"Aluminium is primary among the factors that contribute to the loss of plant production on acid soils. Although it is generally harmless to plant growth in pH-neutral soils, the concentration in acid soils of toxic Al3+ cations increases and disturbs root growth and function." Wikipedia

Red mud residue and caustic soda from the alumina refinery in Yirrkata,
Queensland was found poisonous to fish. (See Aluminum and Our Environment,

It is also very easily leached out into ground water.

Actually the effects are large. Not the aluminium itself, but its production from bauxite is a very high consumer of electricity. So fossil fuels need to be burned, and pollution enters the atmosphere. Many smelters (about 55%) get their electricity from eco-friendly sources such as hydro electricity. It takes about 15 KwHours of electricity to produce 1 kg of aluminium, although once produced, aluminium can be recycled efficiently.
The link below has information, but it is an industry website, so is biased in favour of producers.

Except for the unsightliness of cans beside the road, the effects are not significant. Aluminum is not toxic, nor are its corrosion products.

it does not have any such dangerous effect on the environment
