keskkonnatähised

Keskkonnatähised, also known as environmental indicators, are measurable variables that provide information about the state of the environment. They are used to monitor and assess the condition of ecosystems, natural resources, and the impacts of human activities on the environment. Environmental indicators can be physical, chemical, or biological in nature and are often used in conjunction with other data to support environmental management and policy decisions.

There are various types of environmental indicators, including:

1. Physical indicators: These measure physical aspects of the environment, such as temperature, precipitation, and water quality.

2. Chemical indicators: These measure the presence and concentration of chemicals in the environment, such as pollutants in air, water, or soil.

3. Biological indicators: These measure the health and functioning of ecosystems, such as biodiversity, species abundance, and ecosystem services.

Environmental indicators are typically selected based on their relevance to specific environmental issues or objectives. They are often standardized and regularly monitored to provide consistent and comparable data over time. Environmental indicators can be used to track trends, identify emerging issues, and evaluate the effectiveness of environmental management strategies.

In summary, keskkonnatähised are essential tools for understanding and managing the environment. They provide valuable information about the state of ecosystems and the impacts of human activities, helping to inform decision-making and promote sustainable development.
