a moderate population density, 24 inhabitants per km2, of which only 43,000 are latin american immigrants, which is much less than in the usa. also in the united states, the flow of immigrants, who come from the most remote regions of the planet or from the bordering nations, has been continuous and constant for 150 years. for example, in 2013 there were around 41.3 million immigrants in the united states, which represented 13% of the total population.something important to note for this is the difference between the transport of both countries, in peru even though there is only the transport of the plane and the bus, it has the second best transport infrastructure in south america unlike the usa, which has all the means in operation. in this part you can also mention the sport, since it is something very important. the evolution of sport in peru, as an underdeveloped and dependent country, is simply the expression of the history of sport on a world scale, while the usa, through the educational system, keeps sport low, the use of promotion systems is infrequent and relegation of teams in the championship pyramid that is the norm in europe and south america.diversity is also reflected in geography and climate. there are landscapes as diverse as alaska, the arizona desert, the niagara falls on the canadian border, the beaches of california, the corn fields of the midwest or the most cosmopolitan cities on the planet. while in peru the division into coast, mountains and jungle offers us a cultural variety. at the gastronomic level, its diet is based on gorge on fast food or precooked dishes that are prepared at home in a matter of minutes. unlike the peruvian cuisine that is one of the most varied in the world.peruvian dishes are prepared with products that have been used since pre-columbian times, such as potatoes, corn, chili, seafood and fish, to which are added beef, pork and chicken.i think that with that i have said everything i think and i know of both countries, i hope it serves as a reference.sincerely,
