Human Sustainability: The sustainability issue I am addressing is one of the most important issues we are facing today. This issue involves one of the most precious resources to man. We are composed of it, we require it to survive and we use it to create new things every day. I am referring to water, simple H2O. It is infact more valuable than gold or diamonds because without it we would be a long extinct species. Water Scarcity: Wikipedia defines water scarcity as, “The is the lack of sufficient available water resources to meet the demands of water usage within a region.” [1] This is a devastating problem because, as mentioned before, water is one o the most valuable resources to man. So if this resource is so important, why are there …show more content…
If one could create a similar surface then one could construct these on a larger scale to collect enough water to sustain the people living in arid environments. What is being proposed is a structure which is designed to farm or harvest the moisture out of the air. These structures could be built with the same surface as the beetles and allow us to to combat global water scarcity. There is one underlying question. Efficiency. By that I mean, if we were to mimic the surface areas of the beetles it would have to produce enough water to make the energy input worth it. So the main question to ask is; If we are to replicate the Namib Desert beetles methods of moisture collection on a larger scale would it produce enough water to make the initial investment of time, money and energy worth it? Investigation: Hypothesis: The process of moisture collection on a larger scale is a feasible idea which, in the end, will make the investment of time, money and energy worth it. Aim: To investigate whether or not moisture collection using the methods of the Namib Desert beetle can be used on a larger scale to produce enough water to make the initial investment of time, money and energy worth
After conducting the experiments, the hypothesis was found to be incorrect. The data’s common trend was; as the beetle’s mass increased, the amount of weight it could pull decreased. One of the beetles tested had a mass of 1.6 grams and was able to pull only a mass of 18.6 grams. The second beetle had a mass of 1.8 grams and was able to pull 37.3 grams.
We often hear the saying that water is the source of life so how can mankind waste this precious source that God has given us. A fine example was mentioned in the film about India’s new green agricultural system where 30 times more water is been use than the actual amount required. It is really hard to see how these farmers are spitefully wasting water when it is really needed in the neighboring communities. This goes to show that people only do things to benefit themselves not considering the needs of other people. Not only is water being wasted in developing countries but there is also water wastage in developed countries we often take our water sources for granted here in the US such as not turning off the pipes when brushing our teeth or washing our hands and the list goes on. Water conservation is the key to saving our planet because soon it will become extinct to us human beings.
The confused flour beetle, Tribolium Confusum is an organism that is approximately 4.35mm in body length and is made up of three sections, the prognathous head, rounded abdomen and a straight sided thorax, which are flat, shiny, elongated and rigid, reddish brown (Stuart M Bennett 2003). This beetle consists of two segmented antennas at the front of its body along with two small dark colored notched eyes, separated by more than three eye diameters, which allow the beetle to identify small disturbances and escape from predator (Stuart M Bennett 2003). The antenna’s consists of segments that grow from the bottom all the way till the tip, forming a club of four segments and are used to help Tribolium Confusum in sensing its surroundings (Stuart M Bennett 2003). This confused beetle has six legs; three separated equally on each side of the body, which allow it to easily maneuver through grain products. The forelegs are there for traction and the middle and hind legs are for propulsion (A Sokoloff 1972). Tribolium Confusum has well developed wings hidden under its elytra but has never been seen flying (Anon 2009). Its forewings are rigid and hind wings are membranous and folded (S.S Lal 2009).

In a similar transpiration lab, performed by an AP student, the results showed that controlled was the fastest, wind the second, light and heat the third, and humidity the slowest. These results occurred because all four environments played a role in increasing evaporation which therefore increased the rate of evaporation. In the controlled environment, the room temperature helped increase the rate of evaporation (1.67mL/m²). In the wind environment, the blowing of air on the leaves increased the rate of evaporation (0.76 mL/m²). In the light and heat environment, the heat hitting the plant increased the rate of evaporation therefore increasing amount of water being transpired (0.93 mL/m²). In the humidity environment, the moist ...
In many instances a value for the potential evapotranspiration is calculated at a close by climate station on a reference surface, conventionally short grass. This value is known as the reference evapotranspiration, and can be changed to a potential evapotranspiration by multiplying with a surface coefficient. In whatever way, this particular procedure is depend on the assumption that PET is affected only by meteorological circumstances, does not take into account the effect of vegetative density and maturity. The Thornthwaite method is known to methodically underestimate PET in more arid regions and seasons. Quantifying of the potential evapotranspiration, calculated on monthly principles, is given
Sustainability is when something can be used and not be depleted, destroyed, or damaged past recovery. As we work to live sustainably, we are in effect making use of our resources in a fashion that doesn't eliminate them, and doesn't harm their source. Our resources come from the environment around us and we need to make sure that it is not harmed as we use it. According to the EPA, sustainability stems from a single principle that "Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment” (Sustainability Information). Considering this, it's obvious why we need to make sure we live sustainably and do not damage the source of our resources, our environment.

Since development and invention takes time and money, some people question if it’s worth the effort. Some scientist are looking into another way for clean solution that doesn’t require as much funding and as much time.

Sustainability is a concept with a diverse array of meanings and definitions – a widely used glamorous, ambiguous, ambivalent and vague concept that is used by different stakeholder groups in various ways. Presumably to avoid noodling over a terminology or to avoid the confrontation with a definition, most widely the concept is broken down a planning process (c.f. e.g. Döring & Muraca, 2010). That is why most common sustainability is understood as sustainable development.1
Clean and safe drinking water resources are becoming scarce as the population grows. The world is facing many problems, but the most important thing needed to survive, is water. Water is getting low in many countries, therefore residents are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands.
One main causes of water scarcity is water mismanagement worldwide. Water mismanagement has become a crisis of governance that will impact heavily ...
Rainwater harvesting provides an independent water supply during regional water restrictions and in developed countries is often used to supplement the main supply. In times of harsh weather such as droughts and floods, it provides a fresh supply of clean water as well as in cases of mitigate flooding occurring...
