For sure. Waiting at the doctor’s office or travelling long distance was so boring before smart phones.

It got shot down. Not sure why news say “crashed”…

Just flip it, the top bars are for measuring from the inside.

For fun, a rough estimate is 20% of an animal’s mass in carbon. A cow is around 600kg (1000 pounds). That means 120kg of carbon. Carbon being 12g per mols, that is 10’000 mols of carbon. Turn that all in CO2, that makes 10’000 mols of CO2 which is 44g per mols, so 440 kg of CO2.

As methane (CH4), it is instead (16g per mols) : 160kg.

A cow produces 100kg of methane a year so a cow’s biomass is not sufficient to compensate for it’s methane production over its life.

Plus, when you eat the cow, you are the one farting that carbon back in the athmosphere anyway.

Still, cattle is 10% of the global greenhouse gas emissions.

If we can get nuclear fusion to work, that would be the kind of things that would then make sense to do. I can only hope that we figure it out as soon as possible.

Cows do not create carbon. They turn it into methane which is a worse form of carbon.

The same way you can turn carbon in biomass to “lock” it from the atmosphere, you can turn it in worse forms of gas that cause even more heating like methane. The methane will turn back in CO2 form once it burns or degrade naturally (a dozen years or so) but while it is under methane form, it will make it worse, accelerating the heating effects. But even stopping all methane emissions is only a temporary solution as carbon from pool 2 keeps moving in pool 1. It may give us more time before reaching the same level of greenhouse effect but we will reach it anyway.

Breathing does not create Carbon, it is only transformed.

There are basically 2 pools of carbon. The carbon already in circulation in the athmosphere, plants, animals and so on, roaming at the surface. That Carbon can be CO2, or other mollecules, but there is always a fixed amount. You breathing is simply borrowing the carbon for a bit and putting it out again in the air when exhaling.

The second pool is carbon locked away in the ground, as coal, oil and whatnot. That carbon is OLD and is not supposed to be in the first pool. When you burn oil, the carbon from the 2nd pool ends up in the 1st one. You cannot really offset it because even planting trees just transforms it as wood for a bit, but if the tree burns or rots, the carbon goes back in the air. The only option long term is to send the carbon back in a locked state in the second pool.

But for you, just reduce the amount of carbon you move from pool 2 to pool 1 to help the earth. Cut on oil, gas, coal as much as you can. The rest is basically irrelevant.

You can compare it to the water cycle. You are at a lake with a pump, and pump the water from the lake back into the lake. You can keep going forever and will not cause the lakes to rise since the water is pumped from there anyway. BUT, if a mega corporation starts pumping from underground sources and dumping it in that lake, it would overflow for sure. And they would blame you for all the water you are pumping.

You gotta double it until it overflows to negatives, then you end up reviving billions of people!

Fair enough, but the difference is not that much considering that you have to charge your phone more often if you stop halfway. Plus, devices are so power hungry these days, you need that extra % to last the day sometimes. Still, we can all agree that batteries will fail and should be swappable. They can be recycled almost in full. EU is doing good on this one.

Not on modern-ish devices. The battery controller already does it for you and shows you 100% when it is not physically at 100%. Plus, lithium polymer batteries are not as affected by this issue as older battery types. This is an old myth basically.

What a blast from the past. Yeah they were called Demotivational posters.
