Draft legislation is circulating in Congress right now that weakens the Toxic Substances Control Act. It's what the chemical lobby has spent millions of dollars trying to achieve - and if they get what they want, more people will be exposed to more harmful chemicals and more will get sick.

Dear Republicans,
Cutting science budgets has not historically been a Republican thing. For example, Lincoln created the National Academy of Sciences. Eisenhower's term increased the science budget 366%. Gerald Ford, +15%; George H. W. Bush, +30%; George W. Bush, +54%.
Just sayin’.

Cutting the budget of NASA by 50% will not only have 0 impact on the federal budget, it will also put America in the back seat, while other countries are taking the wheel. The same applies to EPA and NOAA; all three agencies founded by Republican Presidents.

I agree. I believe RFK Jr and the MAHA movement genuinely want to improve public health, but it’s not going to work if on the one hand we are banning food dyes, while on the other we are allowing manufacturers to release toxic chemicals in the environment. At best, this will be a fruitless endeavor.
Thanks for this. 4 sure there are many many toxic chemicals in food, and water and air. I agree about wanting to control our environment. But I also know that unless the government does its job - we will still be exposed to toxic chemicals no matter what.
right now that's not looking so good
