Notes de l'éditeur
- The problem with plastic is that it doesn’t decompose in the way that organic material does. Instead, when it’s dumped into the ocean or other bodies of water, it tends to break down over time into smaller and smaller pieces. These tiny bits of plastic can easily be mistaken for food by birds, small fish or filter feeders, such as clams and sea cucumbers.
- The Beach Environmental Awareness Campaign Hawaii (B.E.A.C.H.) has done their research and sadly discovered that “plastic bottle caps are one of the top 10 items found during marine debris beach clean-ups and are the second most littered item after cigarette butts.” The reason is because these tiny pieces of plastic are especially difficult to recycle. The plastic material used to make these bottle caps is extremely durable, as it is made of oil and natural-gas
- According to a study released this week in the journal PeerJ, devastated the reefs surrounding Hawaii’s number one tourist destination: Hanauma Bay Nature Preserve. Researchers found that 47 percent of the flattest, broadest areas of the snorkeling paradise’s reef had bleached. Just under 10 percent of Hanauma Bay’s corals died.
- Corals are animals often mistaken for minerals because of their skeletal, rock-like structure and slow-growing, immobile nature. And somewhat confusingly, these creatures play host to vegetables. Symbiotic algae dwell inside coral, giving them their colorful cast and providing much needed oxygen and waste removal.
- "Hawaii's renewable energy use has doubled in the past five years, with the islands currently generating about 22 percent of their electricity from wind, solar, geothermal and other renewable energy resources." The bill makes Hawaii the first U.S. state to adopt such a standard.
- Transitioning to 100% renewable energy by 2045 will not be an easy task: there are several challenges that result from the intermittent nature of the most widespread forms of renewable energy, solar and wind. Wind turbines, for instance, must be in a favorable location to produce electricity at a cost-competitive price. Not only must there be wind blowing at an adequate speed to continually generate electricity, there is also usually a need for additional infrastructure to transmit electricity from the generation source to the end-use consumer.
