The average phosphate molecule spends 20000 to 100000 years cycling through the ocean. To speed the replenishment of the soil, farmers include large amounts of phosphate fertilizers which can runoff into streams, rivers, and the sea. What is a possible side effect of this? Excess phosphate fertilizer produces a shortage across the entire region and hinders other agriculture

Excess phosphate fertilizer causes algae growth and oxygen decline, leading to fish kills and deadzones.

Excess phosphate washes up on the beaches, ruining the sand and shoreline.

Excess phosphate fertilizer causes rapid seaweed growth with clogs up the motors of boats and large sea-going vessels.​

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
