Pollution is a global environmental issue that affects everyone on Earth. It is the presence of any substance or activity that disrupts the natural environment or causes damage to the health and wellbeing of human beings.
The term pollution can be used to refer to both physical and chemical contaminants. It can also include human-made contaminants that are released by humans into the environment, such as industrial wastes or the pollutants from motor vehicles. The contamination may be in the form of liquid, gaseous or solid substances.
Air pollution, such as fine particulate matter, carbon monoxide and ozone, is a major source of illness and death for both adults and children. It can cause respiratory problems like asthma and chronic obstructive pulmonary disease (COPD/emphysema), heart disease, lung cancer and more. In addition, it can lead to premature deaths. Those most at risk for pollution are children, older adults and people with pre-existing health conditions. Pollution has outsized impacts on vulnerable communities, where industries and toxic waste sites tend to be located.
Plastics are another major source of pollution. A single kilogram of plastic generates more than 17 kilograms of CO2e in the process of production. By choosing to buy fewer products, shopping second-hand and recycling what you do purchase can help reduce this impact. You can also use less electricity and heat to reduce your CO2 emissions, and drive more efficiently and carpool when possible. The way you schedule your home deliveries and keep your vehicle in good condition can further reduce the amount of harmful gases that are emitted into the air.
