Air - more than what you breathe

Air is one of the indispensable things which not just humans, but mostly all the organisms can't replace to live everyday lives. We benefit from air in many different occasions.

Organisms' lives
First of all, most organisms require air for their survival. Most animals require oxygen for respiration. Respiration is when you get rid of unnecessary gases in your body such as co2 and water vapour, and breathing in oxygen. Scientists have discovered single-celled organisms which do not require oxygen, but if air wasn't present it wouldn't have been created anyway.
Plants require co2 for their photosynthesis, which is process for plants to make their own food.

Power generator
Air is a renewable resource and humans have taken the advantage of that. Humans developed things such as windmills and wind turbines, which converts moving air (wind energy) to electrical energy to create power environmentally friendly.

Different sports
Humans take advantage of air and use them to play different types of sports. Sports such as windsurfing, kite surfing and sailing all require wind energy to play. Also, activities such as ski diving use air (resistance) when using the parachute.

Compressed air (pneumatic)
Engineers use compressed air, or pneumatic system. Pneumatic system is using air under pressure, or electrically in cylinders and air motors. It's a cheaper and more flexible system and it's also used in construction, medic and other areas.

To conclude my blog, you've seen many uses and advantages about air, which we have full responsibility and we should look after our precious air in high respect.
