How do oil spills affect plants and animals? In general, oil spills can affect animals and plants in two ways: from the oil itself and from the response or cleanup operations. Oil can also smother some small species of fish or invertebrates and coat feathers and fur, reducing birds’ and mammals’ ability to maintain their body temperatures.
How do oil spills affect plants? Oil hampers the growth of plants to a great extent. It cuts off the air supply and sunlight, thus making it impossible for plants to carry out photosynthesis and make food. In the absence of photosynthesis, plants fail to germinate and the growth stops. Plants are not able to transpire and most of them die.
