Even ancient genomes have ghosts within them. The Denisovan genome bears the traces of ancient mixture, not only from Neanderthals but with another even more divergent group – some speculate it might have been Homo erectus. Everywhere geneticists look, they see populations more different than any living people, mixing with each other in small fractions. It is no evolutionary tree. Our evolutionary history is like a braided stream.

Human evolution is more a muddy delta than a branching tree
Humans don’t stand at the apex of an evolutionary tree, but in the muddy waters of a braided genetic delta

Eighty of the solutions in this book already exist and are scaling to become competitive alternatives to now dominant, high-emitting technologies. They are economically viable, proven to reduce greenhouse gas emissions or sequester carbon dioxide, and have the potential to spread throughout the world.
Our approach was to collect as much data from a variety of vetted, widely-cited sources as possible, using our models to assess different potential pathways for global adoption. Since no individual organization, model, or researcher can claim to accurately know the future, or how every technology or practice will perform in every corner of the world, we gathered a wide range projections from multiple sources. This approach allowed us to generate reasonable, defensible guesses at how these solutions can grow and what their impacts could be.
Each solution is modeled based on a comparison between a reference case, assuming little change over the next thirty years, and three scenarios reflecting increasingly more accelerated global adoption.
Plausible Scenario: the case in which solutions on the Drawdown list are adopted at a realistically vigorous rate over the time period under investigation, adjusting for estimated economic and population growth.
Drawdown Scenario: the case in which the adoption of solutions is optimized to achieve drawdown by 2050.
Optimum Scenario: the case in which solutions achieve their maximum potential, fully replacing conventional technologies and practices within a limited, competitive market.
The data derived from models was then inputted into sector-level integration models to generate final results for all solutions within an in global system.

Six-hundred tons of oil has contaminated Brazil’s coast, and authorities have no idea where it’s coming from | National Post

Six-hundred tons of oil has contaminated Brazil's coast, and authorities have no idea where it's coming from
The Brazilian government's apparent inability to answer even basic questions about the spill has drawn more scrutiny to the policies of Jair Bolsonaro
I would say thay the article blaming Venezuela is political, considering the local political landscape, where Bolsonaro pretty much swore to tear up the environment going in. The one which says that they don't know where it is coming from is likely more accurate although he is probably being deceptive. Bolsonaro has been considered responsible for Amazon fires, after he put big business in charge of ecological policies, amongst other disturbing things. https://www.theguardian.com/world/2018/nov/01/bolsonaro-environment-agriculture-ministries-amazon

Fears for Amazon as Bolsonaro plans to merge environment and agriculture ministries
Conservationists fear move will put short-term business interests ahead of the world’s biggest terrestrial carbon sink, indigenous communities and rich eco-systems

The Utah State University with funding from NASA, have been developing new crops for space exploration.
The wheat varieties developed, USU-Apogee and USU-Perigee, are over 50% shorter than normal varieties and are specifically developed to grown with 24 hour sunlight, no soil and with limited space as you would find in a space station or a base on Mars.
Not only they trive in these conditions, they also present a faster lifecycle, with the seeds heads emerging just 23 days after germination.
