What You'll Learn
Humans would not need to wear face protection
Face masks have become a common protective measure in recent years, with many people adopting them to protect themselves from the harmful effects of air pollution. Air pollution is a complex issue, and while there is no single simple solution, face masks have been proven to be highly effective in shielding us from its adverse effects.
In a world without pollution, humans would not need to rely on face masks and other protective gear as a safeguard against poor air quality. The long list of health issues associated with air pollution, such as an increased risk of lung cancer, heart disease, and respiratory infections, would be significantly reduced. The absence of harmful pollutants in the air would mean that individuals would be free to breathe without worry, knowing that the air they inhale is clean and safe.
Currently, masks like the N95/KN95/FFP2 variants are recommended for effective protection against air pollution. These masks are designed to filter out even the smallest airborne particles, offering up to 95% filtration. However, they can be uncomfortable due to the tight fit and difficulty in breathing that some users experience. Without the presence of air pollution, people would not have to endure the discomfort and restriction of wearing these masks, especially in highly polluted areas or during outdoor activities.
Additionally, the indoor spaces where we spend a significant portion of our time would also be free from air pollutants. In our current reality, the use of face masks indoors is uncommon, and alternative solutions such as indoor air cleaners with particle-filtering capabilities are required to ensure clean air. In a pollution-free world, indoor spaces would naturally maintain good air quality, eliminating the need for such specialized equipment and the associated maintenance and costs.
Overall, in a world without pollution, humans would breathe cleaner air and enjoy improved health outcomes. The need for face protection and the associated restrictions and inconveniences would be eliminated, allowing people to live their lives freely and without the constant worry of the harmful effects of air pollution.

Less pollution, less sickness
It is difficult to imagine a world without pollution, but it is clear that reducing pollution would lead to less sickness for humans. The Earth has existed for thousands of years with natural forms of "pollution", such as fire, lead pipes, and waste. However, human activities have introduced new forms of pollution that are harmful to the environment and human health.
Climate change, largely driven by human activities, is affecting everyone and changing the way we live. The pollution we breathe in can cause various health issues, especially for children. For example, the air quality in Houston, Texas, has been affected by fires and extreme temperatures, leading to concerns about the toxic chemicals in the air and their impact on children's lungs.
Transportation is a significant contributor to pollution, with cars, planes, and boats often powered by oil, which creates pollution and harmful emissions. These emissions contribute to sickness and deaths, and the extreme temperatures caused by climate change further exacerbate health issues.
By reducing pollution, we can mitigate these health risks and create a safer environment for ourselves and future generations. This may involve shifting to alternative sources of energy and power for our vehicles and taking steps to reduce our carbon emissions.
Additionally, human activities have led to the creation of "forever chemicals" like PCBs and CFCs, which persist in the environment for long periods. Overfishing has driven some species to extinction, and plastic pollution has worsened the impacts of climate change, ocean acidification, and biodiversity loss, all of which affect human health and wellbeing.
In conclusion, less pollution would undoubtedly lead to less sickness for humans. By addressing the sources of pollution and taking proactive measures to protect our environment, we can create a healthier and more sustainable future for all.

No mass extinction
The idea that Earth has experienced five mass extinctions came from a 1982 analysis of the marine fossil record. Two palaeontologists, David Raup and Jack Sepkoski, identified five peaks of marine family extinctions that stood out against a backdrop of decreasing extinction rates through time. These events became known as the "Big Five". However, there is growing evidence that these mass extinctions did not have a significant impact on life on land.
Palaeontologist Hendrik Nowak, for example, points to fossil pollen that suggests only "short-lived disruption" from the end-Permian event, arguing that the impact was so minimal that there was no mass extinction for plants. Studies on insects and four-limbed land animals echo these findings. Spencer Lucas of the New Mexico Museum of Natural History & Science goes even further, suspecting that life on land has never experienced a mass extinction.
The distinction between marine and land extinctions is important because most of what we know about mass extinctions comes from studying marine life. It was once thought that there was little evidence of an end-Permian mass extinction of four-limbed animals (tetrapods) that lived on land. However, this was largely due to a lack of data, as land organisms are less likely to become fossils. Over the past 30 years, researchers have collected and analysed tetrapod remains from sites that capture a reasonably good fossil record of life on land during mass extinction events.
While the "Big Five" mass extinctions are well-known, it is important to note that they are not clearly defined and represent a continuum of extinction events. The impact of these events has also been questioned, with different methods of calculating extinction impact leading to other events featuring in the top five. Additionally, the idea of mass extinctions was once considered mysterious exceptions to the prevailing gradualistic view of prehistory, where slow evolutionary trends define faunal changes.
In conclusion, while mass extinctions have undoubtedly devastated ocean life, there is growing evidence that their impact on land-based ecosystems may have been overstated. This challenges the idea that the continents have witnessed five mass extinctions and has implications for how we understand the current human-induced biodiversity crisis. While human activities are driving unprecedented biodiversity loss, it is not yet clear that we are in the midst of a sixth mass extinction event.

Less waste
Reducing waste is crucial to preserving human health and well-being, and there are numerous ways to achieve this in our daily lives. One significant contributor to waste is plastic packaging, which often ends up in landfills, causing environmental harm. To address this, individuals can opt for products with minimal or recyclable packaging, such as those offered in bulk or with refillable options. Shopping bags, water bottles, tumblers, straws, and utensils can all be replaced with reusable alternatives, reducing the demand for single-use plastic items.
In our gardens and homes, we can contribute to waste reduction by selecting native plant species that require less water and fertilizer, as they are well-adapted to the local climate. This reduces the need for excessive water consumption and fertilizer use, which can be harmful when washed into nearby water bodies. Additionally, transitioning from printed materials to digital formats can significantly lower resource consumption, including water and energy, reducing our overall carbon emissions.
The fashion industry is another major contributor to waste, but individuals can make a difference by practicing upcycling. Transforming old or worn-out clothes into new, stylish items not only gives your wardrobe a unique touch but also keeps textiles out of landfills. When washing clothes, waiting for a full load, using cold water settings, and opting for air-drying or line-drying can reduce friction, minimize microfiber release, and extend the lifespan of your garments.
Lastly, our beauty routines can be made more sustainable by embracing biodegradable and vegan products free of animal by-products. Refillable containers for personal care items like shampoo bottles and sheet masks can significantly reduce waste. Using reusable bamboo cloth instead of disposable wipes and cotton balls for makeup removal is another eco-friendly option. Additionally, respecting expiration dates and fully utilizing cosmetic products before opening new ones help maximize their effectiveness while minimizing waste.
