Garbage island
The document discusses garbage islands, also known as the Great Pacific Garbage Patch, which is a massive area of marine debris trapped in the North Pacific Ocean by ocean currents. It contains high amounts of plastics, chemicals, and other trash, making it the largest landfill in the world. Around 10% of the plastic produced annually ends up in oceans, where it damages marine life and ecosystems. This plastic is eventually eaten by fish and smaller organisms, entering the human food chain and posing health risks. While efforts are underway to prevent further growth, fully cleaning up the patch is extremely challenging due to its vast size and remote location in international waters.
Autonomous Marine Systems, A Driver of Growth in the Blue Economy
Currently, an industrial revolution is unfolding under the seas. Rapid progress in the development of autonomous systems, robotics, maritime surveillance, satellite systems, AI, and data science are opening up whole new sectors of ocean use and research.
Oceanic trash
The document discusses garbage patches in oceans, specifically the Great Pacific Garbage Patch. It is the largest accumulation of ocean plastic in the world, located between Hawaii and California. The patch contains debris ranging in size from large abandoned fishing nets to microplastics. It is estimated to cover 1.6 million square kilometers and contain over 1.8 trillion pieces of plastic, weighing around 80,000 tons. The plastic harms marine life and enters the human food chain. Solutions proposed include cleaning up existing patches using interceptor systems and preventing further plastic from rivers by intercepting waste before it reaches the oceans.
Plastic Bag Pollution - The Problem and Solutions
This deck examines the facts regarding current plastic pollution and potential solutions with an emphasis on plastic bags.
Why recycling is important
This document discusses the importance of recycling and the current state of recycling different materials. It notes that most plastic and metals are not recycled and end up in landfills or oceans, causing pollution. Paper recycling has dropped significantly from 12,000 years ago due to cutting down about 15 billion trees per year. Recycling rates remain low for plastics and metals, though higher for paper in the US and Japan. The conclusion states that recycling helps the environment, conserves resources, and everyone should work to increase recycling rates given the large scale of environmental problems.
Commotion in the Ocean
These studies examine various impacts of climate change on oceans and marine life. They find that climate change is causing water temperatures and acidity to rise, damaging coral reefs and reducing shark and fish populations. This poses serious threats such as declining ocean biodiversity and fisheries. The studies also show the ocean is absorbing more carbon dioxide than previously estimated, though this comes at the cost of further acidification. Collectively, the research enhances understanding of climate change effects and calls for action to mitigate further damage.
Marine Polution
Marine pollution threatens ocean ecosystems and human uses of the ocean. The National Oceanic and Atmospheric Administration's Marine Debris Program aims to investigate, solve problems, and protect marine environments from debris. Major sources of marine pollution include debris from the 2011 Japan tsunami and polluted urban runoff. Solutions involve cleanups, education, improved waste management, and recycling programs like Fishing for Energy that convert discarded fishing nets into energy. Preventing marine pollution benefits ocean life, coastal communities, and continues human enjoyment of ocean resources.

The Great Pacific Garbage Patch
Human pollution, especially plastic waste, is endangering many animal species. The 'Great Pacific Garbage Patch' has accumulated plastic trapped in ocean currents in an area twice the size of France. Plastic is affecting species by being ingested and accumulating in stomachs. Green sea turtles have plastic interfering with nesting and threatening their endangered status. Scientists measure impacts on populations and plastic quantities to study problems and encourage solutions.

Lake superior 2013 annual report-final aug-26-13
Lake Superior is the largest and cleanest of the Great Lakes, home to diverse plant and animal species. While its ecosystem remains in good condition, threats such as invasive species, land use change, contaminants, and climate change require continued protection efforts. The Lakewide Action and Management Plan (LAMP) is the mechanism for the US and Canada to cooperate on monitoring the lake and taking actions to address these threats, with a focus on habitat restoration, reducing chemical pollutants, and adapting to climate change. Ongoing challenges include legacy contaminants in fish, emerging chemicals of concern, and stresses from climate change such as warming waters impacting cold-water fish species.
Gwyn Williams - Sustainable Severn Forum 2017
This document summarizes a presentation given by Gwyn Williams on the threats to biodiversity from human activities and climate change. Some key points include:
- Species abundance in the UK has declined significantly since 1970 according to conservation indices.
- Protected areas have helped conserve some species but large-scale species range shifts are projected due to climate change.
- A rapid transition to a low-carbon economy is needed to address climate change but must be achieved in a way that is sustainable and does not further deplete nature.
- The presentation examines options for tidal energy generation in the Severn Estuary and concludes that more research is needed to understand potential ecological impacts before large-scale development.
Single use plastic pollution in our oceans
Nearly 8 million metric tons of plastic enter the world's oceans each year, polluting the marine ecosystem. Plastic pollution has long term negative effects on marine life and is nearly impossible to reverse. Citizens, governments, environmental groups, and businesses all contribute to the problem. A proposed solution is to further limit single-use plastics through legislation and raising awareness of alternatives. California has already enacted a plastic bag ban, but recent efforts to pass broader legislation limiting other single-use plastics have failed. Stakeholders must find resolutions to curb plastic pollution.

