5.  Droughts are periods of dry weather, especially a long one that is injurious to crops.  Mega droughts are extreme droughts that last for a decade or longer  Most western USA has been in a drought for more than 15 years.  California is number 1 state in running out of water.  The droughts are likely to inflict $2.2 billion in losses on the agricultural industry according to a July study from the university of California.  Temperatures get warmer over time, the prevalence and duration of drought has increased in the American west.

7.  Widespread of cutting down of trees for fuel reduce the soils ability to hold water drying out the ground, triggering desertification(the process by which an area becomes a desert) and leading to drought.  Constructing a dam on a large river may help provide electricity and water near the reservoir. However it may also cause drought downstream by severely reducing the flow of water.

8.  Results of bad droughts can be fierce wild fires, water shortages and potentially staging agricultural losses.  Increased temperatures will lead to more precipitation falling as rain rather than snow.  Losses or destruction of fish and wildlife.

9.  Better monitor and measure water supply and uses nationwide.  Reduce indoor water use through more efficient appliances, technologies, and behaviors.  Make more strategic use of water.  Reduce outdoor water efficiency through drought-tolerant landscape design and improved irrigation technologies.  Increase recycling and reuse of water, including capturing and reusing storm water, greywater and wastewater.

11.  Pollution is the presence in or introduction into the environment of a substance or thing that has harmful of poisonous effects.  The way we get pollution is from cars caused by fossil fuels releasing carbon dioxide which is the largest source of gas emission.  Car pollution has a huge effect no climate change. Car pollution is one of the biggest type of pollution.  Cars and trucks produce air pollution throughout their life, including pollution emitted during vehicle operation, refueling, manufacturing, and disposal.

12.  Pollution can cause diseases such as cancer, lupus, immune diseases, allergies, and asthma.  Air pollution can destroy the Ozone Layer which protects us from the ultra violet rays.  If there is to much Co2 in the atmosphere it can cause smog which can prevent sun light to hit plants and die.

13.  Try to use your car less.  Don’t purchase more cars than you need.  Manufacturing, packaging, and shipping processes all create waste that pollutes the air.  Buy local goods
