10 reasons why seaweed farms are both sustainable and practical:
- Seaweed farms require no land.
- Seaweed farms are quite efficient, and can be harvested for commercial use within 90 days.
- Seaweed farms by-pass negative side-effects like deforestation or pesticide-use.
- Seaweed farms work in harmony with surrounding wildlife.
- Seaweed farms don't interfere with boats or ships, and create economic opportunities where none exist.
- Harvesting seaweed requires very little biofuel; it is a scalable process.
- Seaweed has multiple uses: it can produce both food and fuel.
- Seaweed is biodegradable, unlike solar panels and wind turbines that require heavy metals and create waste.
- Seaweed yields 30x more energy per acre than biofuel land crops like soy or corn.
- Only 2% of the fertile ocean is covered by kelp forests, so there is much more room to grow.

What's the situation? A stricken ship has leaked over 1,000 tons of oil over the coast of Mauritius. Experts fear that the ship may soon break in half, which could have devastating effects on the surrounding environment.
How did it happen? It is believed that harsh weather conditions caused the leak.
Who caused it? The cracked vessel, MV Wakashio, is operated by the Japanese Mitsui OSK Lines.
More facts The spill occurred near two environmentally protected marine ecosystems, as well as the Blue Bay Marine Park reserve. There are also mangrove plantations and well-known beaches nearby.
Threatened birds, captive fruit bats, and thousands of plants were removed from a nearby island, Ile aux Aigrettes by conservation activists.
Using technology to mitigate spills Human error is the leading cause for maritime accidents.
By integrating AI into the complicated world of global transportation, we can reduce and possibly even eliminate the risks associated with long-distance, heavy-duty shipping routes.
- Use predictive analysis to prevent spills
- Expedite response-time
- Mitigate risks for clean-up efforts
Bottom line Using AI in shipping and clean-ups lessens the risk of future spills, and reduces the impact of existing disasters.

The scoop Whales accumulate carbon throughout their lifetime and die with it on the ocean floor. So they save around 33 tons of carbon from the atmosphere each.
Why it matters Today, whales number approximately 1.3 million, and conservation efforts to return them to their 4-5 million pre-whaling population could significantly reduce the greenhouse effect by lowering atmospheric carbon dioxide. However, they are constantly at threat of being hunted.
Big picture Recovering the global whale population to even half its original size is no easy feat, but we must do all in our power to multiply whale species’ populations in all of Earth’s oceans. Regardless of whether a high-tech carbon sequestration tool becomes widely available, harnessing the carbon-capturing power of these beautiful creatures will always positively enhance our atmosphere and marine ecosystems.

Big picture Did you know that 44 nations could disappear under the sea within your lifetime? Pacific Islanders face a desperate need for climate action.
What to know Back in 2017, I had the privilege to attend as a student observer at the United Nations Framework Convention on Climate Change (UNFCCC) International Conference of the Parties (COP 23) in Bonn, Germany.
The most striking presentation involved a group of representatives of the SIDS (small island developing states). The Pacific Climate Warriors spoke about the urgency of their daily and ever-present struggle against climate change.
A 2008 UN report found that the response of island nations to climate change is largely project-based, ad hoc, and heavily dependent on external resources. Australia and New Zealand have contributed financial support to adaptation efforts.
Bottom line For Pacific Islanders, climate action is more than just a school project, it is an existential threat.

What happened On the evening of April 20th 2010, a blowout occurred on the Deepwater Horizon oil rig. High-pressure methane gas had risen into the drilling rig, quickly igniting and exploding.
Visible from 40 miles away, the flames overwhelmed first responders.
Two days later, the platform sank, leaving oil gushing at the seabed...until July, 87 days later. Containment started immediately, stopping the fires and oil burst. Clean up continued and ended...TBA.
Big picture Deepwater is not the first major spill, nor it seems, likely the last, and each disaster results in another human and environmental catastrophe.
- Deepwater killed 11 people, injured dozens of others, left vast swaths of ocean fatally contaminated, thousands of miles of beach polluted, killed over one million birds and continues to destroy pristine habitat and wildlife
- There are 175 offshore rigs in the Gulf of Mexico with the global total growing to 497 by 2017
Why it matters Deepwater displayed the frailties of our petroleum addiction as clear as day. In 2010, the year of the disaster, the planet used about 86 million gallons of Black Gold every day. Now, we use 100 million gallons every day. Black Gold is unsustainable, damaging to the environment, and could be replaced with sustainable alternatives.
We need a global intervention, a massive mobilization focused on powering our planet with the bountiful clean energy nature so gracefully provides. And we must develop an economic model that hastens the long overdue demise of Black Gold.
