What You'll Learn
Reduce plastic use
Plastic pollution is one of the greatest threats to ocean health worldwide. With skyrocketing plastic production, low levels of recycling, and poor waste management, between 4 and 12 million metric tons of plastic enter the ocean each year. This is enough to cover every foot of coastline on the planet.
The first step towards a solution is to reduce plastic use. Here are some ways to do this:
Reduce, Reuse, and Recycle
The most effective way to reduce waste is to not create it in the first place. Set your table with cloth napkins and reusable dishes, glasses, and silverware as often as possible. Bring your own reusable bag for carrying purchases and try to buy items with minimal packaging. If you bring your lunch, package it in reusable containers instead of disposable ones. When buying second-hand items, opt for used plastic products that can be reused.
Avoid Single-Use Plastics
Half of all plastic produced is for throwaway items that are used once and then discarded: grocery bags, plastic wrap, disposable cutlery, straws, coffee cup lids, water bottles, dry cleaning bags, and takeout containers. Refuse any single-use plastics that you do not need and purchase reusable versions of these products.
Be Mindful of Microplastics
Microplastics are tiny particles of plastic that float through marine habitats and can be ingested by animals. A study found that plastic cutting boards could be a significant source of microplastics in our diet. Approach cosmetics with caution, as many popular brands contain microplastics. When possible, purchase products made from recycled plastic materials.
Educate and Advocate
As important as it is to change individual behaviors, such changes alone are insufficient to stop ocean plastic pollution. Encourage your household to recycle right and recycle more. When you refuse single-use plastic items, help businesses by letting them know that you would like them to offer alternatives. Direct local businesses, city offices, and school districts toward programs that can help them reduce plastic pollution and become more sustainable.

Cut down on vehicle emissions
Motor vehicle emissions are a significant source of air pollutants, so cutting down on vehicle emissions is crucial in our efforts to combat climate change and improve air quality.
One way to cut down on vehicle emissions is to choose a modern vehicle with good fuel efficiency and low emissions. When buying a new car, look for vehicles with the best possible fuel economy and low greenhouse gas emissions. Fuel-efficient vehicles can help the environment and save you money on fuel costs. You can use the Green Vehicle Guide to learn about vehicles that are more efficient and less polluting. Premium fuels can also help reduce emissions as they contain active cleaning agents that improve fuel efficiency and lower emissions.
Another way to reduce emissions is to drive efficiently. This includes driving at a slower speed, accelerating and stopping gently, and coasting when possible. Driving at a lower speed can save you fuel over time. Additionally, keeping your windows up while driving can reduce drag and increase fuel efficiency. It is also important to avoid unnecessary idling, as this wastes fuel and produces emissions. Instead, turn off your engine when parked or stuck in traffic for more than 10 seconds, and gently warm up your engine when starting.
Furthermore, maintaining your vehicle can help reduce emissions. This includes getting regular tune-ups, following the manufacturer's maintenance schedule, and using the recommended motor oil. Keeping your car in good repair and fixing any issues with the exhaust and oxygen sensor can also help reduce emissions.
By following these tips, you can help reduce vehicle emissions, improve fuel efficiency, and contribute to a healthier environment.

Plant trees
Planting trees is a great way to reduce pollution and improve air quality, particularly in urban areas. Trees have a remarkable ability to reduce air pollution through several mechanisms. Firstly, they can reduce air temperature, which in turn alters pollution concentrations. Lower temperatures mean less energy consumption in buildings, which reduces air pollutant emissions from power sources.
Trees also directly remove pollutants from the air by absorbing gaseous molecules. The tiny pores on tree leaf surfaces, called stomata, take in air that includes toxic pollutants. Once inside the leaf, the gases diffuse into the intercellular spaces and react with the inner-leaf surfaces. This process permanently converts pollutants like sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and ozone. These are key indicators of air quality, classified as "criteria air pollutants" by the Environmental Protection Agency.
Trees also help by temporarily intercepting airborne particles. Their leaves and stems catch fine particulate matter (PM2.5), preventing it from floating in the air and causing respiratory issues. When it rains, these particles are dissolved in stormwater runoff or transferred to the soil. This interception of particulate matter contributes to improved air quality and reduced health risks associated with inhaling harmful pollutants.
In addition to their air-purifying abilities, trees offer other benefits in urban settings. They can help cool our homes and surroundings, reducing the need for energy-intensive cooling systems. Trees also release oxygen into the atmosphere, further enhancing air quality.
When considering tree-planting initiatives, it is important to acknowledge that wind direction and landscape structure can influence the movement of pollution. In narrow streets surrounded by tall buildings, for example, airflow can trap pollutants close to the ground. In such cases, hedges or green walls are generally preferred over tall trees with large canopies, as the latter can impede the dispersal of pollution. On the other hand, broad roads surrounded by low-rise buildings allow for more free-flowing air, making both trees and hedges viable options.
Conifers, with their dense needle-like leaves, are excellent choices for reducing particulate matter due to their canopy structure. As evergreen species, they act as year-round filters, though their sensitivity to soil salt levels is a consideration, especially in de-iced urban roads.
By strategically planting trees, such as conifers, in suitable locations, we can effectively harness their pollution-fighting capabilities and create healthier, more sustainable urban environments.

