Environmental Impact Assessment
Environmental impact assessment is a study of how a human project or action could harm nature before it starts.
Before you bake a cake, you check if you have enough room on the counter. You look at the bowls, pans, and trays already there. You plan where each item will go so nothing falls off. An environmental impact assessment works the same way — it checks what is already in the space before adding something new.
Explaining environmental impact assessment by grade level
Before people dig up land, they should think about what lives there. Birds, bugs, and plants may lose their homes. A study can show what harm might happen first. Then people can plan ways to cause less damage.
Projects that explore environmental impact assessment
An environmental impact assessment studies harm before a project begins. This experiment does something similar by estimating total landfill volume before choosing between diaper types. By calculating waste across a toddler's lifetime, you assess the environmental cost of each option in advance.
Environmental impact assessment means weighing the harm of an action before you commit to it. Here, that idea becomes hands-on. You mine chips from two cookies — one with no concern for the damage you cause, one with careful effort to keep the cookie intact. When you count the broken chunks left behind, you see the environmental price of each mining method directly. That count lets you decide which approach is worth the cost before you ever choose a side.
