Biomagnification

Don’t plants filter for themselves? If a plant is dead - don’t eat it. If a plant is still thriving and edible wouldnt it be safe to eat? Because as it’s still alive, it must not be poisoned.

Washoff of fields containing small amounts of pesticides gets into groundwater. This water supports life and you know how the food chain works. Where the magnification comes in is when animals get larger and work up the food chain. Guess who's at the top? Aquatic plantlife grows and contains small amounts of pesticides. The tadpole swims and grows in the water eating the aquatic plantlife only to be eaten by a fish. This wouldn't be so bad, but the fish is larger than the tadpole and therefore must eat more tadpoles. A little bigger fish eats several smaller fish and every step in the chain intensifies the effect of the originally small amount of pesticides. The lower that you eat on the food chain the less impact you will feel from biomagnification. Eat low on the food chain.
