My biggest tip for fanfic writers is this: if you get a character's mannerisms and speech pattern down, you can make them do pretty much whatever you want and it'll feel in character.
Logic: Characters, just like real people, are mallable. There is typically very little that's so truly, heinously out of character that you absolutely cannot make it work under any circumstance. In addition, most fans are also willing to accept characterization stretches if it makes the fic work. Yeah, we all know the villain and the hero wouldn't cuddle for warmth in canon. But if they did do that, how would they do it?
What counts is often not so much 'would the character do this?' and more 'if the character did do this, how would they do it?' If you get 'how' part right, your readers will probably be willing to buy the rest, because it will still feel like their favourite character. But if it doesn't feel like the character anymore, why are they even reading the fic?
Worry less about whether a character would do something, and more about how they'd sound while doing it.

I love when characters are always drawn in lab coats even outside the lab because it implies that 1) they are either constantly violating lab safety rules or 2) they have a second, casual lab coat purely for external use

what farming items in mmorpgs has taught me: i used to think using ice trays to make ice cubes was free but after thinking about it i have to pay the electric bill to power the freezer so every moment that i’m not freezing new trays of ice cubes is a moment that i’m underutilizing the freezer and increasing the cost of ice cubes. i have to constantly swap out ice trays for new ice cubes on an hourly rotation on a 24 hour basis or else i won’t produce the maximum amount of ice cubes possible and will underutilize the full potential of my electric bill. i need to stop using all other appliances and utilities in my home to make more ice cubes

If you're feeling anxious or depressed about the climate and want to do something to help right now, from your bed, for free...
Start helping with citizen science projects
What's a citizen science project? Basically, it's crowdsourced science. In this case, crowdsourced climate science, that you can help with!
You don't need qualifications or any training besides the slideshow at the start of a project. There are a lot of things that humans can do way better than machines can, even with only minimal training, that are vital to science - especially digitizing records and building searchable databases
Like labeling trees in aerial photos so that scientists have better datasets to use for restoration.
Or counting cells in fossilized plants to track the impacts of climate change.
Or digitizing old atmospheric data to help scientists track the warming effects of El Niño.
Or counting penguins to help scientists better protect them.
Those are all on one of the most prominent citizen science platforms, called Zooniverse, but there are a ton of others, too.
Oh, and btw, you don't have to worry about messing up, because several people see each image. Studies show that if you pool the opinions of however many regular people (different by field), it matches the accuracy rate of a trained scientist in the field.
--
I spent a lot of time doing this when I was really badly injured and housebound, and it was so good for me to be able to HELP and DO SOMETHING, even when I was in too much pain to leave my bed. So if you are chronically ill/disabled/for whatever reason can't participate or volunteer for things in person, I highly highly recommend.
Next time you wish you could do something - anything - to help
Remember that actually, you can. And help with some science.

Planet's Fucked: What Can You Do To Help? (Long Post)
Since nobody is talking about the existential threat to the climate and the environment a second Trump term/Republican government control will cause, which to me supersedes literally every other issue, I wanted to just say my two cents, and some things you can do to help. I am a conservation biologist, whose field was hit substantially by the first Trump presidency. I study wild bees, birds, and plants.
In case anyone forgot what he did last time, he gagged scientists' ability to talk about climate change, he tried zeroing budgets for agencies like the NOAA, he attempted to gut protections in the Endangered Species Act (mainly by redefining 'take' in a way that would allow corporations to destroy habitat of imperiled species with no ramifications), he tried to do the same for the Migratory Bird Treaty Act (the law that offers official protection for native non-game birds), he sought to expand oil and coal extraction from federal protected lands, he shrunk the size of multiple national preserves, HE PULLED US OUT OF THE PARIS CLIMATE AGREEMENT, and more.
