In a normal water phase, rivers eventually empty into oceans, and once in the oceans, the Phosphorus gets absorbed by waterplants like algae.
在正常水相下，河流最终流入海洋，而一旦进入海洋，磷就被藻类等水生植物吸收。

This could cause rapid growth of waterplants in the river, which can lead to the water ways getting clogged with organisms, which can change the flow of the water.
这可能会导致河里的水生植物快速生长，从而导致水道被生物体堵塞，从而改变水流。

We can collect rainwater when it rains heavily, and use it to waterplants.
