Two household chemical reactions that can be dangerous:
Bleach and ammonia. These two common cleaning agents produce toxic products when combined. They react in a multiple-pathway reaction to produce chloromine, hydrazine, and pure chlorine gas. Make sure you have lots of ventilation if you combine these two. Also, liquid drain cleaner and aluminum foil. This produces copious amounts of hydrogen gas, which in a sealed container, can build up high pressure. Hydrogen is very flammable. Both the aforementioned reactions are vigorously exothermic as well, which means they get hot!
If the earth gets warmed up, the ice at the poles will melt causing increase in sea level and floods.
Acid RainsAcid Rains kill plant life. If the harmful acidic water from the rain seeps into the soil and into the plant, the acid can cause death to the plant.

useful photosynthesis cooking food process of digestion harmful pollution rusting taking highly acidic food
NOT ANSWER!! SORRY I HAD MISTAKEN, QUESTION WAS: What chemical change can producers do that makes food for All of us?
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 is hrmful because the erosdion causes it o change.

Chemical Hazard is the danger caused by chemicals to the environment and people. A chemical hazard arises from contamination with harmful or potentially harmful chemicals.

If you cut an apple and keep, the colour changes to brown. This is physical change. Apple has iron (in the form of ferrous salts). The colour is due to the formation of harmful ferric compounds and this is a chemical change (conversion of ferrous to ferric).
