seaweed is sustainable.

sustainable shopping, for eco friendly brands and products good for the environment

Overall, is seaweed eco friendly? Is seaweed sustainable?

Seaweed production is relatively sustainable since there is no known significant damage to air, water, land, soil, forests, etc. Be sure to buy non GMO/organic, as toxic, chemical pesticides contaminate air, water, soil, etc. when using regenerative practices.

A 2018 Oxford University study – which is the most comprehensive analysis to date of the damage farming does to the planet – found that ‘avoiding meat and dairy is the single biggest way to reduce your impact on Earth’ as animal farming provides just 18% of calories but takes up 83% of our farmland.

Consuming animal products and byproducts is not environmentally friendly and is one of the worst things for the Earth. Not only is meat production wasteful, it causes enormous amounts of pollution. The industry is one of the biggest causes of climate change.

seaweed is vegan. seaweed benefits include not killing, harming or using animals.

seafood and fish is not vegan

Is seaweed vegan?

Yes, seaweed is vegan. Seaweed is a marine algae, or sea vegetables and not an animal product or byproduct, therefore making it a vegan food. 

Animals of factory farming are suffering. They live in horrific conditions that often include confinement, physical abuse and unnatural environments…so much so that they need to receive antibiotics to keep from getting ill or spreading disease. Growth hormones allow all kinds of animals to become fatter faster and live short lives.

Because we cannot see for ourselves how these animals live and what they endure does not mean it isn’t happening. The meat, poultry and dairy industries do everything they can to distance us from knowing how our food comes to be in order to keep us in the dark about what we support each time we buy animal derived products and byproducts.

Go vegan for animals!

It’s the best way to help animals and it’s not as difficult as you may think. Speak for animals with your actions, for they cannot speak at all.

seaweed is a product that may or may not have labor issues.

benefits of buying fair trade, labor rights, human rights and workers rights issues

Is seaweed a product with laborer concerns?

At this time there are no major concerns with seaweed production but that doesn’t mean it isn’t happening!

It’s important to stay aware of human rights concerns and worker exploitation that may come with specific brands.

Did you know the single largest employer in the world is agriculture? The labor involved behind each and every product cannot go unrecognized. 

Some known problems include workplace health and safety, child labor, gender inequality, inadequate pay, wage theft and exploitation. Workers can even experience harassment, humiliation and violence and unfair employers often fail to provide laborers with access to shade, drinking water, restrooms and breaks. Consequently, laborers can face nausea, dizziness, heat exhaustion, dehydration and heat stroke -the leading cause of farmworker death! 

Such mistreatment is like modern day slavery. Workers are often afraid to report issues because they fear it will result in losing their jobs or deportation. 

We can improve people’s lives with foods we eat every day simply by buying products that are certified fair trade.