We are at a crucial tipping point in being able to slow the pace of climate change, where we decide what emissions scenario we will operate at, with existential consequences for both the environment and people. We are also in the middle of the Sixth Mass Extinction, with the rate of species extinctions far surpassing background rates due completely to human actions. What we do now will determine the fate of the environment for hundreds or thousands of years - from our ability to grow key food crops (goodbye corn belt! I hated you anyway but), to the pressure on coastal communities that will face the brunt of sea level rise and intensifying extreme weather events, to desertification, ocean acidification, wildfires, melting permafrost (yay, outbreaks of deadly frozen viruses!), and a breaking down of ecosystems and ecosystem services due to continued habitat loss and species declines, especially insect declines. The fact that the environment is clearly a low priority issue despite the very real existential threat to so many people, is beyond my ability to understand. I do partly blame the public education system for offering no mandatory environmental science curriculum or any at all in most places. What it means is that it will take the support of everyone who does care to make any amount of difference in this steeply uphill battle.
There are not enough environmental scientists to solve these issues, not if public support is not on our side and the majority of the general public is either uninformed or actively hostile towards climate science (or any conservation science).
So what can you, my fellow Americans, do to help mitigate and minimize the inevitable damage that lay ahead?
I'm not going to tell you to recycle more or take shorter showers. I'll be honest, that stuff is a drop in the bucket. What does matter on the individual level is restoring and protecting habitat, reducing threats to at-risk species, reducing pesticide use, improving agricultural practices, and pushing for policy changes. Restoring CONNECTIVITY to our landscape - corridors of contiguous habitat - will make all the difference for wildlife to be able to survive a changing climate and continued human population expansion.
**Caveat that I work in the northeast with pollinators and birds so I cannot provide specific organizations for some topics, including climate change focused NGOs. Scientists on tumblr who specialize in other fields, please add your own recommended resources. **
We need two things: FUNDING and MANPOWER.
You may surprised to find that an insane amount of conservation work is carried out by volunteers. We don't ever have the funds to pay most of the people who want to help. If you really really care, consider going into a conservation-related field as a career. It's rewarding, passionate work.
At the national level, please support:
The Nature Conservancy
Xerces Society for Invertebrate Conservation
Cornell Lab of Ornithology (including eBird)
National Audubon Society
Federal Duck Stamps (you don't need to be a hunter to buy one!)
These first four work to acquire and restore critical habitat, change environmental policy, and educate the public. There is almost certainly a Nature Conservancy-owned property within driving distance of you. Xerces plays a very large role in pollinator conservation, including sustainable agriculture, native bee monitoring programs, and the Bee City/Bee Campus USA programs. The Lab of O is one of the world's leaders in bird research and conservation. Audubon focuses on bird conservation. You can get annual memberships to these organizations and receive cool swag and/or a subscription to their publications which are well worth it. You can also volunteer your time; we need thousands of volunteers to do everything from conducting wildlife surveys, invasive species removal, providing outreach programming, managing habitat/clearing trails, planting trees, you name it. Federal Duck Stamps are the major revenue for wetland conservation; hunters need to buy them to hunt waterfowl but anyone can get them to collect!
THERE ARE DEFINITELY MORE, but these are a start.
Additionally, any federal or local organizations that seek to provide support and relief to those affected by hurricanes, sea level rise, any form of coastal climate change...
At the regional level:
These are a list of topics that affect major regions of the United States. Since I do not work in most of these areas I don't feel confident recommending specific organizations, but please seek resources relating to these as they are likely major conservation issues near you.
PRAIRIE CONSERVATION & PRAIRIE POTHOLE WETLANDS
DRYING OF THE COLORADO RIVER (good overview video linked)
PROTECTION OF ESTUARIES AND SALTMARSH, ESPECIALLY IN THE DELAWARE BAY AND LONG ISLAND (and mangroves further south, everglades etc; this includes restoring LIVING SHORELINES instead of concrete storm walls; also check out the likely-soon extinction of saltmarsh sparrows)
UNDAMMING MAJOR RIVERS (not just the Colorado; restoring salmon runs, restoring historic floodplains)
NATIVE POLLINATOR DECLINES (NOT honeybees. for fuck's sake. honeybees are non-native domesticated animals. don't you DARE get honeybee hives to 'save the bees')
WILDLIFE ALONG THE SOUTHERN BORDER (support the Mission Butterfly Center!)
