The "Care It!" Run: 40 Years, 40 Miles, 40 Effective Donations!

To celebrate my 40th, it would be an absolute delight if you considered making a donation to an effective charity!  I will match all donations!

As a silly thank you, I'll be running 40 miles over a few days in a carrot costume! Check out the absurdity: https://www.instagram.com/carrotcatmeow/

If you have a favorite charity, please donate to that one!  If you do not, here are my thoughts:
  •  Some charities are 100x or even 1000x more effective than others. 
  • I am a big fan of highly-researched, effective charities focused on global poverty, climate, and animal welfare

How Giving Multiplier Works! 
  • Feel free to skip all this and Venmo (@eric-spamer) or Paypal (espamer@gmail.com) me and I will donate for you! 
  • Scroll down and follow steps 1-4.  
  • If you don't have a favorite charity, skip step 1 and choose one of my favorites (e.g. GiveDirectly for global poverty, Clean Air Task Force for climate) in step 2!
  • You can split your donation:
    • Choose your favorite charity: Donate a portion to a cause you already love.
    • Get a bonus match: Donate the other portion to one of my favorite charities and you'll receive a bonus match on that portion, increasing your total impact!
My goal is to have 40 people donate $40! 

Please reach out anytime if you want to learn more about these charities and the work I do with some of them!  

You are AWESOME!!!!!!!!!!!
