Trump asked for $1.5 Trillion for the military.

This would add TRILLIONS MORE TO THE NATIONAL DEBT.

TRUMP WANTS $2.2 TRILLION FOR HIS SPENDING.

BUT HE IS WILLING TO CUT EDUCATION, HEALTHCARE, HOUSING AND VETERANS

MAYBE WE SHOULD TAX THE FUCKING RICH

SAY NO TO THIS PEDOPHILES CRAZY SPENDING

this has gone under the radar, but this crisis has also caused a global spike in the cost of plastic, which seems almost certain to increase the cost of food

similar to energy we need to defossilize food systems, reducing dependence on single-use plastics, shifting to more sustainable reuse models