INVASIVE PLANT AND ANIMAL SPECIES (this is everywhere but the specifics will differ regionally, dear lord please help Hawaii)
LOSS OF WETLANDS NATIONWIDE (some states have lost over 90% of their wetlands, I'm looking at you California, Ohio, Illinois)
INDUSTRIAL AGRICULTURE, esp in the CORN BELT and CALIFORNIA - this is an issue much bigger than each of us, but we can work incrementally to promote sustainable practices and create habitat in farmland-dominated areas. Support small, local farms, especially those that use soil regenerative practices, no-till agriculture, no pesticides/Integrated Pest Management/no neonicotinoids/at least non-persistent pesticides. We need more farmers enrolling in NRCS programs to put farmland in temporary or permanent wetland easements, or to rent the land for a 30-year solar farm cycle. We've lost over 99% of our prairies to corn and soybeans. Let's not make it 100%.
INDIGENOUS LAND-BACK EFFORTS/INDIGENOUS LAND MANAGEMENT/TEK (adding this because there have been increasing efforts not just for reparations but to also allow indigenous communities to steward and manage lands either fully independently or alongside western science, and it would have great benefits for both people and the land; I know others on here could speak much more on this. Please platform indigenous voices)
HARMFUL ALGAL BLOOMS (get your neighbors to stop dumping fertilizers on their lawn next to lakes, reduce agricultural runoff)
OCEAN PLASTIC (it's not straws, it's mostly commercial fishing line/trawling equipment and microplastics)
A lot of these are interconnected. And of course not a complete list.
At the state and local level:
You probably have the most power to make change at the local level!
Support or volunteer at your local nature centers, local/state land conservancy non-profits (find out who owns&manages the preserves you like to hike at!), state fish & game dept/non-game program, local Audubon chapters (they do a LOT). Participate in a Christmas Bird Count!
Join local garden clubs, which install and maintain town plantings - encourage them to use NATIVE plants. Join a community garden!
Get your college campus or city/town certified in the Bee Campus USA/Bee City USA programs from the Xerces Society
Check out your state's official plant nursery, forest society, natural heritage program, anything that you could become a member of, get plants from, or volunteer at.
Volunteer to be part of your town's conservation commission, which makes decisions about land management and funding
Attend classes or volunteer with your land grant university's cooperative extension (including master gardener programs)
Literally any volunteer effort aimed at improving the local environment, whether that's picking up litter, pulling invasive plants, installing a local garden, planting trees in a city park, ANYTHING. make a positive change in your own sphere. learn the local issues affecting your nearby ecosystems. I guarantee some lake or river nearby is polluted
MAKE HABITAT IN YOUR COMMUNITY. Biggest thing you can do. Use plants native to your area in your yard or garden. Ditch your lawn. Don't use pesticides (including mosquito spraying, tick spraying, Roundup, etc). Don't use fertilizers that will run off into drinking water. Leave the leaves in your yard. Get your school/college to plant native gardens. Plant native trees (most trees planted in yards are not native). Remove invasive plants in your yard.
On this last point, HERE ARE EASY ONLINE RESOURCES TO FIND NATIVE PLANTS and LEARN ABOUT NATIVE GARDENING:
Xerces Society Pollinator Conservation Resource Center
Pollinator Pathway
Audubon Native Plant Finder
Homegrown National Park (and Doug Tallamy's other books)
National Wildlife Federation Native Plant Finder (clunky but somewhat helpful)
Heather Holm (for prairie/midwest/northeast)
MonarchGard w/ Benjamin Vogt (for prairie/midwest)
Native Plant Trust (northeast & mid-atlantic)
Grow Native Massachusetts (northeast)
Habitat Gardening in Central New York (northeast)
There are many more - I'm not familiar with resources for western states. Print books are your biggest friend. Happy to provide a list of those.
Lastly, you can help scientists monitor species using citizen science. Contribute to iNaturalist, eBird, Bumblebee Watch, or any number of more geographically or taxonomically targeted programs (for instance, our state has a butterfly census carried out by citizen volunteers).
In short? Get curious, get educated, get involved. Notice your local nature, find out how it's threatened, and find out who's working to protect it that you can help with. The health of the planet, including our resilience to climate change, is determined by small local efforts to maintain and restore habitat. That is how we survive this. When government funding won't come, when we're beat back at every turn trying to get policy changed, it comes down to each individual person creating a safe refuge for nature.
Thanks for reading this far. Please feel free to add your own credible resources and organizations.
