Answer:
Fireworks on New Year’s Eve. Some of us love them, some of us aren’t so keen (especially our four legged friends). As you may have noticed, the large fireworks displays are less and less frequent and more and more expensive, and much of this is to do with the pollution they create.
Fireworks Fireworks cause extensive air pollution in a short amount of time, leaving metal particles, dangerous toxins, harmful chemicals and smoke in the air for hours and days. Some of the toxins never fully decompose or disintegrate, but rather hang around in the environment, poisoning all they come into contact with. Exposure to fine particles, like those found in smoke and haze, is linked to negative health implications, such as coughing, wheezing, shortness of breath, asthma attacks and even heart attacks, according to the EPA. People at greatest risk for problems are those with heart or lung disease, older adults and children.
In a fireworks display, those particles that fall to the ground (chemicals and actual physical pieces of waste) often contain propellant chemicals and colorants, which find their way into the soil and our water systems. Many of the raw materials used to create fireworks are mined from mountains, a destructive process that cuts down forests and destroys wildlife habitats. Leftover rock is discarded into valleys, blocking and polluting flowing streams.

Answer:
A firecracker is a small explosive device primarily designed to produce a large amount of noise, especially in the form of a loud bang, usually for celebration or entertainment; any visual effect is incidental to this goal. They have fuses, and are wrapped in a heavy paper casing to contain the explosive compound. Firecrackers, along with fireworks, originated in China.The predecessor of the firecracker was a type of heated bamboo, used as early as 200 BC, that exploded when heated continuously. The Chinese name for firecrackers, literally means "exploding bamboo". After the invention of gunpowder, gunpowder firecrackers had a shape that resembled bamboo and produced a similar sound, so the name "exploding bamboo" was retained. In traditional Chinese culture, firecrackers were used to scare off enemies or evil spirits.Firecrackers are generally made of cardboard or plastic, with flash powder, cordite, smokeless powder, or black powder as the propellant. This is not always the case, however. Anything from match heads to kerosene and lighter fluid has been used successfully in making firecrackers. The key to loud firecrackers, however, although in part lying in the propellant substance, is pressure. The entire firecracker must be very tightly packed in order for it to work best. Flash powder, however, does not need to be packed tightly, and should not be.James Dyer Ball, in his book Things Chinese, has a detailed description about the process and material used for making firecrackers at the end of the 19th century. At that time, firecrackers were made by female and child workers, using straw paper to make the body of the firecracker, while the fuse was made of bamboo paper imported from Japan, then stiffened with buckwheat paste. The bamboo paper was cut into strips of 14 inches (360 mm) long and 1⁄3 inch (8.5 mm) wide, laid on a table; a string of gunpowder was placed at the center with a hollow tube, then twisted up to make a piece of fuse. The firecracker tubes were made from pieces of straw paper wrapped around iron rods of various diameters and then tightened with a special tool. 200 to 300 firecrackers were tied up in a bunch, then red clay was spread at the bottom of the bunch and forced into each end of the firecracker with a punch; gunpowder was poured in, then the other end was sealed with an awl by turning the tube inward, and a fuse inserted.Firecrackers are commonly used in celebration of holidays or festivals, such as Halloween, Independence Day (also known as the Fourth of July) in the United States, Diwali in India, Eid al-Fitr in Southeast Asia, Tihar in Nepal, Day of Ashura in Morocco, Guy Fawkes Night or Bonfire Night in the United Kingdom, Halloween in Ireland, Bastille Day in France, Spanish Fallas, in almost every cultural festival of Sri Lanka (e.g. Sri Lankan New Year), New Year's Eve and New Year's Day, and in the celebration of Chinese New Year by Chinese communities around the world. In Wales the slang term for a firecracker, typically used on Guy Fawkes Night, is a "jacky-jumper".The use of firecrackers, although a traditional part of the celebration, has over the years led to many injuries and deaths. There have been incidents every year of users being blinded, losing body parts, or suffering other injuries, especially during festivities that customarily involve firecrackers such as Chinese New Year season. Hence, many governments and authorities have enacted laws completely banning the sale or use of firecrackers, or banning the use of firecrackers in the street, primarily because of safety or environmental reasons. These rules also require a permit from the local government, as well as any relevant local bodies such as maritime or aviation authorities (as relevant to the types of fireworks being used) and hospitals, schools, etc. within a certain range.
