18 December 2022 (UN News)* — Humanity faces unprecedented engineering challenges if it is to survive. Solutions to these challenges are waiting to be discovered in plants, animals, and microbes, but these are lost forever, if we do not preserve the rich diversity of life on Earth.
But all life forms are unique and must have the right to thrive, with or without dubious benefits to humans.

UNDP: Nature has inspired a wide range of engineering solutions
The UN biodiversity conference, COP15, is due to wrap up on 19 December. This weekend, we are looking at some of the ways that humanity is reliant on biodiversity for a healthy and thriving global ecosystem.
When a species goes extinct, it takes with it all of the physical, chemical, biological, and behavioural attributes that have been selected for that species, after having been tested and re-tested in countless evolutionary experiments over many thousands, and perhaps millions, of years of evolution.
These include designs for heating, cooling, and ventilation; for being able to move most effectively and efficiently through water or air; for producing and storing energy; for making the strongest, lightest, most biodegradable and recyclable materials; and for many, many other functions essential for life.
Nature’s value is not limited to human applications, but the loss of nature and biodiversity represents major losses to human potential as well.
Here are some examples of the ways that nature has inspired engineering solutions.

Way of the dragonfly
Inspired by the energy efficiency of dragonfly wings, particularly at low wind speeds, Professor Akira Obata, formerly from Japan’s Nippon Bunri University, designed corrugated blades for micro-wind turbines that turn and generate electricity, at wind speeds as low as 3 kph.
Most wind turbines perform poorly when speeds are less than 10 kph; some will not turn at all. By lowering the minimum wind speed requirements, these micro-wind turbines can harness wind energy in easily accessible locations like rooftops and balconies, and not need expensive towers to capture the higher speed winds found at higher elevations.
By studying and understanding the aerodynamics of dragonfly flight, Obata was able to make inexpensive, lightweight, stable, and efficient micro-wind turbines that can be used in off-grid locations in developing countries.
