One thing that will help to support the demand for healthy, accessible food while reducing the impact on the environment is the Blue Revolution. This is a movement aiming to drastically increase aquaculture* production, help alleviate the pressure on the oceans ecosystem and provide sustainable seafood for millions.

*Note: Aquaculture is the breeding, rearing, and harvesting of fish, shellfish, algae, and other organisms in all types of water environments

In this post we’ll cover how the Blue Revolution started, why it’s important, and what you can do to help join the movement. 

How did the Blue Revolution Begin?

Before we talk about the Blue Revolution, let’s review the Green Revolution. This period (during the 1960s and 1970s) was characterized by a large advancement in global agricultural practices which helped to massively increase the grain-based food supply. The use of modern technology and methods such as such high yielding variety (HYV) seeds, tractors, irrigation facilities, pesticides, and fertilizer made this revolution possible. 

Subsequently, the Blue Revolution signifies the emergence of aquaculture as the newest and increasingly most important practice to improve the food supply.

Before the 1980s, food supply from aquaculture was sparse. However, as time went on, overfishing increased, leaving our oceans depleted. The idea of aquaculture presented a unique way to stabilize food supply without further ruining the ocean. Per the State of World Fisheries and Aquaculture Report, aquaculture has been the fastest growing food production sector in the world since 2000. Currently, farmed seafood products represent over 50% of all seafood production.

Do you sometimes feel full of energy on a bright sunny morning? The major reason for this is the blue light emitted by the sun.

You probably reach for your smartphone or computer when you get to bed. Unfortunately, these devices screens emit blue light, which interferes with your natural sleep cycles. Reducing light exposure in the evening, especially blue light, is essential in helping your body prepare for sleep naturally.

How Does Blue Light Affect Sleep?

Your eyes cannot efficiently block blue light. Therefore, almost all the blue light passes directly to the rear of your retina. This helps your brain decode light as images.

When your eyes are exposed to numerous light colors, it controls your circadian rhythm or sleep-wake cycle. Blue light affects the eyes more than other colors as it messes with your ability to get ready for sleep. It blocks melatonin, the hormone that makes you sleepy.

If you are unaware, here are some sources of blue light you might encounter:

• Computer monitors
• Fluorescent light bulbs
• Gaming systems
• LED bulbs
• Smartphones
• Tablets
• Televisions

How To Minimize The Effects Of Blue Light On Your Eyes

Blue light blocking glasses: These types of glasses are designed to protect your eyes by filtering out HEV blue light. You can purchase prescription blue light glasses or non-prescription blue light glasses. The glasses reduce digital eye strain and make your screen time much more comfortable.

Limit screen exposure an hour before bedtime: This is like a technology curfew where you stash away all electronic devices at least an hour before you go to bed. Engage in other activities to help you wind down, such as simple exercises, working on a puzzle, or reading a book.

Change your device settings: If it is not practical to put your laptop or smartphone away, you can change the settings on the device. Set them to ‘dark mode,’ ‘night mode,’ or any other option that reduces their screen brightness. This is a small change that helps reduce exposure to blue light.

Change light bulbs: Light-emitting diode (LED) bulbs produce more blue light than fluorescent ones. So, change your light bulbs if you are using LED bulbs instead of fluorescent bulbs as they give off less blue light.

Blue light filtering apps: Install these apps on your computer, tablet and smartphone screens. They are efficient as they filter most blue light and prevent it from reaching your eyes without affecting the screen display.

Get sufficient exposure to light during the day: Begin your day with bright light or sunlight to help enhance alertness and wakefulness. Do not worry if you have to work indoors full-time. You can place your computer near the window when it’s sunny, and you will reap blue light benefits in the daytime.

Even on a cloudy day, strive to obtain some outdoor light, which is more than you would get from your computer screen. Some people look for a lightbox on cloudy days or during winter. When getting a lightbox, choose one with a broad light spectrum: 2,500-10,000 lux.
