Avoid plastic microbeads in cosmetics
Marine pollution is a pressing issue, with plastic pollution being one of the greatest threats to ocean health. Plastic debris takes hundreds of years to degrade and breaks down into ever-smaller particles, known as microplastics, which have harmful environmental impacts. One type of microplastic, microbeads, has become a growing source of ocean plastic pollution. Microbeads are tiny plastic particles used in cosmetics and personal care products for scrubbing or exfoliating. They are found in face scrubs, toothpastes, body washes, sunscreens, shampoos, makeup, and deodorants. These microbeads slip through water treatment plants and enter our oceans and waterways through our sewer systems, affecting hundreds of marine species.
To avoid plastic microbeads in cosmetics, it is important to be an informed consumer. Check the ingredient labels of cosmetic products for terms like "polyethylene" and "polypropylene," which indicate the presence of plastic microbeads. Opt for products with natural exfoliants, such as oatmeal or salt, instead. You can also look for certifications or logos indicating microplastic-free products, such as the "Look for the Zero" logo, which has been awarded to 150 brands. Additionally, stay informed about plastic pollution issues and support campaigns like "Beat the Microbead," which has led to 19 countries taking steps to ban microbeads.
It is worth noting that the term "microplastic" lacks a consistent definition, and there is limited research on the presence and impact of microplastics in "leave-on" cosmetic and personal care products. However, due to the potential health and environmental risks, it is crucial to choose cosmetic products wisely and support initiatives for comprehensive regulations and monitoring of microplastics in the industry.
Finally, you can encourage cosmetic companies to demonstrate their social responsibility by reducing the use of plastic microbeads. Safer alternatives, such as silica microspheres, are growing in popularity. Silica microspheres, derived from silicon dioxide, offer a sustainable and natural option that enhances the performance of skincare and cosmetic formulations without the risks associated with plastic microbeads. By supporting these alternatives, you can help reduce the presence of plastic microbeads in cosmetics and contribute to the protection of our oceans and marine life.

Properly dispose of toxic chemicals
Marine pollution is a pressing issue, with our oceans being contaminated by chemicals and trash. It is important to properly dispose of toxic chemicals to reduce the impact on marine life and ecosystems. Here are some ways to do this:
Firstly, it is crucial to understand the types of toxic chemicals that are commonly found in marine environments. These include herbicides, pesticides, and cleaning products, and fertilizers. Many of these chemicals are designed to kill or harm certain organisms and can have devastating effects on marine life if they enter water bodies. Always opt for non-toxic alternatives.
Secondly, proper disposal methods for these chemicals vary and should be followed carefully. Many communities have specific guidelines for the disposal of hazardous waste. Some chemicals can be neutralized or deactivated, while others may need to be taken to specialized disposal facilities. Check with your local waste management authority for guidance on how to dispose of specific chemicals.
Additionally, it is important to consider the impact of runoff from land. Chemical fertilizers, oils, and other pollutants from farms, vehicles, and construction sites can be washed into waterways and oceans during rainfall or irrigation. To mitigate this, reduce the use of chemical fertilizers, and opt for organic alternatives that are less harmful to the environment. When using any chemicals, ensure you follow the instructions carefully and do not overuse or misuse them.
Furthermore, be cautious when using cosmetic products that contain microplastics or microbeads. These tiny plastic particles are often found in facial scrubs, toothpastes, and body washes. Due to their small size, they can pass through water-treatment plants and enter oceans and waterways, affecting marine life. Opt for products with natural exfoliants, such as oatmeal or salt, or choose cosmetic brands that do not use microplastics.
Lastly, stay informed and educate others about the proper disposal of toxic chemicals. Learn about the environmental impact of different chemicals and share this knowledge with your community.

