Long story short: tell Brazil's government to protect the rights of indigenous folks from corporate land-rapers, tell your Congressfolk to fund our IRS, fund home and community care, reject the privatization of public assets, and protect us from PFAS chemicals, and tell your Senators to pass the Equality Act. Use the tools in the upper right-hand corner of this page (or, if you're on a cellphone, the bottom of this page) to find your Congressfolk's phone numbers, or use the email/petition tools in the following paragraphs.
First things first: Sum of Us helps you tell Brazil's Congress to reject a bill that would allow the Brazilian government to force indigenous peoples from their lands in the Amazon rain forest so that big corporations can develop it. It's not just that the Amazon rain forest is the greatest carbon capture machine the world has ever seen, it's that people live there, and people are more important than profits, more important than development, and more important than some politician's "legacy." Besides, the indigenous people of the Amazon have been a thorn in Jair Bolsonaro's side since day one of his ignominous reign, and any enemy of Jair Bolsonaro is a friend of mine. And yours.
Progress America helps you tell your Congressfolk to fully fund our IRS so it can catch more tax cheats. People who avoid their taxes cheat all of us, after all -- they cheat all of us out of roads, bridges, schools, police officers, firefighters, and libraries. Naturally Republicans have balked at more funding for the IRS as a way of helping to pay for the "bipartisan" "infrastructure" "deal" they're continuing to hash out, plus the ProPublica reporting about rich folks' tax evasion has made Republicans more defensive of rich folks than of the rest of us, whom they have cheated. I guess they're objectively pro-crime, then! Why do Democrats not paint them this way every day? Because it would be "uncivil"?
The National Domestic Workers Alliance helps you tell Democratic Senate Majority Leader Schumer to ensure the $400 billion proposal for care infrastructure makes it into the big reconciliation bill Democrats are planning later on this year. Presumably Democrats will pass that without Republican help, so all we need to do now is ensure that Democrats don't eject it from the bill because, oh, gosh, I don't know? Because they like shooting themselves in the foot? Because "bipartisanship"? Because debt and spending and I'M SCARRRREEEEDDDDD!!!!!! OK, maybe I'm being a bit harsh, this time -- our government has never invested this much in home and community care before, prospect of creating a million jobs or not. But if you want to make progress, you have to take big steps. Bigger than Democrats are accustomed to taking, to be sure, but we need to be the spine in their back. At least then they'll have a spine.
Daily Kos helps you tell your Congressfolk not to let the "bipartisan" "infrastructure" "deal" privatize public assets in order to pay for other public assets. President Biden wanted to fund it with higher corporate taxes, but Republicans, being the party of "fiscal responsibility," prefer smoke and mirrors, like "user fees" and selling off some bridges and roads and suchlike in order to pay for others. But we need only look to Chicago's privatized parking meters and Bayonne's privatized water system to see what that bodes for America -- higher prices and worse service. You know, like they're trying to do with our Postal Service. Who voted for that? I don't think even Trump voters voted for that.
Penn PIRG helps you tell your Congressfolk to pass H.R. 3990/S. 2047, the No PFAS in Cosmetics Act. PFAS chemicals, as you may know, are the "forever chemicals" you find in carpeting, cookware, food packaging -- and, eventually, in our drinking water and our bodies, where it might well help give you and/or your loved ones cancer, a weakened immune system, or a learning disability. You also find it in cosmetics, and though you may not wear makeup, someone else does, and they wash it off their face at night, and then guess where it goes? Into your drinking water, and into your body. (Consumer Reports also helps you tell your Congressfolk to pass H.R. 2467, the PFAS Action Act, which would do more about PFAS chemicals generally; the former bill has a better chance of passing, but there's no reason you can't say you support both.)
Finally, the Daily Kos Liberation League, People for the American Way, and Ultraviolet all help you tell your Senators to pass H.R. 5, the Equality Act. The other side has their people calling their Senators going WAAAAAAAAAAH WHATZ ABOUTZ MY RELIGUZ BELIEFZ!!!!!! and WAAAAAAAAAAAH TEH BOYZ WILLZ BEATZ TEH GURLZ ATZ TEH FIELD HOCKEYZ!!!!!!, so we need to be on the horn with our Senators talking about stopping banks and bosses and landlords from discriminating against gay and transgender folks, which is what the Equality Act is actually about. Republican Senators, in particular, pretend the hysterical opinions count more than yours. But we civilized people must make our will unmistakable.
