Laughing gas…does the earth make it laugh or make it cry?

Laughing gas.. Does the Earth make it laugh or make it cry?

Imagine that there is laughing gas in dental clinics, and the planet is plunged – at the same time – into climate nightmares! Yes, we are talking about nitrous oxide (N2O), known as “laughing gas”, a gas that may seem cute and funny in the operating room, but it has the destructive power that makes the earth cry under the weight of global warming.

How can this gas become the focus of a global environmental dilemma? This is what you will discover with Earth Guards in this article; So read on to learn how nitrous oxide moves from doctors’ tools to our farms, and from there to the atmosphere. Eventually turning into one of the most dangerous enemies of the environment.

Emissions Gap

Before we address the issue of nitrous oxide, we should point out here that there is a gap in emissions rates worldwide. Recent statistics conducted byUnited Nations Environment Programreveal a clear imbalance in the distribution of carbon emissions among the countries of the world, as the per capita share in the Russian Federation and the United States, for example, exceeds the global average of 6.5 tons of carbon dioxide equivalent, while the per capita share in India is less than half of this average.

The same applies to Brazil and Indonesia, where their per capita income is close to the global average of the G20 countries, which is 7.9 tons. While the per capita share in the least developed countries is only about 2.2 tons, the per capita share in small island developing states reaches 4.2 tons.

The scope of this gap expands to include emissions resulting from consumption – whether between countries or within them – as data shows that 10% of the world’s population – those with high wages – are responsible for 48% of total emissions, while half of the world’s population – those with low wages – participate in these global emissions at a rate that does not exceed 12%; Which confirms our need for fair policies, in order to address this gap between countries, in accordance with climate justice.

Nitrous oxide is a climate challenge

Nitrous oxide is known for its ability to heat the Earth at a rate that is approximately 270 times greater than the effect of carbon dioxide – according to data from the Food and Agriculture Organization – as this gas remains in the atmosphere for a long time, up to 114 years. Which allows it to react, turning into nitrogen oxides, which weaken the ozone layer. Therefore, the Earth’s exposure to harmful solar rays increases, and this affects agriculture in general and human health in particular.

Approximately 60% – approximately – of nitrous oxide emissions worldwide – according to data from the Institute of Environmental and Energy Studies in the United States of America – occur naturally, while the remaining percentage – 40% – is due to human activities. These emissions are increasing at rates more than ever before. Nitrous oxide emissions rates from 2020 to 2021 were higher than their average annual growth rate – globally – over the past ten years.

Agriculture is a major source of emissions

According to the Global Nitrous Oxide Budget Report, agriculture is a major source of emissions of this harmful gas. Despite the role of nitrogen fertilizers in improving crop productivity – by providing nutrients to plants – half of the added amount is absorbed by plants, while the rest seeps into groundwater, or is released into the atmosphere in the form of gases. This nitrogen is consumed by bacteria; Which leads to the production of nitrous oxide, which is one of the powerful Greenhouse Gases (GHGs) that contribute to global warming.

Nitrous Oxide Emissions Treatment Technologies

Despite the negative impact of nitrous oxide emissions, there are innovative techniques to mitigate this problem. For example, remote sensors may be used to accurately detect nitrogen gas levels in real time. This allows optimal control of the use of fertilizers and reduces their waste. Nitrification inhibitors are also used to reduce the activity of bacteria that produce nitrous oxide. Which reduces the amount of gas emitted into the environment.

Solutions to enhance agricultural sustainability

In recent years, research has been conducted to discover environmentally friendly agricultural methods, based on improving irrigation and fertilization practices. To reduce the environmental impact of agriculture. To reduce nitrous oxide emissions and ensure the sustainability of the agricultural sector, several solutions can be adopted: Among them: expanding the use of organic fertilizers, and farmers can also be encouraged to adopt precision agriculture techniques, which rely on real-time data. In order to improve the use of agricultural resources. In addition to the above, we must support research and development in the field of improving fertilizer efficiency. We must also enhance methods of environmental awareness among farmers and provide them with economic incentives. To adopt more sustainable agricultural practices.

In the end, nitrous oxide is not just an emissions problem. It is one of the main factors that increases the impact of the climate change crisis, as it directly contributes to increasing global warming. Therefore, we must enhance global awareness of its disastrous effects, and move to clean energy sources.

For all of this,Earth Guards believes that practical steps must be taken in this environmental issue; In order to ensure a more sustainable future for us and future generations, which is something that “Egypt Vision 2030” is very concerned with, through its axes of reducing pollution. So that this will permanently benefit the lives of Egyptians.
