Dear madam, Good question

Only the public awareness can reduce the plastic pollution. First of all, control the source means plastic producing industries. Some rules & regulation to be implemented on that industries. But reality is Plastic is found in virtually everything these days. Your food and hygiene products are packaged in it. Your car, phone and computer are made from it. And you might even chew on it daily in the form of gum. While most plastics are touted as recyclable, the reality is that they're “down cycled.” A plastic milk carton can never be recycled into another carton — it can be made into a lower-quality item like plastic lumber, which can’t be recycled could ​comprise ​education, ​policies, fines ​for littering, ​TV advertisements.

Plastics pollution has a direct and deadly effect on wildlife. Curious marine mammals get entangled and drown in plastic garbage, seabirds feed the bright, colourful pieces to their young instead of food, and sea turtles eat plastic bags mistaking them for jellyfish.
Thousands of seabirds and sea turtles, seals and other marine mammals are killed each year after ingesting plastic or becoming entangled in it; many more suffer after ingesting plastic particles that contain toxic substances, which can cause death, injury or reproductive failure.

“We’re happy to see the EPA taking plastics pollution seriously,” an oceans attorney at the Center. “Every year bits of discarded plastic kill thousands of seabirds, sea turtles, seals and other marine mammals. Some choke on plastic, and others are poisoned by it. Still more find themselves swimming through vast patches of toxic litter. It’s an international tragedy that needs to be addressed.

the Center petitioned the EPA to use its authority under the Clean Water Act to develop water-quality standards for plastic pollution and publish information to guide states in monitoring and preventing harm to waters from plastic pollution. Although the EPA declined to develop plastic-specific water-quality criteria, the agency agreed to expand other efforts to protect people and wildlife from litter in oceans and other aquatic environments.
