THREATS TO ECOSYSTEM - Coggle Diagram

- - - - Use environmentally household products.
      - Avoid over dosage of pesticides and fertelisers
      - Don’t throw the non degradable substances to rivers, lake or ocean
      - Pre-treatment of industrial waste water before leaving the water bodies
- - - - Radioactive materials used in this production have high health risks and release a small amount of radioactive pollution.
    - - Mining these involves crushing and processing of the radioactive ores and this generates radioactive waste which emits alpha particles
    - - A number of radioactive isotopes are used in medicine, either for treatment or diagnostics. These can be left to decay over a short period after which they are able to be disposed of as normal waste
    - - Nuclear power plants under current standards produce little radioactive pollution due to safety precautions that must be adhered to. Accidents at these power plants can cause dangerously high radioactive pollution, such as in the case of Chernobyl, and recently in fukushima of japan.
  - - - The impact of radioactive pollution on human beings can vary from mild to fatal; the magnitude of the adverse effects largely depends on the level and duration of exposure to radioactivity. Low levels of localized exposure may only have a superficial effect and cause mild skin irritation
      - Long-term exposure or exposure to high amounts of radiation can have far more serious health effects. Radioactive rays can cause irreparable damage to DNA molecules and can lead to a life-threatening condition.
      - The rapidly growing/dividing cells, like those of the skin, bone marrow, are more sensitive towards radioactive emissions.
      - On the other hand, cells that do not undergo rapid cell division, such as bone cells and nervous cells, aren't damaged so easily.
      - Rays from radioactive element can cause -burns -cancers (skin cancer, lung cancer, thyroid cancer ) -death -hair loss -heart failure -can damage brain cells
