Land-based farming has an enormous impact on our oceans, marine life and ocean-based farming. A scary 80% of marine pollution comes from land-based activities like oil leaks, toxic chemical and fertiliser runoffs and garbage that is carelessly or not properly discarded and recycled. This is an incredibly sad figure which has devasting effects as these factors destroy and disrupt marine life. This throws the entire oceanic food chain out of balance which has a domino effect on the entire food chain, of which we are a massive part. This means all the pollution that we like to think doesn't have any effect on us, finds its way back to our plates whenever we eat anything that is from the ocean, like fish, seaweed and even fish sauce.
