New insight into where museum specimens come from is always welcome, would love to be able to apply it to egg collections (many of which are unlabelled due to their collectors being old, bored, 19th century toffs who were only in it for aesthetic value and prestige).

Translation: "Every other landlord round here is hiking the rent, so I reckon I can get away with it too."
This is exploitation, plain and simple. We need robust rent controls now.

The Amazon Soy Moratorium has been one of the greatest successes in halting #deforestation since its implementation in 2006.

It is NOT too late. As long as one tree is still standing, one whale is still swimming, and one child is still breathing it is not too late to protect something precious.
