Answer 2

pollution.

When wood or coal is burnt in air, they produce many types of gases that can be harmful for breathing like carbon dioxide, methane, etc.

These gases can accumulate in air over time and can cause choking due to being dense and lethal.

However, anthracite, that is a form of coal, can be a slightly better alternative to both of them as there can be less pollution while burning it.
