Plastic waste reduction

Plastic waste is one of the greatest threats to ocean health worldwide. It is estimated that between 4 and 12 million metric tons of plastic enter the ocean each year, with 80% of marine plastic pollution originating on land. This plastic waste includes shopping bags, takeout containers, water bottles, toothbrushes, toys, and much more.

Reduce Single-Use Plastic Consumption

The easiest way to reduce plastic waste is by refusing single-use plastics, such as plastic bags, water bottles, straws, cups, utensils, and takeout containers. Instead, opt for reusable alternatives like grocery bags, produce bags, bottles, utensils, and coffee cups.

Support Legislation to Curb Plastic Production and Waste

In addition to individual behavioural changes, supporting legislation that reduces plastic production, improves waste management, and holds plastic producers accountable for the waste they generate is crucial. This includes advocating for local, national, and international laws and policies that ban or tax unnecessary single-use plastic items.

Participate in Beach or River Cleanups

Joining or organizing cleanups of local beaches or waterways is a direct and rewarding way to remove plastic waste from the ocean and prevent it from reaching there.

Avoid Products Containing Microbeads

Microbeads are tiny plastic particles found in some face scrubs, toothpastes, and body washes. These microbeads enter our oceans and waterways through sewer systems and negatively impact marine life. Opt for products with natural exfoliants like oatmeal or salt instead.

Support Organizations Addressing Plastic Pollution

There are many non-profit organizations working to reduce and eliminate ocean plastic pollution, such as the Plastic Pollution Coalition, 5 Gyres, and the Plastic Soup Foundation. Supporting these organizations through donations or volunteering can make a significant impact.

Boycott Plastic Bags

Plastic bags are a major contributor to plastic waste. Urge local governments to introduce legislation that discourages plastic bag use, such as taxes or bans. This has already been implemented in cities like San Francisco and Chicago, with positive results.

Choose Clothing Made from Natural Fibers

Synthetic fibers, such as nylon, acrylic, polyester, and fleece, are a significant source of microplastics in the ocean. These fibers shed from our clothing and end up in the water supply. Opting for clothing made from natural materials like cotton and wool can help reduce this source of plastic pollution.

Reducing plastic waste is essential to decreasing water pollution and protecting our oceans and marine life. By making conscious choices and supporting legislative action, we can all play a part in creating a healthier and more sustainable future.

Water conservation

Reduce Water Usage

Limiting water usage is one of the most effective ways to conserve water. This can be achieved by adopting simple habits such as turning off the tap while brushing teeth or shaving, taking shorter showers instead of baths, fixing leaky faucets and pipes, and using water-efficient appliances like low-flow showerheads and toilets.

Reuse and Recycle Water

Reuse water whenever possible, such as using greywater (wastewater from activities like laundry, dishwashing, and bathing) for irrigating gardens or flushing toilets. Additionally, recycled water can be utilized for specific purposes like industrial cooling or landscape irrigation, reducing the demand for freshwater.

Promote Water-Efficient Agriculture

Agriculture is a significant consumer of water, and implementing water-saving techniques in this sector can have a substantial impact. This includes practices such as drip irrigation, precision farming, and crop rotation, which minimize water waste and maximize crop yields.

Protect and Restore Water Ecosystems

Water ecosystems like wetlands, rivers, and lakes play a vital role in filtering and purifying water naturally. Conserving and restoring these ecosystems helps maintain water quality and supports biodiversity. This can be achieved by preventing pollution, minimizing the use of pesticides and fertilizers near water bodies, and restoring natural habitats.

Treat and Reuse Wastewater

Proper treatment of wastewater is essential to remove harmful contaminants before releasing it back into the environment. Treated wastewater can then be reused for various non-potable purposes, reducing the strain on freshwater sources.

Raise Awareness and Educate

Community engagement and education are crucial for successful water conservation. Educating people about the importance of water conservation, the impacts of water pollution, and simple water-saving techniques can foster a sense of responsibility and encourage individuals to take action.

Green agriculture

Reduce Agrochemical Use

Agrochemicals, such as pesticides and fertilizers, are a significant source of water pollution. Excessive use of these chemicals can contaminate water bodies through runoff and leaching. By reducing the application of pesticides and optimizing the use of fertilizers, farmers can minimize the amount of chemicals entering water systems. Integrated Pest Management (IPM) strategies, which utilize natural predators and biological controls, can be employed to reduce reliance on synthetic pesticides.

Implement Buffer Zones

Establishing buffer zones, or protection zones, along water bodies and within farms can act as a natural filter and prevent pollutants from reaching water bodies. These zones, often vegetated with riparian or water-friendly plants, absorb and break down pollutants, reducing their concentration before they enter rivers, lakes, or streams.

Improve Irrigation Techniques

Inefficient irrigation methods can lead to over-irrigation, resulting in excess water flowing off fields and carrying pollutants into nearby water bodies. By adopting efficient irrigation schemes, such as drip irrigation or precision irrigation, farmers can reduce water usage and minimize the migration of fertilizers and pesticides into water sources.

Promote Sustainable Livestock Management

Livestock production contributes significantly to water pollution, particularly through manure and urine. Implementing sustainable practices, such as rotational grazing and improved manure management, can reduce the impact on water quality. Manure storage facilities, such as covered lagoons or anaerobic digesters, can help prevent runoff and provide an opportunity for treating waste before it is applied to fields as fertilizer.

Encourage Conservation Agriculture

Conservation agriculture aims to minimize soil disturbance, maintain permanent soil cover, and diversify crop rotations. By reducing tillage, erosion is decreased, and soil health is improved, reducing the risk of sediment runoff into water bodies. Additionally, crop rotation can enhance soil fertility and reduce the need for chemical inputs, further minimizing the potential for water pollution.

Integrate Agroecology and Aquaculture

Integrating crops, livestock, and aquaculture in a sustainable manner can optimize resource use and reduce pollution. For example, waste from livestock or aquaculture can be treated and used as fertilizer for crops, reducing the need for chemical inputs. This integrated approach creates a symbiotic relationship between different agricultural components, minimizing waste and maximizing the efficient use of resources.

Stormwater management

One crucial aspect of stormwater management is proper waste disposal. This includes disposing of litter, cigarettes, and pet waste in bins, as well as composting leaves and garden clippings instead of letting them wash into drains. It is also important to ensure that paints, solvents, and other toxic substances are cleaned up properly and disposed of at designated recycling centres.

Vehicle maintenance is another important factor in stormwater management. Motor oil, coolant, and other automotive fluids can leak from cars and contaminate stormwater. Regular vehicle maintenance, such as fixing leaks and ensuring proper fuel combustion, can help prevent these pollutants from entering the water supply.

The use of pesticides, herbicides, and fertilisers should be reduced or replaced with natural alternatives. These chemicals can be toxic to aquatic life and contribute to nutrient pollution, leading to harmful algal blooms. Replanting areas of disturbed soil and stabilising riverbanks with vegetation can also help control soil erosion and reduce stormwater pollution.

In addition to individual actions, local governments and businesses play a significant role in stormwater management. Local councils are responsible for controlling and maintaining stormwater systems, while businesses can implement industry-specific practices to reduce stormwater pollution.

By following these stormwater management strategies, individuals, communities, and governments can work together to minimise water pollution and protect our precious water resources.
