Of course, here are seven things that aren't as natural as they might seem at first glance:

1. **Processed Foods:** Although many processed foods contain natural ingredients, the manufacturing process often involves the addition of preservatives, colors, and other chemicals that do not naturally occur in the food.

2. **Cities and Urbanization:** While humans have lived in communities for thousands of years, the development of modern cities and mass urbanization are relatively recent phenomena in historical terms and are not inherently natural.

3. **Digital Technology:** The widespread use of electronic devices and the internet are the result of technological advances that have only emerged in recent decades, and are not natural phenomena, but rather products of human ingenuity.

4. **Anthropogenic Climate Change:** Although climate change is part of Earth's natural processes, human activities such as the burning of fossil fuels and deforestation have significantly accelerated these changes, making them much faster than they would have been naturally.

5. **Synthetic Clothing:** Materials such as polyester and nylon are synthetic and do not occur naturally. While they may be derived from natural products such as petroleum or coal, the manufacturing process and resulting materials are not natural.

6. **Advanced Medicines and Medical Treatments:** While many medicines have their roots in natural substances, the synthesis and development of modern medicines involve highly complex and technologically advanced processes that are not found in nature.

7. **Man-Made Constructions:** From skyscrapers to bridges, many human structures do not occur naturally and require elaborate engineering designs and man-made materials to build.
