A Threat to Rhinos
A South African court recently overturned a national ban on the trade of rhinoceros horns – a decision that was celebrated by the country’s commercial rhino breeders but slammed by animal preservation groups. A moratorium on rhino horn trade had been in effect in South Africa since 2009.
Deforestation in the Amazon Rainforest
The Amazon rainforest is the biggest in the world, larger than the next two biggest combined. It covers over 3 million square miles, roughly the size of the lower 48 states. For this reason, it functions as a critical sink for carbon in the atmosphere.
Corporations To The Rescue
Regardless of the new administration’s position on climate change, America’s corporations have assumed a leadership role in the country’s ability to meet and beat previous domestic climate pledges.
2016 Carbon Progress Report
Last year was a big year for progress in the U.S. power sector. Renewable energy provided nearly 17% of the country’s electricity, up from 13.7% in 2015. The first offshore wind farm in the U.S. opened off the coast of Rhode Island. And most significantly, carbon emissions from the power sector continued to decline and reached the lowest levels in nearly 25 years.
Spider Silk
Spider silk – the protein fiber spun by spiders to make webs, nests, cocoons, and wrapping for prey that they stash away – is a remarkable substance. Its mechanical properties combine high tensile strength and high extensibility or ductility. This allows spider silk to absorb a lot of energy before breaking. It is stronger than steel, but not as strong as Kevlar, for example. On the other hand, it is tougher than either.
Cheap Wind And Solar Power
Multiple studies are now reporting that wind and solar power are the cheapest way to make electricity in a growing number of places around the world. A thorough analysis of the levelized cost of energy – which considers every cost component from capital expenditures to operating and maintenance costs over a lifetime – shows that solar and wind power are winning the day.
Canadian Carbon Tax
The Canadian government has chosen a carbon tax as its national policy to reduce greenhouse gas emissions. This aggressive move could have major repercussions around the world.
