EFFECTS ON THE ENVIRONMENT:

Farming and Agriculture can have a positive and negative impact on the environment, all depending on what the farmer does to the land. The impact can refer to the soil, water and the uses of the land. The effects can impact the air we breather, the soil and the wildlife habitat. Soil is an essential ingredient in farming and when it is poor, plants cannot grow to their full potential. Contaminated soil puts the public's health at risk. Contaminated water is unpleasant, dangerous and is the reason for endangered ecosystems.. Fertilizer ingredients sprayed on animal feed including potassium, nitrogen and phosphorus naturally occur** **in our environment, but accumulation of these elements is hazardous. Fertilizers are only the beginning part of factory farms' harmful affects on our environment.**


 * Some positive effects of farming:

* Provides many food sources for us like fruits and meats.

* A farm creates space to be able to grow and harvest these crops.  *  the food products are usually fresh and full of nutrients which benefits our health. **

* The introduction of seeds and grasses that have more nutrients, but they can posion and threat the native plant species because they have exotic weeds.
 * Some negative effects on the environment include:
