Water Ecology and Economics.
What methods of filtration are they using?
The Spanish people use desalination plants, "Life Straws" and chlorine tablets for water purification. Desalination plants are plentiful in Spain and so are chlorine tablets. Life straws are used less commercially.
How does climate change imapact water scarcity?
Climate change can cause countries to have a deficit of water or have an overload of water. If heat increases, water evaporates quicker. This can cause droughts When it floods, there is too much water and the water destroys the town.
Dead zones are areas in the ocean that lack oxygen. These areas are unsuitable for marine life to live in. These are caused by nutrient pollution. Nutrient pollution is caused by farmers putting too much fertiliser into the soil and the nutrients pollute the ocean causing an overload of algae. The algae consumes too much oxtgen making it unsuitable to live in.
