    We all have an idea about the common types of environmental problems. 1.But, the fact is, it does affect mankind, other living forms and the environment as a whole.

    What is light pollution? 2.The obvious cause of light pollution is the use of outdoor lighting products improperly. It can be office lighting, car headlights, station lights, streetlights and many more.

    3.Upon studies, it is found that obvious effects are observed in the behaviour of night animals, for bright light at night makes it difficult for these animals to hunt, wander and perform their regular activities. light pollution is directly or indirectly responsible for causing several plant diseases. Its effects are related to disturbance in the physical rhythm, which contributes to risks of developing cancer cells. So, it’s nothing less than a threat to human health.

    You have already seen the negative effects of light pollution on creatures. Apart from this, the actual cost of misused light is about millions of dollars every year. It also leads to the release of greenhouse gases and global warming4.

    While outdoor lighting and using man-made lighting products are part of our modern lifestyle, some simple ways will surely help in reducing light pollution. For example, while installing outdoor lighting, make sure that they are pointed downwards5. Believe it or not, many people living in the urban areas cannot view clear sky and stars at night. Let’s contribute our part in reducing the pollution.

    A. Light pollution is harmful to both animals and plants.

    B. It presents all forms of misused man-mad light.

    C. After all, fuels are used for producing electricity

    D. Also, use only the required lighting equipment for both home and offices.

    E. Citizens should be forbidden to install outdoor lighting

    F. Light pollution affects animals’ normal activities in the daytime.

    G. However, light pollution may be a new term to many of us.

    Lately,my 90-year-old mom has been more and more quiet and sleepy.This is very odd and disturbing.At the same time,my 92-year-old father has been suffering his own health problems.It is terrible to see my father struggle to get her to talk,say something,when she doesn’t have the energy.

    The other day,I recalled how my mother used to visit a woman named Mrs.Demopolis,a Greek immigrant,who made the best baklava（果仁饼）!She gave lessons on baking hem to my mother.Also,my mom used to bake baklava often for a time and that was absolute pleasure.As I spoke of this over the phone,my silent mom cheered up and said how much she’d like o have one again.

    Now,they live in Florida and I like in Wales,UK with my husband and children,so I can’t go and bring her some baklava or even make some in her kitchen.But what I did suggest was that my father or sister should buy some baklava at a Greek Restaurant and I should do she same,and wouldn’t it be fun to eat our baklava at exactly the same time and so,be together sharing the moment and the pleasure?Both parents loved the idea and we decided to do it.It was lovely to hear a little happiness in her voice.

    Tow days later we both had our baklava and shared the experience.It meant a lot to my parents,and to me,to do this.My mother said she wants to do this again,maybe with another food or even baklava again! Why not?And as she only keeps losing weight instead of gaining,it is good for her to find foods that appeal to her appetite.It is becoming harder to find ways to communicate over the phone,but this was this was at least a very good way to do so.And it was nice,as well,to remind us of pleasant memories of our past.
