We may need GMOs to survive on Mars

We may need to get over our knee-jerk reaction to GMO crops, as they may be necessary to survive on Mars. The study of genetically modifying organisms so that they can survive on spaceships and other planets is called ‘space synthetic biology’ (1). The harsh conditions on Mars present many challenges when it comes to[…]

The price of lab-grown meat may need to drop again

The price of lab-grown meat has significantly dropped (1). In fact, the price has dropped 30,000 times in less than four years. In 2013, it cost around $325,000 to make a lab-grown burger (2). Now the cost is $11.36 or $44 a pound (3). However, as impressive as this price drop is, lab-grown meat is still[…]

The psychological effects of space travel

There are many challenges associated with long-duration space travel. There are factors, other than the technological and physiological obstacles, that will determine whether the trip to Mars is a successful one. There are a number of behavioural issues that could affect crew members during the two- or three-year round-trip to Mars (1). The psychological effects[…]

Here’s how home bug farms promote sustainability

One of the great challenges of the 21st century is following a diet that provides us with the many nutrients we need for health, but that is also affordable and sustainable. Home bug farms may help to provide people with exactly these benefits. A government report published in 2011 defined sustainability as:   “A system or[…]

Weekday vegetarian flexitarian

Great conversation opener: ‘I’m a weekday vegetarian flexitarian’. ‘A what?’ Try that, see what response you’ll get. And even better, actually become a weekday vegetarian flexitarian. I think the concept of a weekday vegetarian is easy enough to understand, you’re a vegetarian Monday to Friday, and a carnivore on weekends. ‘Flexitarian’ can be more confusing, cause[…]

Producing sustainable food with aquaponics

Food production is not sustainable (1). Agriculture uses 38% of the world’s total land area and is responsible for 70% of global freshwater consumption. This has prompted some commentators to argue that in order to promote sustainability we need to change how we behave. Other experts are more focused on technological innovations, such as aquaponics.[…]

Colonising planets other than Mars

Right now the goal of SpaceX is to colonise Mars. This is the nearest planet that we could feasibly travel to and inhabit. Soon our technological capabilities will allow us to travel to, and live on, the red planet in a cost-efficient and sustainable way. It will be science fiction made reality (1). But there is[…]

Food scarcity is set to worsen, but here’s what we can do about it

The global population is set to reach 9.7 billion by 2050, with most of the growth taking place in developing countries (1). The United States Department of Agriculture says the number of hungry (‘food insecure’) people in sub-Saharan Africa will rise by a third (2). In order to tackle the issue of food scarcity, the FAO claims[…]

Terraforming Mars: How to live sustainably on the red planet

Terraforming Mars involves changing the surface and climate of the planet to make large areas hospitable to humans. There are many reasons why permanent human habitation on Mars is being planned for: population growth, demand for resources, and runaway climate change. Of course, if and when we terraform Mars, it would be ludicrous to repeat[…]

Becoming a weekday vegetarian

Weekday vegetarian, some people get angry when they hear this phrase. Why? I don’t really know or understand, but I’m guessing it’s because they see life as a 0-1 kind of situation, it’s either black or white. You can’t be a vegetarian and a carnivore at the same time. Or can you? Life isn’t black[…]
