5 Urgent Thesis Topics on Microplastics in Bottled Drinks You Need to Explore

Source: GMA News Online

Let me convince you to make this a thesis.

You’ve been told that glass is the safer, cleaner, more sustainable choice. You sip your soda from a glass bottle and feel proud. But what if the thing you trusted most is quietly putting plastic into your body? A new study in France just blew that belief apart. They found more microplastics in drinks sold in glass than in plastic. Not less. More. Up to fifty times more. And the worst part? It’s not even coming from the bottle. It’s coming from the cap.

What’s really wrong is we think we're safe. We think choosing eco-friendly materials means choosing health. But there’s a gap in this logic. No one is asking what really happens at the micro level. How does packaging, even the "green" kind, affect what we put in our bodies? There’s no solid proof yet of what these microplastics do to us. But if they’re in our drinks, our food, our lungs, our blood, isn’t that enough to start asking better questions?

Get Your Thesis Title — or Keep Getting Rejected

Bestie, let’s stop pretending you’ve “got it covered.”

You’re here because:

• Your title keeps getting rejected

• You don’t know the difference between a “topic” and a “research gap”

• You’re guessing your way through something that decides your graduation

And let’s be real — you’ve already:
❌ Tried making titles from scratch
❌ Watched “How to Write a Thesis Title” TikToks
❌ Copy-pasted topics from other people's thesis (ooops?)

Still stuck? Exactly.

You don’t need more ideas.

You need a system.

That’s what the Thesis Toolkit gives you:

✅ YTB Thesis Title Booster – because you need legit, research-based topics based on current trends — not random ones na “maganda pakinggan.”

✅ Thesis Title Builder – because you keep forgetting na kailangan may survey source or research instrument ka rin, hindi lang title.

✅ Research Gap Finder – because most of your drafts get rejected for one reason: Walang gap.

YOU NEED THIS IF...

• You're tired of starting over

• You're afraid to open your adviser’s feedback

• You want a title, gap, and source na adviser-friendly and academically sound

This isn’t optional.
It’s either you use this toolkit...
or you keep wasting weeks writing titles na walang mapupuntahan.
