To cure the tobacco that a smoker consumes in two weeks it takes the wood from one tree.

To make sure of big crops tobacco growers use large amounts of pesticides and fertilizers (more then they would be allowed to use on food crops). These chemicals can get into drinking water, animals and other crops. Some of the chemicals in these pesticides cause cancer.

Tobacco takes up nutrients from the soil faster than any other crop. This makes the land less fit for growing food.

British smokers throw away about 20 million cigarette packets and about 300 million butts (cigarette ends) every day. Many of these end up adding litter to the streets.

Tobacco contains additives which help to keep the cigarette alight, which increases the risk of fire from disgarded cigarettes.
