Beginning and observation

Chemical reactions happen in all living things, on the ground, in the air, at home, everywhere: from breathing to fuel combustion. Chemical reactions, both the natural and those produced by human beings, have changed the direction of humankind. Some have also changed the characteristics of the planet and living things.

Human beings do several things that produce chemical reactions unknowingly, either due to ignorance or because changes are instantaneous. Their effects can have consequences for society. That is why it is important to know about reactions and what they produce, so we can be aware of their impact on the environment and bring about change to reduce their impact.
