Environmental problems cannot be controlled only by personal efforts. Rules and laws are needed for industries, transport, construction, mining, waste management and the use of natural resources.
Need for environmental laws
- To control air, water and soil pollution.
- To protect forests, wildlife and biodiversity.
- To regulate industries and hazardous substances.
- To protect public health and safety.
- To fix responsibility for environmental damage.
- To support sustainable development.
