Question

A speech on topic 'green crackers'

Answer 1

Green crackers are those crackers which do not contain harmful chemicals that would cause air pollution. They are environmentally friendly. So, we can say that green crackers are less harmful as compared to conventional firecrackers and less pollution emission will result in reduced air pollution. That is why it is decided to develop eco-friendly firecrackers and fireworks.

In green crackers the commonly used polluting chemicals like aluminium, barium, potassium nitrate and carbon have either been removed or sharply reduced to slow down the emissions by 15 to 30%.
