  Gardeners may cause environmental damage by the way they garden, or they may enhance their local environment.Damage by gardeners can include direct destruction of natural habitats when houses and gardens are created; indirect habitat destruction and damage to provide garden materials such as peat, rock for rock gardens, and by the use of tapwater to irrigate gardens; the death of living beings in the garden itself, such as the killing not only of slugs and snails but also their predators such as hedgehogs and song thrushes by metaldehyde slug killer; the death of living beings outside the garden, such as local species extinction by indiscriminate plant collectors; and climate change caused by greenhouse gases produced by gardening.
