Sources of Pollution Plastic Debris ● ○ 80% of pollution to the oceans comes from land Toxic chemicals from industries ● Industrial and agricultural waste ○ Large scale oil spills ● Crude oil that is released in the sea lasts for years, ○ and is harmful to marine life. Resulting animals to be suffocated, which leads to death after entrapment. Littering ● More than 5 trillion plastic particles are littered into ○ the ocean per year https://www.youtube.com/watch?v=4wH878t78bw https://www.conserve-energy-future.com/causes-and-effects-of-ocean-pollution.php
Noise Pollution Sea creatures use sound to ● communicate. Commercial tankers ● 60,000 ships ○ Oil ships ● Interesting Fact: Sound travels 4 Air compression seismic blasts ○ times faster in water than in the air. every 10 seconds Sound can travel 2,500 miles ○ (~4,000 km) https://www.nrdc.org/stories/ocean-pollution-dirty-facts http://www.tehrantimes.com/news/421181/Noise-pollution-in-Iran-s-megacities-20-times-above-standards

Nonpoint vs. Point Source Pollution 1) Nonpoint Source 2) Point Source http://www.noaa.gov/resource-collections/ocean-pollution
Nonpoint Source Pollution Definition: “NPS pollution is caused by rainfall ● Runoff ● or snowmelt moving over and through the City streets → Streams → Rivers → ○ ground. As the runoff moves, it picks up and carries away natural and human-made Oceans :( pollutants , finally depositing them into lakes, Street trash, Car fluid (oil), ■ rivers, wetlands, coastal waters and ground waters” (EPA, 2017). nutrients Farm and crop fertilizer ○ Algal blooms ■ Difficult to control ○ http://www.noaa.gov/resource-collections/ocean-pollution
Rubbish in the Ocean Plastic: most common element of pollution found in the ocean ● Microplastic ○ Eaten by marine life → entering our food source ■ UK Study ■ Fishing nets ● Nutrients and algal blooms ● Creating “dead zones” ○ https://www.independent.co.uk/environment/glitter-ban-environment-microbead-impact-microplastics-scientists-warning-deep-o cean-a8056196.html
“Rubbish Trash Vortex” Largest: The Great Pacific Garbage Patch ● Estimated to be more than twice the ○ size of Texas Two separate patches circulating on a ● current caused by the clash of warm and cold water Complicated clean up ● Microplastics ○ UK ban on microbeads ● https://www.independent.co.uk/environment/glitter-ban-environment-microbead-impact-microplastics-scientists-warning-deep-ocean-a805 6196.html
“Dead Zones” Primary cause: Nutrients pollution from runoff ● Creating an excess of algae ○ Why’s that bad? ○ Algae sinks and decomposes, ● which takes up oxygen “Hypoxia” ● Over 400 worldwide ● http://aquaculturedirectory.co.uk/the-three-biggest-threats-to-global-fisheries-climate-change -pollution-and-overfishing/
Point Source Pollution Definition: “Any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack” (Hill, 1997). Specific instances that are very dangerous for the ● ocean, but are less common and easier to regulate Examples include, but not limited to… ● Factories ○ Animal Agriculture ○ Pipe bursts/ Oil spills ○ http://content.time.com/time/health/ article/0,8599,1984338,00.html
Oil Spills ● Gulf War Oil Spill (1991) ○ Estimated 450 million gallons ○ Act of War ● BP Deepwater Horizon Oil Spill (Jarhead) ○ Estimated 210 million gallons ○ Estimated 14 billion in clean-up ○ Lasted 87 days ● Catistraphic for marine life and the ecosystem ○ Hydrophobic
Possible Solutions 1. Local and Personal Conscientiousness ● “Thinking globally and acting locally” ● In the home ● In the community ● Local legislation Source: https://www.sailorsforthesea.org/programs/ocean-watch/plastic-pol lution-and-its-solution
Possible Solutions 2. Preventing Existing Channels of Waste ● “about 90% of all the plastic that reaches the world’s oceans gets flushed through just 10 rivers” ● Common theme among these regions? ● Possible Solution: implementation of waste collection systems and proper recycling infrastructures in these Source: regions http://www.dw.com/en/almost-all-plastic-in-the-ocean-c omes-from-just-10-rivers/a-41581484

Health of the Planet and People The Health of the Planet is dependent on oceans, which are ~70% of the Earth. If the ● ocean suffers, we all suffer. The planet is in critical danger due to human derived damage. It’s all of our ● responsibility to mitigate damage to our oceans and environment. This section will cover: Corporations Consumers Economics Human health and our relationship with the environment
The Corporation Corporations are by nature psychopaths. Maximum profits and returns to shareholders will always supercede the right and responsible thing to do if left unchecked. Health of the planet is not on the list of priorities of any decent size corporation. Adam Smith (father of capitalism): “When the regulation, therefore, is in favor of the workmen, it is always just and equitable; but it is sometimes otherwise when in favor of the masters. Chapter x, Part II, p. 168.” Marketing: How corporations and even governments can program people and hijack collective consciousness, change what is deemed “normal”. Green washing.

Corporate Industrial Food & Supermarkets vs. Farmers Markets & Local Food Food For Thought: ● Corporations will take the path of cheapest manufacturing for products in order to maximize profits. Is this at the expense of the environment and our health? ● Do corporations have our best interests in mind?
Farmers Markets and Local Food
Consumers, Consumerism, Materialism “Just as there is a dichotomy in law: innocent until proven guilty as opposed to guilty until proven innocent , let me explain my rule as follows: what Mother Nature does is rigorous until proven otherwise; what humans and science do is flawed until proven otherwise.” - Nicholas Nassim Taleb, Antifragile Questions to consider: -Why do we want new stuff? The latest fashion, gadgets, cars? -Why do we take the path of most convenience ? Is it ethical? (Fast food, excessive shopping?) -Are we consumers, or are we people? Is the environment a resource to be exploited? -What do corporations want from us? Understanding dopamine dependence and its role in our society and lives. -Who wins in our economy? Who loses?
Critical Thinking Just because certain behaviors and patterns are normal, doesn’t mean it’s good. The difference between declarative and normative statements. The importance of critical thinking - why are you doing what you’re doing? ● What motivates you? ● Where are you getting your information ● from?

What do we take for granted that we think is true? What paradigms do we hold on How is this related to plastic in the oceans and to? pollution? How can we stop being affected by marketing ● and peer pressure, and come to our own conclusions?
