- Stop. Breathe. Take a step back. This can all be incredibly overwhelming. Pick the fight that matters most to you and take a few days deciding what success looks like, what strategies will work, and what tactics are available to you. And then hoist your flag and get to work.
- And when you meet someone fighting a different fight, remember to support them. There are already enough fronts to advance without taking friendly fire from our flanks.

Conservation, Popular Culture, Science
If interested citizens want to get involved in conservation and management policy, it’s absolutely vital to use proper terminology. The policy world can be full of confusing jargon, but there are few ways to discredit yourself in the eyes of decision makers as quickly as using a critical term incorrectly. In fact, it isn’t uncommon for a decision maker’s response to a petition or public comment to consist entirely of correcting inaccurate terminology, if a response is issued at all. There are well over 100 acronyms and terms that I’ve seen regularly used, but in the interest of brevity, I’ve selected what I believe to be the 15 most important terms that I’ve seen people repeatedly use incorrectly.
For each term, I’ve provided a definition from a scientific paper or technical report whenever possible. I have also provided some additional explanation in my own words, and some assistance from familiar memes. Whenever possible, I’ve linked to blog posts, articles, or websites that provide even more information. Most of these terms are broadly applicable to fisheries management policy, but some are specific to shark fisheries. It is not my intention with this post to strongly advocate for or against any specific policy (I do plenty of that with other posts), but to make sure everyone is speaking the same language.

Conservation, Science
We are in the midst of a global extinction crisis. Biodiversity is in decline as species after species disappear. Some estimates predict that up to 50% of species will be committed to extinction by 2050. Other estimates claim the current rate of extinction may be 10,000 times the background rate. Many ecologists and conservationists have declared the current species decline the sixth great mass extinction.
A recent paper published in the journal Nature argues that our current estimates of species loss are based on a flawed model and tend to overestimate the magnitude of species decline. The paper has received plenty of attention, and has been heavily criticized by ecologists and conservation biologists. The paper is wrong, but it is wrong for the right reasons, and the criticisms it has garnered point to a gaping hole in our understanding of population dynamics.
