Environmental factors like pollution, changing temperatures, and UV rays can really hurt our DNA. This can cause problems in how our DNA works and can lead to mutations, which are changes that can mess things up. Here’s how these changes can affect us:

• They can harm the double helix structure of DNA.
• They can create mistakes when DNA is copied.
• They can lead to diseases, like cancer.

When people are around more harmful chemicals, it can change their DNA in ways that can't be fixed. This is a big worry, especially with the environment changing so quickly.

But there are ways we can tackle these problems:

1. Regulation: We can make and follow stricter laws to cut down on pollution.
2. Education: Teaching people about how to protect nature and reduce exposure to dangerous substances.
3. Research: Funding studies to understand these issues better and find ways to fix them.

Addressing these challenges is super important to keep our DNA safe and healthy.