Avoid backyard fires
Backyard fires are a significant source of air pollution, particularly in cities. Smoke from burning wood contains a complex mixture of gases and fine particles, including nitrogen oxides, volatile organic compounds (VOCs), carbon monoxide, and particle pollution. These compounds have detrimental effects on the environment and human health. Here are some ways to avoid backyard fires and minimise their impact:
Limit backyard fires:
- Be mindful of the frequency and duration of your fires. Keep fires small and brief, preferably 3 feet across or less.
- Choose dry firewood as it burns cleaner and produces less smoke. Avoid burning green wood, construction waste, plastic, garbage, or yard waste. These materials create more smoke and release toxic compounds.
- Be a good neighbour and consider the impact of your fire on others, especially those with asthma and lung conditions. Avoid burning during air quality alerts or stagnant weather conditions.
- Sign up for notifications about elevated air pollution levels and avoid burning when possible.
Explore alternative heat sources:
- Consider switching to natural gas or propane burners for your fire pit or outdoor fireplace. These alternatives produce fewer harmful air pollutants. Conversion kits are available at hearth and patio stores.
- Opt for electric or hand-powered alternatives for lawn equipment instead of gas-powered engines, which often lack pollution control devices.
Practice fire safety:
- Check local regulations and restrictions before starting any fire. Some areas may prohibit backyard recreational fires.
- Avoid burning when it is windy, as this can spread sparks and embers, potentially igniting nearby vegetation or structures.
- Always have water nearby, such as a garden hose, to extinguish the fire completely and "mop up" the ashes.
- Create a clearing around your fire pit by removing flammable materials within a radius of 10 to 25 feet, especially if it is windy and dry.
By following these guidelines, you can minimise the impact of backyard fires on the environment and your community while still enjoying the warmth and ambiance of a fire responsibly.

Choose natural fibres
Synthetic fibres, such as polyester and nylon, are significant contributors to plastic pollution. These fibres are designed to resist degradation and can take thousands of years to disintegrate, breaking down into smaller and smaller components that are challenging to remove from the environment. As they do not easily dissolve in water, synthetic fibres absorb other substances, including oil residue and pollutants like polychlorinated biphenyls, which can be harmful to both the environment and human health.
Natural fibres, on the other hand, offer a more sustainable alternative. Derived from plants, animals, and minerals, they have been a staple in the textile industry for thousands of years due to their breathability, biodegradability, and comfort. Here are some reasons to choose natural fibres:
Biodegradability
Natural fibres typically decompose within months, ensuring that they do not persist in the environment like synthetic fibres. This helps reduce the amount of waste that ends up in landfills and contributes to a healthier ecosystem.
Low Carbon Footprint
Compared to synthetic fibres, natural fibres often have a lower carbon footprint. For example, linen, which is derived from the flax plant, uses less water and energy during production compared to cotton or polyester. Additionally, flax can grow in poor soil, reducing the need for land that could otherwise be used for food production.
Circular Economy
Many natural fibres are derived from agricultural by-products, supporting the concept of a circular economy. For instance, piña, or pineapple leaf fibre, is made from agricultural waste, while recycled polyester is created from recycled plastic bottles, diverting waste from landfills.
Health Benefits
Synthetic fibres can release microfibres during washing, which can end up in our food and drinking water. These microfibres may be treated with additives, such as flame retardants, and can absorb pesticides and other industrial chemicals. By choosing natural fibres, you reduce your exposure to these potential health hazards.
Eco-Friendly Alternatives
When making textile purchases, look for eco-friendly alternatives derived from natural fibres. Organic cotton, for example, is grown without harmful pesticides or synthetic fertilizers and uses significantly less water than conventional cotton. Other options include hemp, which enriches soil health and requires minimal water, and jute, which is fully biodegradable and grown without pesticides.
By choosing natural fibres over synthetic ones, you can play a part in reducing pollution and its impact on the environment and human health.
