Answer 1

Severe water pollution threatens historic Venice. Industrial wastem wewage and saltwater are combining to eat away thefoundations of buildings and damage the buildings themselves. Erosion has allowed increased amounts of seawater into the lagoon. Because of this, floods also endanger the city and fuined many of its buildings and the artwork that they housed. Agricultural creates conditions that promote algae growth, sometiomes called "killer algae" These algae frow rapidly and after they die, decay. The decauing process uses up oxygen in the water, so that fish also die. Dead fish attract insects and create a stench, especially in warm weather.
