This topological map looks at the world's coffee exporters. It is important to note that this is not the same as coffee growers: Europe, for example, grows no coffee but accounts for more than 1/3 of global export value (presumably by importing coffee beans and processing them into a higher-value product for re-export). howmuch.net/articles/world-map-of-coffee-exports

The warming of lakes in the Arctic is thawing methane, the primary component of natural gas, causing shorelines to collapse and water to hiss, bubble, and even burn. Methane is a potent greenhouse gas. Its release from permafrost and frozen lake bottoms may dramatically accelerate warming trends, part of a positive feedback loop in the Arctic and beyond. www.adn.com/arctic/2018/09/24/across-the-arctic-lakes-are-leaking-dangerous-greenhouse-gases/
New York City's Central Park has a small homeless population that, according to Census records, considers the park home, thus giving Central Park a population density of about 1.6 people per sq. km.
