Questions pge 251
a)Because it was open to sea lakes entrances in the 1980s. This is flushing lots of sea water making the lake more salty. Thats whats making it increasingly saline.

b)The lakes water temperature is increasing because of global warming so the temperature in the lakes system is rising.

c)This is because Australia is going through a drought and there is little rainfull to fill up lake Victoria so its becoming less water populated.

d)Vegetation has been removed for Animals creating a great environment for algal blooms. Due to ferteliser and temperature rise, also increases the number of algal blooms.

e) When trees get removed from the edge of creeks there are no roots to keep the soil in place so when it rains, the soil goes into the creeks and stops water from entering the lakes.
