According to NASA, the human being requires about 830g of air a day which is roughly one large balloon and 4000-5000 calories of food intake a day which amounts to 800g of dry mass. Ah ok so I was thinking... I go to work each day on the tube and near the end of my journey which takes probably on average 40 minutes, I get really tired and even more so on the journey back home. I'm thinking that this is because the amount of Carbon Dioxide reaches a point where there is more of it than air in the carriages. Pretty scary thought if I'm right but anyway, breathing in the gas causes us to feel sleepy and I wondered what if we had this ballon(which may not be 830g as that seems too small?) and used that instead of the co2 how much awake we'd be. Ok, granted a stupid thought...but a thought non the less!
With all these resource calculations, this brings me to my next few thoughts.
In 2050 there will be 9 billion people. That's according to David Attenborough. The world is producing more people than that which the earth can sustain. We already cultivate as much as we can. Large countries are buying land in Africa to grow food(another story) and since the 1800's our population has creased exponentially as we've overcomes diseases with medical advances. Another issue: Water. We've only got a finite amount of water and as we demand more and more, it'll become less available. Water doesn't go away, it just becomes unavailable as we consume it - the same amount of water is on the earth as there was when the earth began. Interesting. That said, drought is an increasing problem in Africa and recently Texas is having a torrid tine due to the worst drought in years.
Pollution and greenhouse affect our natural world and if there is one thing that sustains growth and the Hunan being is the food it needs and gets from agriculture. With space at q premium and couple that with our destruction of the natural world, sustaining the worlds human population becomes a real problem. We've not talked about how all these human problems affect the animals but that's another story.
Although, what does this mean for the man on the street? Should I buy a car or not. Should I have children? How many. These are questions that are taboo but are a reality but still ignored. I think if we had to continue at the rate we are going, then look back at the consequences, it'd be plain to see that the only conclusion that could be realised is that humans don't care about the earth. Plain as day.
Can we do anything about it? No not really. We can try but as humans we are a team, a social collective and it's this collective team that doesn't Care about the earth. Remember I'm talking about billions of people here, not the NGOs or minority human groups who are interested at our conservation on earth.
The huge problem is that the uneducated people in the world produce more offspring than all other groups, so as an educated person a choice not to buy a car or have children may not have an impact if everyone else will just do it for you, then do it in excess. Obviously the argument there is that as educated people, it's our obligation to educate those that aren't educated and obviously knowing the problems not make them worse anyway . In this way you and me can make a difference.
Maybe the survival of the human being is overcoming our own ability and knowing when to stop. That is very very difficult because as a race we are progressive and will continue to move forward and forward not worrying about what we trample on.
