1)Effects on humans:
1.Bacteria become resistant to antibiotics and are no longer affected by them.
2.Residues of antibiotics can remain in animal products consumed by humans.
3.Dangerous and highly resistant bacteria can emerge and spread to humans.
4.Antibiotics can also kill beneficial bacteria that are important for human health.
2)Effects on the environment and biodiversity:
1.Pollution of water and soil due to antibiotic residues.When animals take antibiotics, they do not use all of the medication. The remaining part is excreted in their waste.
This waste then reaches the soil or is washed into water sources.
2.Destruction of useful soil bacteria, which reduces soil fertility and affects plant growth.Antibiotics do not distinguish between harmful bacteria and beneficial bacteria.
3.Antibiotics can harm other animals and may cause long-term toxic effects.
So,when water and soil are contaminated, plants and animals are affected, leading to an imbalance in biodiversity.
