There is no “one-size-fits-all” solution to these threats. However, even as we recognize that improving the welfare of free-ranging wild animals is difficult, we believe that humans have a responsibility to help whenever we can.
-
-Our staff explores how humans can beneficially coexist with animals through the lens of wild animal welfare. 
-
-We respect wild animals as individuals with their own needs and preferences, rather than seeing them as mere parts of ecosystems. But this approach demands a richer understanding of wild animals’ lives. 
-
-We want to take a proactive approach to managing the welfare benefits, threats, and uncertainties that are inherent to complex natural and urban environments. Yet, to take action safely, we must conduct research to understand the impacts of our actions. The transdisciplinary perspective of wild animal welfare draws upon ethics, ecology, and animal welfare science to gather the knowledge we need, facilitating evidence-based improvements to wild animals’ quality of life.
-
-Without sufficient public interest or research activity, solutions to the problems wild animals face will go undiscovered. 
-
-Wild Animal Initiative currently focuses on helping scientists, grantors, and decision-makers investigate important and understudied questions about wild animal welfare. Our work catalyzes research and applied projects that will open the door to a clearer picture of wild animals’ needs and how to enhance their well-being. Ultimately, we envision a world in which people actively choose to help wild animals — and have the knowledge they need to do so responsibly.`,

 Secrets are strings that shouldn't be checked into Git (eg API keys, passwords). We store these using [Google Secret Manager](https://console.cloud.google.com/security/secret-manager), which provides them as environment variables to functions that require them. Some useful workflows:
 
-- Set a secret: `$ firebase functions:secrets:set STRIPE_APIKEY`
-  - Then, enter the secret in the prompt.
+- Set a secret: `$ firebase functions:secrets:set stripe.test_secret="THE-API-KEY"`
