Q1. soil and water conservation is very important because first soil conservation is important so you can keep the needed nutrients in the soil to stay in the soil so it doesn't run off into the water ways. Water conservation is important so that you can reduce pollution to the ocean cause since Oahu is a big watershed all the soap from washing the car, soil in the construction site and in the farm and if there is no berm or vegetative barrier or cover crop not only the soil but for the farm if it was recently fertilized all of it will run to the ocean also the dog poop from Zoey in the wetlands will run to the ocean.haha:D
Q2. people/farmers plant cover crops because cover crop plants help to lower soil erosion by catching the soil from run off water, the water will hit the plants first not the soil, and the roots from the plants help secure the soil in the ground so that the soil won't be picked off in the runoff. They help the ahupua'a by the mauka it help keeps the soils nutrients in the mountains so that the plants nutrients in the soil won't leave and go to the ocean. It helps the Makai by keeping the ocean clean for the coral reefs. Also if a farmer uses fertilizer and if it runs to the ocean it will start a algal bloom which will absorb all the oxygen in the ocean and the ocean animals will not be able to breathe.
