It is because your lungs will turn black. The oxygen is usually at the lungs so it is harder to get oxygen.
Most of our body cells would stop functioning after 10 minutes of lack of oxygen. If there is no oxygen in the environment, airplanes would have crashed, and mostly every vehicle that requires oxygen would stop moving. Let's say 1,000,000 years from now aliens come to our planet would ask if the humans had so much why did they disappear all of a sudden.
Oxygen was released from Precambrian rocks. cynobacteria were the first organisms to produce oxygen 2.5-3 billion years ago
About 237 years from 2011
The oxygen concentration in the atmosphere today (which is at about 21%) has been at its current level for the past 400 million years.
More than 2 billion years ago, trees and plants began producing oxygen. They do this by feeding off carbon dioxide released by living beings.
the lung capacity will lessen and the veins and tubes connecting ect will get thinner because of the tar build up therefore they can find it harder to breath because they cannot get as much oxygen to the lungs thank youu x
Due to deforestation, pollution is increasing and holes in the ozone layer are increasing.
Smoking is like a living near a chemical plant that emits toxic waste into the water. Every sip you would take, does a small amount of damage to your body. After a few years of buildup, you would end up getting sick or weak. In the same way, every cigarette you smoke damages your body. The more you smoke, the greater the damage. Because smoking reduces the amount of oxygen you get when you breathe, your skin will suffer on the outside and become wrinkled and limp looking...but more importantly your heart works harder than it has to, your lungs too...and your entire circulatory system takes a beating. Over time, it all builds up, and eventually will reduce overall quality of life (and it's preventable by NOT smoking).
Smoking X cigarettes per day for Y years to equal 150. For example, smoking three packs per day for 50 years, or ten packs per day for fifteen years would each yield a 150-pack-year smoking history.
Ten to twenty years of healthy life.
It takes 10 years for the lungs to fully recover from smoking.
over years and years,yes...but it has to be sitting, not running...and it would take a while
Yes! I have been smoking it for a few years now and back when I first started, a few hits off a joint or blunt I would be higher than a kite. Now, since I have smoked consistently for so long, I take a few hits and can barely even get a buzz. This is what causes many people to get involved in even harder drugs like pills, cocaine/crack, heroine and others.

She started smoking when she was 14 years old.
hundred years ago, travel was harder. Researching what it'd be like at your destination was harder. OTOH, getting into a country was probably easier.
