Combustion is a kind of chemical reaction where a substance quickly burns with oxygen, creating heat and light. But, this process can be tricky because it has some downsides.

1. Environmental Problems

• When things burn, they often release carbon dioxide (CO₂) and other harmful substances. This adds to air pollution and climate change.
• Finding better options than fossil fuels is a big challenge.

2. Wasted Energy

• Many combustion reactions don’t work perfectly, which means some energy and fuel gets wasted.
• For example, if something doesn’t burn completely, it can produce carbon monoxide (CO), which is a dangerous gas.

3. Safety Risks

• The high temperatures and flammable materials that come with burning present serious safety dangers.
• If we’re not careful, explosions can happen.

Solutions
To tackle these issues, we can look at a few different strategies:

• Creating Cleaner Technology: We should invest in research to make burning systems that let out less pollution.
• Switching to Alternative Energy: Using renewable energy, like solar or wind, can help reduce our reliance on burning.
• Raising Awareness: Teaching people about how combustion works can lead to safer practices and new ideas for creating energy.

In short, even though combustion is important for chemical reactions and making energy, we need to work hard on finding cleaner and safer options.
