Both air pollution and light pollution negatively affects insect pollinators.
Air pollution from vehicles, industry and other sources affects the ability of bees to locate food by interacting with the scents released by the plants and this makes the bees slower at finding their food and therefore less effective at pollination.
Light pollution interferes with those insects that pollinate at night such as moths. Research has shown that the amount of visits to flowers by pollinators at night was 62% lower in areas with street lights compared to unlit areas. This significant loss of pollination results in less seeds and fruits being produced by the plants affected and therefore a reduction in their ability to produce their next generation. Moths especially are also directly attracted to these lights and this exposes them to predators such as bats.
