Dear Sir,
I wrote this email to talk about today's predictions of a city of the future. It is still our familiar city, but in the future, the city is no longer smog, because it has been equipped with smart air purifiers installed on street lights and traffic lights. In addition, air purifiers can be installed in buildings, vehicles, or in the homes of all residents, helping to ensure a clean and fresh air system for everyone. Respiratory diseases will be reduced completely, girls do not need to worry about the risk of dry skin anymore. The city of the future will be smog-free thanks to air purifiers and steam-filled balls ready to cool the city: "The future is a city with no dust, no traffic jams, no beggars, not bad. social distress and no more poor people "An ambulance in this city is also very interesting. These are modern, compact, driverless fast-flying vehicles capable of self-care and rescue of patients in the most challenging terrain. We also do not need to worry about our home when going away in the future. We can shrink our smart home like a backpack and carry it up the mountain or into the sea. Hey, then the hotels will be empty? "The future is when our house can be as small as a backpack and take it with us wherever we go. " Housing is also not a headache for people. Our smart home can have only one room and with the push of a button, we can switch the function and design of a room from the bedroom to the living room or the kitchen. The house also has a self-cleaning and cleaning function, deodorizing, and garbage collection with just one press of a button. 

1. Essay on Causes and Affects of Global Warming:

Global warming is the gradual increase in the average temperature of the Earth's atmosphere and oceans. The main cause of this phenomenon is the burning of fossil fuels, which releases large amounts of greenhouse gases, such as carbon dioxide and methane, into the atmosphere. These gases trap heat from the sun, causing the Earth's temperature to rise.

The effects of global warming are far-reaching and potentially devastating. One of the most significant consequences is the rising sea level, which can flood coastal areas and displace millions of people. Global warming is also causing extreme weather events, such as heatwaves, droughts, and hurricanes, to become more frequent and severe. Additionally, it has a significant impact on biodiversity, with many plant and animal species becoming endangered or extinct due to changes in temperature and rainfall patterns.
