Not much.
They're fairly slow, and with little to no sideways control it's hard to aim for a certain place to land.
Hot air balloons do not directly produce air pollution because they are powered by propane burners that combust the gas cleanly. However, the transportation and support vehicles used to operate hot air balloons can contribute to air pollution through emissions from their engines.
Hot air balloons are now mostly used for leisure
The most obvious are being used every day. Air transportation includes: Airplanes, Helicopters, Hot Air Balloons, Blimps, Rockets, Kites, Parachutes and Birds.
Ballooning is a form of transportation, men have gone around the globe in balloons. The problem is that balloons lack control and it is hard to plan with all certainty where a trip will culminate. Most hot air balloons are used for leisure and exhibitions.
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
Hot air ships, also known as hot air balloons, were successful in terms of demonstrating manned flight. The first successful hot air balloon flight was achieved by the Montgolfier brothers in 1783. However, hot air balloons are limited in terms of speed, distance, and control compared to other forms of air transportation.
Yes, it is possible to fly with balloons by using a hot air balloon or helium balloons, but flying with small party balloons is not feasible for human transportation.

The first use of hot air balloons was in the American Civil War for surveillance of troop movements.
Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
