Per yearOn the Saturday of the last week of March, bothEarth Hour-Earth Hour, have you turned off the lights this year?
This energy-saving activity initiated by the World Wide Fund for Nature (WWF) advocates that people around the worldearth day nightLights off for one hour from XNUMX:XNUMX to XNUMX:XNUMXTo save energy and reduce consumption.
The reason for this activity is that in recent years, the rate of global warming has been faster than at any time in history.
I believe everyone has paid attention to these signals of global warming: rising sea levels, melting ice in the Arctic and Antarctic, frequent extreme weather...
So how are the greenhouse gases that cause global warming produced?In addition to common fuels for power generation and heating, deforestation, and use of transportation, it actually includeslivestock activities.
In layman's terms:
Cow fartIs the culprit that causes global warming!(Noichi)
Lamb: What?It's none of my business?
The reason the farts of these seemingly harmless herbivores are so deadly is becauseRuminate(chu).
The so-called rumination is to return the eaten food to the mouth and eat it again.
It may sound gross, but cows, sheep, goats, deer, etc. are all ruminants. Most of them have four stomachs, and rumination can make food easier to digest.
In their stomachs, there are more than XNUMX kinds of microorganisms that help digestion.And some of these microbes produce methane gas as they break down food.
Methane gas accumulates in their intestines and must be expelled by belching or farting, which is the same principle that we fart when we eat too many beans.
As early as 2006, the Food and Agriculture Organization of the United Nations proposed that the livestock industry produces 18% more greenhouse gas emissions than the transportation industry.This is not surprising at all, after all, the farts of cattle and sheep—that is,Methane has a global warming potential (GWP) more than 80 times that of carbon dioxide!
Speaking of this, I have to mention New Zealand, the country with the largest sheep population.
Greenhouse gases emitted by cattle and sheep in New Zealand,accounted for half of the country's emissions...It is indeed a place where everyone can own a few sheep on average.
In order to address excessive emissions without harming the domestic livestock industry, New Zealand has decided to:Breed sheep with less farts!
The specific method is: lock the sheep in the "fart room", monitor the amount of fart of the sheep, and select the sheep with less fart to cultivate the next generation.
Sheep: You humans are too outrageous!
Over the years, the New Zealand government has repeatedly proposedLevy a "fart tax"proposals, but they were all dropped due to strong protests from farmers.
It seems that the road to emission reduction is long, and we have to continue to explore...
Who would have thought that the farts of these lamb kebabs and small fat beef rolls could be so powerful!
It was also suggested that:Why not collect the farts of cattle and sheep as energy?(Maybe scientists are already working on it)
And the team leader just wants to know: Will the lamb with less fart taste better...
Seriously, seeing the climate issues that have attracted attention in recent years, people should also realize that energy conservation and emission reduction are urgent.
At XNUMX:XNUMX tonight, turn off the lights, put down your cell phone, and go to see the twinkling stars in the night sky
