Immanuel Kant was a German philosopher who is now famous for his concept of the ‘categorical imperative’. Similar to the ‘golden rule’ found in many religions (do unto others as you would have them do unto you), the categorical imperative works as a kind of handbook for determining whether an action is moral or immoral. In this piece, I’ll be looking at some lifestyle decisions which are relevant to climate change through the lens of this rule to find out what Kant might have thought about climate action.
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.
In recent years, study after study have confirmed our worst fears about climate change and the window for effective action is rapidly closing. Many people now find themselves scrambling to come to terms with the complexities of climate change. Here are 3 things you should know:
A report released in 2017 found that over half of all global emissions since 1988 have been produced by just 25 companies. When you take into account the 100 most environmentally damaging companies, known as the ‘Carbon Majors’, that figure rises to over 70%. Even so, we are constantly told that individual actions like using canvas bags and taking the bus will be enough to avoid the catastrophic effects of climate change. The truth is that the onus is on the major greenhouse gas emitters like Exxon Mobil and Shell Oil to simply stop extracting and distributing fossil fuels. Unfortunately, the pressures of the competitive market mean that they are not going to do this without a push.
Humans have been using biofuels for as long as we’ve been using wood to fuel our fires. In the last hundred or so years, however, we’ve begun to understand how plant matter can be converted into liquid fuels that could soon power a plane. In this piece, I’ll be looking at where biofuels are now and where they need to be if they are to significantly reduce CO2 emissions.
