Kazeer [188]

Answer:

The policy for controlling environmental mercury pollution should address ways to prevent and control this pollution.  Policy:

  • Ban the incineration of waste
  • Require that coal-burning companies remove mercury from the coal
  • Allocate funds towards research and development for renewable energy resources in the hopes of switching away from coal.
  • Require that products containing mercury be labeled as such.
  • Set up programs that will recycle batteries and mercury-filled products.
  • Set up education programs that will help inform people about mercury pollution.

This policy works by addressing the ways to prevent and control mercury pollution.

Three problems that could result from implementing this policy:

  • Backlash from coal-burning companies.
  • It could take a while before we completely shift away from using coal.
  • Some of the programs that can be set up in this policy can be too expensive to set up and maintain.

The stomach is right above the small intestine, and the small intestine is all wrapped around, and isn't that thick. Nutrients from the food are released to the whole body as energy. The small intestine brings the food to the large intestine, which is five feet long and is near your pelvis, or hips. The large intestine connects to the rectum, and then to the anus. In the large intestine, all the water is absorbed as well as salt.
