A concrete noun employs the senses of sight, touch, hear, taste, and smell. So: Bible, lamb, and tooth
Global warming
Rising global temperatures caused by CO2 emissions heat the water, reducing its oxygen content.
Deforestation
Felling forests can exhaust water resources and generate organic residue which becomes a breeding ground for harmful bacteria.
Industry, agriculture and livestock farming
Chemical dumping from these sectors is one of the main causes of eutrophication of water.
Rubbish and faecal water dumping
The UN says that more than 80% of the world's sewage finds its way into seas and rivers untreated.
Maritime traffic
Much of the plastic pollution in the ocean comes from fishing boats, tankers and cargo shipping.
Fuel spillages
The transportation and storage of oil and its derivatives is subject to leakage that pollutes our water resources.
EFFECTS OF WATER POLLUTION
Deteriorating water quality is damaging the environment, health conditions and the global economy. The president of the World Bank, David Malpass, warns of the economic impact: "Deteriorating water quality is stalling economic growth and exacerbating poverty in many countries". The explanation is that, when biological oxygen demand — the indicator that measures the organic pollution found in water — exceeds a certain threshold, the growth in the Gross Domestic Product (GDP) of the regions within the associated water basins falls by a third. In addition, here are some of the other consequences:
Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —.
Contamination of the food chain. Fishing in polluted waters and the use of waste water for livestock farming and agriculture can introduce toxins into foods which are harmful to our health when eaten.
Lack of potable water. The UN says that billions of people around the world have no access to clean water to drink or sanitation, particularly in rural areas.
Disease. The WHO estimates that about 2 billion people have no option but to drink water contaminated by excrement, exposing them to diseases such as cholera, hepatitis A and dysentery.
Infant mortality. According to the UN, diarrhoeal diseases linked to lack of hygiene cause the death of about 1,000 children a day worldwide.
Virus is actually just a piece or strand of genetic information usually DNA or RNA which can be single or double stranded.
Viruses are everywhere from our surroundings to the very food we eat. We ingest, inhale and talk in millions of viruses every second. Pretty much all life on Earth has some kind of virus designed specifically to infect in including bacteria and even other viruses. Viruses are tiny very tiny you can visibly see them if fact they are so small that if bacteria had eyes even they wouldn't be able to see all of them.

Answer:
If you mean standing up for what you think is right, it feels morally correct.
Our beliefs are one of the aspects that define us as human beings.
So when we stand up for what we believe is right, we will prove ourselves to the people who surround us.
Ever stood up to that kid who pushed another kid into a trash can at school?
That’s an example of taking a stand.
When we stand up for what we believe is right, it helps us feel good about ourselves.
I hope this helps a bit.
