Microplastics Environmental Impact

I need you guys to write me a informative speech. Below shows you guys what is expected from the speech.

‘’This 5 to 6 minute speech should inform the audience about an issue of public concern that will also lead to your persuasive speech. It requires completion of an informative speech preparation sheet (including brief outline and listing of at least 3 references). Visual aids are also required. This speech is to increase the audience’s knowledge or understanding about a particular issue WITHOUT arguing a particular side or trying to persuade the audience how to feel about the issue. You should select a topic that you find both interesting and useful. Something which you are interested in learning more about and sharing what you learn with the class. You will be expected to turn in a complete preparation outline on both BOLT and a hard copy of your speaking outline handed in the day of your speech. However, the speech itself should be delivered extemporaneously utilizing 4x 6 note card’’

Microplastics Environmental Impact

Title: The Rise of Microplastics in Our Environment

General Purpose: To inform
Specific Purpose: To increase the audience’s understanding of what microplastics are, where they come from, and how they impact the environment and human health.

Speech (5–6 minutes)

Introduction
(Approximately 1 minute)

Imagine drinking a glass of water, only to find out you’re also consuming tiny pieces of plastic. Unseen, tasteless, and nearly impossible to avoid—microplastics have become part of our everyday lives.

Microplastics are a growing concern worldwide. They are present in our oceans, the food we eat, the air we breathe, and even in our bloodstreams.

Today, I will inform you about what microplastics are, where they come from, and the environmental and health concerns they pose. While I’m not here to convince you to take action just yet, I hope this knowledge helps you better understand a pressing global issue.

I. What are Microplastics?

  • Microplastics are tiny plastic particles less than 5 millimeters in size—about the size of a sesame seed.

  • They fall into two categories:

    • Primary microplastics are manufactured small (e.g., microbeads in cosmetics).

    • Secondary microplastics form when larger plastic items—bags, bottles—break down over time.

  • They do not biodegrade; instead, they persist and accumulate in our environment.

II. Sources of Microplastics

  • Common everyday sources include:

    • Synthetic clothing fibers released in laundry.

    • Microbeads in personal care products (now banned in some countries).

    • Breakdown of plastic packaging and litter.

  • Rainwater runoff, industrial waste, and even tire wear contribute to the spread of microplastics.

III. Environmental Impact

  • Microplastics have been found in all major water bodies—oceans, rivers, and lakes.

  • Marine animals often ingest them, mistaking them for food.

    • This causes internal injuries, starvation, or even death.

  • Microplastics can also carry other harmful chemicals and pollutants.

  • They threaten biodiversity and contaminate the food chain.

IV. Human Health Concerns

  • Microplastics have been found in drinking water, sea salt, and even fruits and vegetables.

  • Recent studies show microplastics can cross the blood-brain barrier and accumulate in organs.

  • While the full health impact is still being researched, scientists are concerned about long-term exposure.

    • Potential issues include hormone disruption, inflammation, and unknown toxic effects.

Conclusion

(Approximately 1 minute)

To recap, microplastics are small but dangerous. They originate from the products we use daily, accumulate in nature, and may already be in our bodies.

This issue is complex, and it will take global cooperation, research, and awareness to fully address it.

As we move forward, I invite you to consider how we contribute to this issue and what we can do as individuals and as a society. In my next speech, I’ll explore ways to reduce microplastic pollution and promote sustainable solutions.

Thank you.
