Why do we feel the need for conservation more today than our ancestors did

We feel a greater need for conservation as, we are facing lot of risk than our ancestors. Nowadays we are wasting so much of resources than our ancestors. For example : water. We are wasting water in so many ways such as leaving running taps without closing it. Natural resources are slowly vanishing by means of people who abuse it because they do not know the limitations of it. Abusing it can cause food shortage and also cause global warming. We need to conserve resources because it is the main source of our daily needs. Remember the 3 R's- reduce, reuse and recycle. Once it would be totally vanished our life would come to an end.

Hope this helps!

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

diaria maybe go see a doctor about that
