Presentation transcript:

Usage  Fertilizer is used to grow more plants at a faster rate  Plants need nitrogen(N), phosphorus(P) and potassium(K) to grow. Chemical fertilizers contain these elements  Overuse of chemical fertilizers leads to multiple problems due to runoff

Dead Zones

Other Problems  Reproductive problems in fish  Thyroid and reproductive problems in humans and livestock  Increased demand for bio-fuels  Earth’s soil is being depleted of nutrients over 13% faster then they can be replenished.

Solutions  Organic farming Crop rotation Natural Fertilizers Rethink the costs ○ Agricultural chemicals, machinery, fuel costs, buildings Action
