What You'll Learn
Aerosol deodorant use
Aerosol deodorants are a common personal care product that people use without knowing their harmful effects on the environment. Aerosols are known to damage air quality due to the release of volatile organic compounds (VOCs) or V.O.C.s, which interact with other particles in the air to create the building blocks of smog. These compounds can trigger asthma, scar lungs, and are linked to heart attacks, strokes, and lung cancer.
The use of aerosol deodorants increases one's carbon footprint due to the release of compressed gases and hydrocarbons. Additionally, the Environmental Protection Agency has acknowledged that aerosols contain highly toxic and hazardous components such as xylene, formaldehyde, neurotoxins, and carcinogens. These toxic ingredients can cause serious health issues, especially for individuals with chronic diseases.
Aerosol deodorants also have a significant impact on our surroundings. Studies have shown that they can alter rainfall patterns by reducing precipitation and decreasing the size of cloud water droplets. This can lead to changes in climate and weather patterns, further contributing to the negative effects of aerosol deodorant use.
To reduce the impact of aerosol deodorant use, individuals can switch to non-aerosol alternatives or natural deodorants. It is also important to ensure proper ventilation when using aerosol products indoors, as the concentration of particulate matter (PM) released by these products can pose health risks, especially for individuals with chronic diseases.
Governments and regulatory bodies also have a role to play in addressing the issue. Implementing policies that reduce the use of aerosol deodorants, such as educating the public about their harmful effects and encouraging the development and use of eco-friendly alternatives, can help mitigate their impact on the environment and human health.

Leaving taps running
Water wastage is a global issue, with agriculture being the biggest consumer of freshwater resources. Farming and livestock production account for about 70% of surface water use. However, the agricultural sector is also a serious water polluter. Fertilizers, pesticides, and animal waste from farms wash into rivers, streams, and lakes, contaminating water sources and degrading water quality. Leaving taps running only adds to this problem, increasing the amount of water that needs to be treated and potentially contributing to water scarcity.
The act of leaving taps running also has a direct impact on water pollution. When taps are left running, water goes down the drain, often into sewer systems or directly into waterways. This increases the volume of water requiring treatment, putting pressure on sewage treatment facilities. Accidental or illegal releases from these facilities can occur, contributing harmful pathogens and chemicals to nearby waterways. These pollutants can include human and animal waste, bacteria, and viruses, which can make their way into drinking water sources and cause waterborne diseases such as cholera, giardia, and typhoid.
Furthermore, the energy used to pump and treat water is also wasted when taps are left running. The process of pumping, treating, and distributing water consumes a significant amount of energy, often generated by burning fossil fuels. This contributes to air pollution and climate change. By leaving taps running, we are indirectly increasing the demand for energy, leading to more pollution and environmental damage.
To reduce water pollution and conserve this precious resource, it is essential to adopt simple habits such as turning off taps when not in use. Small changes, such as turning off the tap while brushing teeth or washing hands, can save over 1,400 litres of water per person per month. These individual actions collectively make a significant impact on reducing water wastage and pollution, protecting our finite freshwater sources, and ensuring a healthier environment for all.

Drinking bottled water
Plastic water bottles significantly contribute to environmental pollution. Firstly, the production of plastic bottles consumes valuable resources, emits harmful chemicals, and generates greenhouse gases. The plastic pellets are heated to very high temperatures and then injected into molds to create the bottles. This process releases harmful chemicals and gases, contributing to air pollution.
Secondly, during usage, plastic bottles emit microplastics, chemicals, and bacteria into the drinking water, which can have detrimental effects on human health. Microplastics, small pieces of plastic less than 5mm in size, have been linked to various health issues, including oxidative stress, immune system disruption, and changes in blood fat levels. The presence of microplastics in bottled water is concerning, with studies detecting them in up to 78% of samples.
Thirdly, the disposal of plastic bottles is a major environmental issue. Plastic bottles end up in landfills, oceans, and ecosystems, where they release microplastics and toxins that harm wildlife and human health. They contribute to landfill overflow and marine pollution, leading to entanglement and ingestion issues for marine animals.
Additionally, the recycling rate of plastic bottles is low, with most bottles ending up in landfills or being shipped to low- and middle-income countries. The environmental impact is exacerbated by the low recycling rate, as plastic bottles can last forever in landfills.
The bottled water industry is exploring sustainable packaging solutions, such as bioplastics made from dairy waste, to reduce its environmental footprint. However, the key lies not only in finding new solutions but also in rethinking our relationship with single-use plastics and reducing our reliance on them.
Furthermore, bottled water contributes to water source depletion, as companies often bottle water from drought-ridden areas or springs that cannot support the extraction. This can lead to local communities losing access to water sources they rely on.
In conclusion, drinking bottled water can unknowingly contribute to pollution through the production, usage, and disposal of plastic bottles. The widespread use of bottled water has significant environmental and health implications, and efforts to reduce reliance on single-use plastics and improve recycling rates are crucial to mitigate these impacts.

Using single-use plastic bags
People often pollute the environment unknowingly through their everyday habits. For instance, leaving the tap running while brushing one's teeth, drinking bottled water, throwing chewing gum on the ground, using aerosol deodorants, and using single-use plastic bags.
Single-use plastic bags are a significant contributor to environmental pollution, particularly in waterways and oceans. Plastic bags are designed to be used once and then discarded, often ending up in landfills, incinerators, or the natural environment. When plastic bags are disposed of in landfills, they can take up to 1,000 years to degrade, and even then, they do not break down completely. Instead, they photo-degrade, turning into microplastics that continue to pollute the environment and harm marine life.
Plastic bags that are not properly disposed of can easily be blown or washed into rivers, reservoirs, lakes, and seas, contributing to water pollution. This is a significant issue, as water pollution jeopardizes human health and the environment. Unsafe water is responsible for more deaths each year than war and all other forms of violence combined, and it is estimated that contaminated water makes about 1 billion people ill annually.
Additionally, marine animals often mistake plastic bags for food, leading to their ingestion and the transfer of plastic up the food chain. Fish eat thousands of tons of plastic each year, and it is predicted that by 2050, there will be more plastic than fish in the sea. Plastic bags also release chemical leachates, which impair the growth of important microorganisms and contribute to the overall toxicity of the environment.
To reduce the impact of single-use plastic bags on the environment, individuals can switch to reusable bags, such as cotton bags, and support policies and initiatives that aim to reduce plastic pollution, such as plastic bag bans and the Break Free from Plastic movement.

Poor waste management
Ineffective disposal methods include open and unsanitary landfills, which can contaminate drinking water sources. In 2000, heavy rains caused a trash landslide in a massive landfill near Quezon City, Philippines, killing 218 people. Landfills are not always secure, and pollutants can leak into the surrounding earth, contaminating plants and animals.
Non-existent collection systems mean that trash ends up in natural environments, such as rivers, reservoirs, lakes, and seas, as well as on roadsides and beaches. This waste can be dangerous to wildlife and reduce economic activity in the area. For example, plastic waste on Kamilo Beach, Hawaii, has impacted tourism, the area's largest industry.
In addition to landfills, some cities incinerate or burn their garbage. While this method gets rid of trash, it can release dangerous heavy metals and chemicals into the air, contributing to air pollution.
To address poor waste management, waste minimization should be the first priority. Where waste cannot be avoided, recycling and reusing materials should be prioritized to reduce the amount of garbage that ends up in landfills, incinerators, and waterways.
