Environmental Impact Assessment

Before a big project like a highway, dam, or factory is built, experts study how it might affect the environment. This study is called an environmental impact assessment. It looks at how the project could affect air, water, plants, and animals. The goal is to find ways to reduce harm before building begins.

How It Works

An environmental impact assessment starts by describing the proposed project. Then experts study the area to find out what plants, animals, and natural resources are there. They predict how the project might affect the environment. Finally, they suggest ways to reduce or avoid harm, like building wildlife crossings over highways.

Why It Is Important

Environmental impact assessments help protect nature from unnecessary damage. They give communities a chance to voice their concerns before a project starts. In many countries, these assessments are required by law. They have helped save forests, rivers, and endangered species by changing project plans before any damage is done.

Fun Facts

• The United States was one of the first countries to require environmental impact assessments, starting in 1970.
• More than 100 countries around the world now require environmental impact assessments for major projects.
• Some assessments study not just the environment but also how a project affects local communities and historical sites.