Reduce nonpoint source pollution
Nonpoint source pollution is a significant issue, and it is crucial to address it to protect marine environments. Here are some ways to reduce nonpoint source pollution:
Riparian Corridors and Buffer Zones
Riparian corridors are buffer zones between used land and streams, often planted with vegetation. These corridors help regulate water temperature, protect banks from erosion, and filter pollutants from stormwater. Allowing natural growth, adding native plants, trees, and bushes, and establishing a well-maintained riparian corridor can effectively reduce nonpoint source pollution.
Managing Livestock and Pet Waste
Livestock and pets can contribute to nonpoint source pollution through trampling stream banks and depositing waste, leading to increased E. coli levels. To mitigate this, block livestock from directly accessing water bodies and use fences to limit their access. Provide alternative drinking water sources and consider rotational grazing to reduce pasture erosion and promote vegetation growth. For pets, simply picking up their waste with plastic bags can help reduce nutrient and E. coli pollution.
Urban and Suburban Areas
In urban areas, impermeable pavement increases stormwater runoff, leading to downstream flooding, erosion, and nonpoint source pollution. To mitigate this, consider planting rain gardens to catch and infiltrate excess stormwater. Connect downspouts to rain barrels and use that water for irrigation during dry periods. When replacing driveways, opt for porous pavement that allows stormwater to infiltrate the ground, reducing runoff.
Agricultural Practices
Agricultural operations can implement several measures to reduce nonpoint source pollution. This includes using buffer strips or grass planting around construction sites to absorb soil, fertilizers, and pesticides before they reach water bodies. Conservation tillage, where crop residue is left in the field while planting a new crop, reduces erosion and keeps nutrients and pesticides in place. Crop nutrient management involves applying fertilizers sparingly and only after testing fields to ensure efficient use. Additionally, using beneficial insects to control agricultural pests can reduce the need for pesticides.
Proper Disposal of Chemicals and Waste
It is essential to keep oils, chemicals, and waste out of local streams and storm drains. Utilize local toxic drop-off sites and properly dispose of herbicides, pesticides, cleaning products, and other household chemicals. Maintain vehicles to reduce leaks, and never pour any materials down storm drains.
By implementing these measures, individuals, communities, and organizations can work together to significantly reduce nonpoint source pollution and protect marine environments.

Limit ocean dumping
Marine pollution is a pressing issue that poses a serious danger to marine life and ecosystems. One significant contributor to this problem is the dumping of waste into the ocean. To address this issue, it is crucial to implement measures that reduce and eventually eliminate the practice of ocean dumping. Here are some strategies to limit ocean dumping and protect our marine environment:
Implement and enforce regulations:
The Marine Protection, Research, and Sanctuaries Act (MPRSA), enacted by the United States in 1972, was a pivotal moment in the fight against uncontrolled waste dumping in the ocean. This legislation regulates the transportation and disposal of materials that could harm human health and the marine environment. Similar regulations and treaties, such as the London Convention, have been adopted internationally to protect the oceans from deliberate waste disposal. Strict enforcement of these regulations is essential to deterring illegal dumping activities.
Reduce dredging and properly manage dredged materials:
Dredging is a significant contributor to ocean dumping, with approximately 20-22% of dredged material being disposed of in the ocean. To limit this, alternative methods for managing silt and sand buildup in rivers, canals, and harbors should be explored. When dredging is necessary, proper management of the dredged materials is crucial. The EPA, in collaboration with the U.S. Army Corps of Engineers, regulates the disposal of dredged materials and designates specific ocean sites for their release, ensuring polluted materials are handled safely.
Promote recycling and waste reduction:
Recycling and waste reduction play a crucial role in limiting ocean dumping. By encouraging recycling programs and educating communities about proper waste disposal, we can reduce the amount of waste that ends up in our oceans. Additionally, producing less wasteful products and changing dangerous materials into more benign waste can further minimize the need for ocean dumping.
Improve land-based waste management:
A significant portion of marine plastic pollution originates on land. Implementing better waste management practices on land can help prevent plastic and other pollutants from reaching the oceans. This includes proper disposal of herbicides, pesticides, and cleaning products, as well as reducing the use of single-use plastics and promoting sustainable alternatives.
Raise awareness and educate the public:
Educating the public about the impacts of ocean dumping and providing information on how individuals can reduce their plastic consumption and properly dispose of waste can empower people to make environmentally conscious choices. Staying informed about plastic pollution and sharing knowledge with others can create a collective sense of responsibility for protecting our oceans.
