This excess nitrogen and phosphorous comes from agricultural activities including excess fertilizers turning into nitrogenous compounds in the air or polluting nearby water bodies.

This overabundance of nitrogen and phosphorous nutrients (eutrophication) causes phytoplankton and algae to grow and multiply exponentially faster than normal.]]> 2020-09-04 05:42:48 UTC https://padlet.com/sasidhar/o96au8go016k2g1f/wish/720246992 https://padlet.com/sasidhar/o96au8go016k2g1f/wish/720247015 red tides / brown tides - kill all animals in water, then algae decompose, bacteria suck up all the oxygen in water, creates a hypoxial zone with no oxygen where fish can never live again

not only do these algal blooms choke the water, the outcome of their respiration processes are toxic and leave the water in a completely uninhabitable state.

Key terms: hypoxia (state where the  pond is deprived of the appropriate oxygen level)

Effects of acid rain- stress fish, and at high levels, kill them.

Artificial light disrupts circadian rhythms between marine animals and human. At levels, this can cause cancer and kill animals. Fishes are also attracted by light and during their travel to the light, many of them die. ]]> 2020-09-04 05:46:10 UTC https://padlet.com/sasidhar/o96au8go016k2g1f/wish/720250712 19sb0197dishita https://padlet.com/sasidhar/o96au8go016k2g1f/wish/720253365 Garbage patches: Areas with particularly high concentrations of flotsam and jetsam (mostly small pieces of plastic.)

Plastic and float-able other marine debris can travel the currents persistently >> this material accumulates in the ocean gyres centers >> creation of garbage patches

This can contribute to:
1. Toxic chemicals spread in the ocean
2. Snag and tear of corals
3. Harming animals if ingested or got entangled in (the debris)

Water pollution is when people dumb waste material like toxic chemicals, plastic materials and other substances that take a very long time to disintegrate in the water. By the constant dumping of these material, the water is not usable anymore due to the contamination of such pollutants. ]]> 2020-09-04 05:52:31 UTC https://padlet.com/sasidhar/o96au8go016k2g1f/wish/720257352 15sb0068karthikeya https://padlet.com/sasidhar/o96au8go016k2g1f/wish/720257740 One major cause of air pollution is the burning of fossil fuels from both energy plants and vehicles. The combustion of these fuels releases immense amount of carbon dioxide into the atmosphere.

Chemicals like sulfur dioxide, carbon monoxide can cause smog and acid rain when released into the air. The exposure to air pollution can also affect the human body, some concequences are: irritation in the eyes, nose and throat. But, long term exposure to air pollution can lead to chronic respiratory disease, lung cancer and also heart diseases. These gases also affect the atmosphere and lead to global warming.]]> 2020-09-04 05:52:50 UTC https://padlet.com/sasidhar/o96au8go016k2g1f/wish/720257740 https://padlet.com/sasidhar/o96au8go016k2g1f/wish/720258855  Introduces toxic chemicals into seawater resulting in habitat degradation.
