Fish and aquatic creatures are beautiful jewels of nature. The guardians of the water world reflecting the state of our direct environment and the water quality. It is impossible for them to survive in polluted conditions with a chemical overload. And if our aquatic friends cannot survive these conditions, we should take heed as well, as we all need healthy water to survive!
Perhaps only a few of us can grasp, (if you follow a hobby or career dependent on water quality - be it an aquaculture farmer, breeder, environmentalist or research and developer) but once you have entered the world of aquatic creatures, you will soon get to know the fact that there is so much more to water quality than that which meets the eye. From microscopic creatures to photosynthetic balances, key nutrients, minerals, the nitrogen cycle, pH levels and external factors like atmospheric pollution, rain, temperatures and a whole bunch more are all key ingredients that influence water quality.
Mix this with the harmful chemicals used in households, farming practices, industries and in the water purification plants to see that any unbalance not only changes the appearance of water but also negatively impacts the dissolved oxygen levels and the water quality and in return effects our aquatic friends. Besides this, we are currently facing challenges of a chemical overload in natural water resources that results in hypoxia, toxic algae blooms, Cyanobacteria (blue green algae) - killing our fish and aquatic life.
Medicines like antidepressants are finding their way into lakes and rivers changing the natural breeding and behavioral patterns of fish and aquatic life. A study completed by scientists found this drug in the brains in more than ten different species of fish in the Great Lake regions. Not only does it impact the biodiversity of the fish but scientist from the University of Buffalo say that it can cause harmful changes to the behavior of the fish resulting in a lethargic state with not desire to eat or breed. The bird and wildlife is exposed to the dangers of this drug as well.
Harmful chemicals and drugs like these find their way into our natural water resources from water purification plants that is designed to remove waste and kill pathogens. It is impossible to remove all the traces of chemicals and drugs.
Think about it for a moment; every time we use harmful chemicals at work or at home, in our aquariums, ponds or aquaculture farming, it will find its way back into our rivers, lakes and estuaries! Now, that is a huge responsibility! It means (lets spell it out) that we directly influence our rivers, lakes and estuaries. You don't need to be a scientist to become aware of the state of our earth's water - read, search and become aware of the impact that our choices have on nature!
Preserve our natural resources for the sake of human and animal existence and to secure a future for our children.
