Because they let us get around a lot eg like in our cars.But some reactions cause a lot of pollution so you cant use them to often. but other reactions are good!
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
It allows us to see.

Two types of displacement reactions are known:- single displacement- double displacement
Fuels are burned to release energy in the form of heat, which can be used to generate electricity, power vehicles, and heat spaces. These reactions are useful because they are efficient at converting chemical energy into thermal energy, providing power for various applications in our daily lives.
Exothermic and Endothermic reactions are part of the natural universe. Without it, temperatures would remain stagnate. In light of technology harnessing these reactions, they provide us with a number of useful abilities. They are useful in that we use these reactions to cook our food, heat our water, cool our airs and refrigerate our storages, to name a few.
