Ultraviolet radiation, being of greater frequency than visible light, can affect organisms on a genetic level. They break bonds in the DNA molecule and prolonged exposure can cause adverse effects to essential genes.
UV light is more energetic than visible light, and can pass through the protective layer in the skin to reach DNA molecules, causing a higher incidence of copying errors which can then lead to cancer. This is because the energy packet of UV light is close the bond energy of the Hydrogen molecule in chemicals. - the UV breaks the hydrogen bond thus making the molecule imperfect and may leave a polar charge behind.
UV radiation is a mutagen, meaning it can causes changes to DNA which can result in cancers. It can also cause radiation burn.
the viroids harm the plants that are ifected with them by giving the plants some harmful thing
Certain types of bacteria can be harmful to the environment. Others help with natural processes like decomposing and stuff like that. So, it depends what kind of bacteria you are talking about.
Nuclear weapons testing can have negative impacts on the environment. They can make plants, soil and rain radioactive. This is extremely harmful to humans. Radioactivity can cause mutations in humans and animals.
Plants and animals.
you can help plants by not plucking them,you can help plants by watering them.you can help animals by feeding them,sheltering them, if they are lost giving them to the police.etc!!!!!!!!!!!
Ozone is not an atom, but a molecule containing 3 Oxygen atoms. In the lower atmosphere, it is harmful to plants an animals, but it is beneficial in the upper atmosphere, as it protects Earth from ultraviolet radiation.
High up in the stratosphere, the ozone layer absorbs most of the sun's harmful ultraviolet radiation, UV-B, that would otherwise reach the earth. UV-B is damaging to plants and animals including human beings. Down here on the ground, ultraviolet rays can be blocked by good sunglasses, sunscreen lotion, wide brimmed hats, and adequate clothing.
The UV rays can cause mutations in plants, and can cause sunburn and skin cancer in humans. Fortunately most of the harmful ultraviolet rays are absorbed by the ozone layer high in the stratosphere.

The plants absorbs the solar radiation and energy.
Ultraviolet radiation from the sun passes through the atmosphere and reacts with plants, animals and the soil and water - unless it is absorbed by chemical reactions that it initiates in the upper atmosphere.
harmful effects of polythene on animals
Vacuoles in plants have poisonous substances that can be harmful or deadly to animals.
invacive species
it is harmful for plants and useful for animals
A harmful environment is one where there is some agent or condition in the environment that may cause impaired health or disease to people, plants or animals or that may damage people, plants, animals, property or other elements of the environment.
