Reduce plastic use
Plastic pollution is one of the greatest threats to ocean health. It is a global crisis that requires urgent action. While plastic debris can be removed from the ocean, it may be impossible to clean up some items. Therefore, reducing plastic use is crucial. Here are some ways to reduce plastic use and help solve the problem of ocean pollution:
Avoid Single-Use Plastics
Single-use plastics, such as plastic bags, straws, beverage bottles, and food packaging, are major contributors to ocean pollution. These items can take hundreds of years to decompose and have devastating effects on marine wildlife. Opt for reusable alternatives whenever possible, such as cloth bags, metal straws, and glass or stainless-steel water bottles.
Support Biodegradable and Eco-Friendly Options
When possible, choose products made from biodegradable or compostable materials. While some "biodegradable" plastics require higher temperatures to break down than those found in the ocean, there are more sustainable options available. For example, paper straws, bamboo toothbrushes, and plant-based packaging are becoming more widely available and can help reduce plastic waste.
Refuse, Reuse, and Recycle
Refuse plastic products whenever possible, and choose reusable items instead. Bring your own containers for takeaway food and drinks, and opt for second-hand items to reduce the demand for new plastic products. Additionally, recycling plastic items whenever possible can give them a new lease of life and prevent them from ending up in the ocean.
Buy in Bulk and Support Sustainable Businesses
Purchasing items in bulk can reduce the amount of plastic packaging used. Buying from local businesses that offer refillable or package-free options can also help. Supporting sustainable businesses that use minimal plastic packaging and promote eco-friendly practices can drive change and reduce plastic pollution.
Educate and Advocate
Spreading awareness about the impacts of plastic pollution and sharing ways to reduce plastic use can empower others to make changes. Advocate for policies and regulations that address plastic pollution, such as bans or limits on disposable plastic items. Supporting organisations like The Ocean Cleanup, which aims to remove 90% of floating ocean plastic by 2040, can also make a significant difference.

Properly dispose of chemicals
Properly disposing of chemicals is crucial to preventing ocean pollution and protecting the environment and human health. Chemical waste can be toxic, corrosive, flammable, or reactive, and improper disposal can lead to adverse effects on the delicate ecological balance. Here are some detailed instructions for properly disposing of chemicals:
Identification and Separation:
Identify household hazardous waste, such as cleaning agents, paints, batteries, herbicides, pesticides, and health and beauty products. Separate these items from regular waste to prevent contamination.
Storage:
Store identified chemicals in their original containers to prevent mixing. Plastic bottles are preferred for storing hazardous waste when compatibility is not an issue. Segregate chemical waste by compatibility, not alphabetically. Ensure proper labelling and record-keeping, including the chemical name, quantity, date of waste generation, and place of origin.
Collection and Transportation:
Collect and manage chemical waste according to local regulations and protocols. Work with your local Environmental Health and Safety Department (EHS) to ensure proper handling, storage, and transportation. Obtain the necessary tags and forms for hazardous waste disposal.
Offsite Disposal:
Remove chemical wastes from labs, workplaces, and other areas where they are generated, and transport them to offsite disposal facilities. Ensure that containers are individually tagged, sealed, and not leaking. Comply with regulations governing the disposal of hazardous waste, such as the Resource Conservation and Recovery Act (RCRA) in the United States.
Waste Treatment:
Understand the properties of hazardous waste and seek professional guidance on treatment methods. Waste-treatment sites must prevent the mixing of incompatible chemicals and the disposal of unstable chemicals. Incineration, chemical treatment, and specialised landfills designed for chemical waste are common disposal methods. However, always prioritise eco-friendly and sustainable options to minimise environmental impact.
