Carbon Neutral Lent: Week 1 – Food

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.

For Peat’s Sake: Bogs, Bord na Móna and the Climate

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.

Short Change: Artificial Visionaries

Researchers at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are investigating the possibility of partially restoring sight to the blind by using a device known as an optic nerve implant (ONI). The device works by bypassing the eyeball and sending electrical signals directly to the optic nerve, the pathway through which visual information reaches the brain.

The New Frontier: Plastic Pollution in the Ocean

Every minute, the equivalent of a truckload of plastic enters the sea. Since 2004, humans have produced more plastic than we did in the previous 50 years combined. As the global population rises, our need for cheap and sturdy materials rises with it. The problem with plastics is that they are too sturdy. Every piece of plastic ever produced still exists somewhere in the world. Once the plastic has finally disintegrated, that is by no means the end of the problem. Plastics in the ocean break down into tiny particles known as microplastics. Such particles are found throughout marine ecosystems; from the stomachs of fish, to the stomachs of the seabirds who eat them.

Gene Genie: The Scientist who Jumped the Gun on Gene Editing

Hence, geneticists worldwide have called for a moratorium on human germline trials. Critics say that gene editing technology has not yet been developed or tested sufficiently for use on human embryos. We simply do not yet know the long-term effects of genetic modification using CRISPR.

Opting Out- The Future of Organ Donation

Despite both the effectiveness of the treatment and the general public support for organ donation, there is a persistent global shortage of transplantable organs. In recent years, governments and regulatory bodies have been exploring a variety of ways to decrease this shortage, potentially saving hundreds of thousands of lives. This article summarises the most significant regulatory and technological developments around the world and evaluates their effectiveness in increasing the availability of transplantable organs, focussing on the move from an ‘opt-in’ to an ‘opt-out’ system.

The Powers that Bee: The Fight to Ban Neonics

Back in February, the European Food Safety Authority (EFSA) released an updated report on the harmful effects of certain pesticides on a variety of bees. Confirming conclusions made in their 2013 report, the EFSA found a wealth of evidence supporting the claim that the world’s most popular pesticide group, neonicotinoids (or neonics for short) are harmful to both honeybees and bumblebees.