How to prevent Ocean pollution?
The oceans cover over 70% of the globe. Its health, wellbeing of humanity and the living environment that sustains us all are inextricably linked. Yet neglect of ocean acidification, climate change, polluting activities and over-exploitation of marine resources have made oceans, one of the earth’s most threatened ecosystems.
Marine pollution, also known as ocean pollution, is the spreading of harmful substances such as oil, plastic, industrial and agricultural waste and chemical particles into the ocean.
Christchurch Business Keynote - Vicki Buck
This document discusses the rapid urbanization of the world's population and its implications for climate change and the environment. Some key points:
- For the first time in history, over half the world's population lives in urban areas, a proportion that is projected to reach 60% by 2030.
- Much of the expected growth in global population by 2050 will occur in cities in the poorest countries.
- Coastal cities are vulnerable to rising sea levels, and small island nations are at risk of becoming uninhabitable due to climate change. Millions may become "climate refugees" with nowhere to relocate.
- New Zealand has among the highest per capita carbon emissions in the world,

Surfers Against Sewage (SAS) is an environmental charity established in 1990 to protect UK oceans, waves, and beaches. SAS campaigns on issues like marine litter, wave protection, water quality, climate change, and education. Their work includes influencing government policy, organizing volunteer cleanups, educating communities, and challenging industry standards. Through campaigns targeting plastic pellets, sewage overflows, and climate change impacts, SAS raises awareness and advocates for cleaner and safer seas.
Bandalong Litter Trap
This document describes the Bandalong Litter Trap, a device that prevents litter from entering waterways and oceans. It notes that 80% of marine debris comes from land and plastic pollution is a major problem, entangling and being ingested by wildlife. The litter trap has been successfully used for over 15 years worldwide, removing tons of trash annually. It creates awareness about pollution issues and inspires community involvement in cleanups. The litter trap is a proven solution that forms partnerships to address the growing problem of ocean debris.
MarineLitterVG
This document defines marine litter as any waste created by humans that has entered the ocean environment. Plastics make up 60-90% of marine litter. Plastic pollution is a major problem because plastics do not biodegrade and can persist in oceans for centuries, accumulating in habitats and entering food chains. Marine litter comes in all sizes, from large objects like fishing gear to microplastics smaller than 5mm that are difficult to monitor due to their small size. More research is needed to understand microplastics' impacts on ecosystems and human health.
Everything you need to know about climate change, in cartoons!
This document provides an overview of climate change impacts and solutions through a series of cartoons and captions. It discusses:
- Temperature and sea level rise that has already occurred and is projected.
- Impacts on wildlife such as extinction rates exceeding any time in the past 65 million years.
- Effects on food including potential reductions in fish catches and crop yields.
- The remaining carbon budget and timeline for action to limit warming given current emissions rates.
- Progress needed on renewable energy, electric vehicles, and other solutions to meet long-term decarbonization targets.
- Behavior changes around diet, transportation, housing that can significantly reduce emissions.
Isaiah Adkins Civic presentation
Plastic pollution has become a major global problem, with millions of tons of plastic waste entering oceans and waterways each year. This plastic debris harms wildlife and ecosystems. The amount of plastic in the oceans is projected to triple by 2040 without action. Cleanup organizations like the Missouri River Relief and Ocean Conservancy work to reduce plastic pollution and its impacts through volunteer cleanups, advocacy, education, and research. Addressing plastic pollution will require collective global action from governments, businesses, and individuals to reduce plastic use, improve recycling, support cleanup efforts, and adopt more sustainable practices.
Environment student soc 5 5 sp2014
The document discusses various environmental issues such as deforestation, climate change, pollution, and their causes and impacts. It notes that deforestation in the Amazon rose significantly from 2000-2009 mainly to clear land for cattle pastures and agriculture. Approximately 80% of deforestation is attributed to agriculture. Cattle breeding in Brazil also contributes as it is profitable and currency fluctuations have incentivized expansion. These activities release greenhouse gases and damage habitats, wildlife, and global climate stability. Solutions proposed include renewable energy, more fuel efficient vehicles, and using hemp as an environmentally friendly alternative.

Emergency on Plant Earth - Turtles
This document discusses the Tulap Sea Turtle Project in Sulawesi, Indonesia. The project aims to protect sea turtles nesting on local beaches and involves activities like maximizing successful nesting and hatching, enabling hatchlings to safely reach the sea, and developing harmony between coastal villages and ecology. It notes the threats facing sea turtles like coastal pollution, destructive fishing, poaching, and discusses the species that nest in the area. Students will be learning about turtle ecology, threats they face worldwide, and evaluating solutions to the problem of plastic pollution in oceans. A beach cleanup is planned where students will assess causes and extent of beach pollution to critically analyze solutions.

Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
