The impact we are now having was first seen with the extinction of the dodo in 1681. The increase in human population has been a key factor as it reduces the habitat for animals and plants. However, this reduction in habitats could be slowed down if we used existing resources better. Air and water pollution are also significant, whilst in the oceans, overfishing and plastic pollution have had a big impact. Global warming will make these factors much worse.

From December 2013 to February 2014 the area was affected by severe flooding causing many farms to be cut off. Homes were flooded and many residents were evacuated as the flood water also mixed with sewage. It had been the wettest January since records began. After the flood water went down, a large‑scale dredging project was undertaken to remove the silt which had been washed up the river from the Bristol Channel. A tidal barrier has been proposed to be built north of Bridgwater on the River Parrett. This will have gates that will close to prevent high tides flowing upstream from the Bristol Channel.

About 30% of California’s water supply comes from groundwater and the rest from surface water. Some groundwater is poor quality, and the cost of pumping is high. Landowners have the right to pump as much water as they want to. The authorities in some parts of California are thinking about desalination as a way to provide water. It is not affected by periods of drought, but it is expensive. Water re‑use is becoming more common and recycled water is used for irrigation, toilets, and industry. Fig. 6.3 Using Fig. 6.3, suggest which one of the following statements is true. Tick (3) one box. tick (3) Cost will be a problem if desalinated water is used for agriculture. Groundwater is the main source used in California. Recycled water is of high quality. Surface water is not important to California.
