If you walk at night along an open marsh or riverbank, you may well come across an incredible animal. This mammal with two arms and two legs is agile enough to chase and catch a fish underwater and smart enough to use tools. There are as many as 13 distinct species of otter, but I will be focusing on two: the sea otter and the Eurasian river otter. Sea otters recently captured the hearts of millions when they were featured on David Attenborough’s Our Planet. In this piece, I will be looking at what makes otters so special, and what makes them so damn endearing.
Ireland’s carbon footprint is an unusual one. At 34% of the total national emissions, agriculture has a greater impact on our emissions profile than any other European country. For comparison, waste (which includes the footprint of all our plastic) is responsible for just 1.5% of our emissions. Even so, it seems like businesses and well-meaning citizens are far more concerned with ditching plastic straws than they are with reducing the footprint of the foods that we eat.
Hello and welcome to Carbon Neutral Lent! This year, CNL is joining forces with Preserve Ireland and Small Change to bring you a series of podcasts, blog posts, resources and events that will help you to measure your carbon footprint this lent and find out which areas you can improve on. Each week, we’ll be covering a topic like ‘transport’ or ‘food’ and identifying which options are best or worst for the climate. Below is a free downloadable tool created by CNL’s Darragh Wynne which will help you keep track of your carbon in a way that is detailed enough to be accurate, but still simple enough to be doable.
How do we solve climate change? Do we eat less meat? Turn off the lights? Fly less? ‘No!’, I hear you say, ‘we need systemic action!’ To a large extent this is true, but as with all things related to climate change, it is not quite so simple. In this piece, I will be playing devil’s advocate and putting forward some of the arguments for why individual action is also important. Please do not take this to mean that I am a puppet of the corporations.
Bogs and Irish culture have been intimately linked for centuries, cropping up in everything from our traditional songs to the work of our most beloved poets. They have provided us with energy, clean water, jobs and a home for our wildlife. Globally, degraded peatlands account for a quarter of all carbon emissions from the land-use sector despite covering only 3% of the land. They also contain 30% of the world’s soil carbon; that’s twice as much carbon as is stored in all the world’s forests. It is estimated that more than 80% of Irish peatlands have been damaged in some way.
Printers, microwaves, chargers, DVD players, desktop computers and many other devices all drain energy when turned off or not in use. This drain is known as ‘vampire’ or ‘standby’ power and is responsible for a huge amount of energy loss each year. Since that energy is largely generated by burning fossil fuels, vampire power accelerates the rate of global warming as well as raising your electricity bill.
New research has shown that it may be possible for us to convert methane into fuel cheaply, quickly and on a large scale. The key to this energy revolution will be exploiting a type of bacteria known as methanotrophs. Methanotrophs are incredibly abundant in nature. They account for 8% of all heterotrophs on earth (organisms like us that have to ‘eat’ rather than photosynthesising their food). These incredible bacteria are capable of converting methane into methanol very easily, a process that has been referred to as the holy grail of modern chemistry. If we could perform this conversion as easily as methanotrophs, we could seriously cut down our GHG emissions.
Some renewable technologies harness the vast mechanical power available from a planet that is in constant motion. Wave power generators (WPGs) are a possible energy source of the future, but how do they compare with their rivals?
All ecosystems are fragile and vulnerable to devastating chain reactions. By reducing the diversity of the plants on your lawn, you greatly reduce the hospitability of that environment for insects like bees, beetles and butterflies. This, in turn, has an effect on the food supply available to birds and small mammals. On top of all this, most of us cut the grass with either petrol-powered or electric mowers, both of which hasten and intensify climate change, the greatest threat currently facing people and animals alike.
