We are made aware almost daily of the dire impacts of biodiversity loss and climate change. It can be overwhelming, but the good news is that there are simple things we can do in our daily lives that can make a real difference. And Earth Day is the perfect time to consider taking a couple of small steps. I've had the good fortune to travel the world with my brother making documentaries about the environment for more than four years, and here are just a few tips that we've picked up, and you can consider adopting them too.
Driven by the taste for shark fin soup, long line fisherman around the world are eliminating some 100 million sharks per year -- a reduction, in some cases of 90 per cent of the species. Sharks, being apex predators, breed very slowly. The inevitable result of all that fishing is a complete extinction of many shark species within the next ten years according to Sharkwater.com.
Improving the way we fish and grow seafood is critical to the survival of some of our planet's most threatened marine and freshwater species and environments. But a national sustainable seafood day is also a critical reminder that even through our everyday choices in what food we buy, we can have a profound impact on the future of life on our planet. And nowhere is that more true than at our fish counters.
