Differences between surrounding and humans

Therefore, using the concept above, the process of air purification can be emulated from green plants as air pollution is a prevalent issue that needs to be addressed, especially indoors. Biomimicry in the form of an air purifier can be used to 'clean' the air we breathe, thus helping us to address air pollution in indoor environments.

The incoming light enters the front of the eye, passes through the transparent innards of the eye, and enters the retina. At this stage, the light will register if it hits a rod. In the human eye, if it misses, the light is absorbed in a black layer behind the retina and is gone forever. But in the cat eye, if the light has not hit a rod, it will reflect off the mirror layer and be bounced. The light now has a second chance to hit a rod, and to be put to work.

From the points mentioned above, it can be clearly seen that bamboo chopsticks are more sustainable than wooden and plastic chopsticks. Concerning the ethical implications, I believe that bamboo chopsticks are much better compared to their previous counterparts. Bamboo chopsticks are not only environmentally friendly but are better options for our health compared to wood and plastic chopsticks.

On the other hand, plastic chairs also have various benefits.

As discussed above, both wooden and plastic chairs have their respective sets of advantages and disadvantages. When it comes to sustainability and ethical implications, however, the answer might not be really straightforward and much depends on the source of the materials. The use of plastics is heavily criticized nowadays but the criticism really only applies to single-use plastics. Plastic furniture lasts for many years so doesn’t have the same negative environmental impact, so it is a purchase that can be made with a clear conscience. Using wood does mean cutting down trees, but using timber from a sustainable source means there are also no environmental concerns. Therefore, it really depends on the source of the materials used in the construction of the chairs for them to be sustainable. In my opinion, a wooden chair is a more eco-friendly option compared to plastic chairs as a wooden chair will last much more longer compared to a plastic chair if maintained properly. Instead of consuming more and more plastic chairs, it is better to have one wooden chair which is durable and long-lasting when properly maintained.
