Answer each question - APA format not needed 100+ word. 1 - How have environmental policies implemented by local leaders affected your daily life? Provide an example . 2 - What do we need to do to further improve the quality of air and water beyond what we already achieved? Please share your thoughts here.

3 - In environmental science, cost calculations are sometimes based on risk considerations. For example, in drinking water applications, the tolerated risk is 1E6 (one in one million); the maximum contaminant levels (MCLs) are generally set based on this risk level. As an example, the MCL for trichloroethylene (TCE) is 5 micrograms per liter. So, if one million people drink water for a lifetime at this concentration of TCE, one person is expected to develop cancer because of this exposure. As a society, this is a risk that is acceptable to us. We neither require nor justify additional expenses for drinking water treatment to levels below the MCL. Question: This is one example of how cost is affected by the level of risk we tolerate. What other factors affect decisions that involve cost in environmental science?

4 - What is meant by risk assessment? Who conducts risk assessments and for what purpose? What are the different steps in risk assessment?

5 - How do trees grow? Where does the mass of trees come from? What are the "stuff" that make up trees and where do they come from? Soil? Air? Water? Sun? Watch the Veritassium video linked below and answer these questions!

6 - How does storing large quantities of water on the surface (as in lakes and reservoirs) cause earthquakes?

Environmental policies implemented by local leaders significantly influence daily life in various ways. For instance, mandates to reduce vehicle emissions have led to the proliferation of cleaner transportation options like electric buses and improved public transit. These policies reduce local air pollution, resulting in health benefits such as fewer respiratory issues and allergies among residents. Additionally, some regions enforce strict waste disposal laws which curb littering and promote recycling, contributing to cleaner neighborhoods and waterways. These initiatives enhance quality of life directly by reducing pollution exposure and indirectly by fostering healthier communities. Such policies showcase how informed leadership can positively shape environmental health and public well-being at the local level.

Despite progress, further improvements in air and water quality are essential. To achieve this, stricter regulations on industrial emissions and vehicle exhaust should be enforced. Promoting renewable energy sources like solar and wind can decrease reliance on fossil fuels, thus lowering pollutants. Investing in advanced water treatment technologies and safeguarding watershed areas will help maintain clean water sources. Public awareness campaigns and education about responsible consumption can also motivate behavioral changes. Collaboration among government agencies, businesses, and communities is vital for implementing sustainable practices. Continuous monitoring and adaptive policies will ensure long-term environmental quality, ultimately safeguarding human health and ecosystems.

In environmental science, cost considerations are often influenced by risk levels tolerated by society. Apart from risk thresholds, factors such as economic feasibility, technological availability, and public acceptance play significant roles. For example, implementing more stringent water standards might be technically possible but economically prohibitive, leading to a balanced decision based on the societal risk acceptable level. Political considerations, environmental justice, and resource availability also impact decision-making. The interplay between scientific data, economic constraints, and societal values shapes policies determining acceptable costs versus benefits. Therefore, risk tolerance isn't the sole factor but one of many that influence environmental cost decisions.

Risk assessment is a systematic process to evaluate potential hazards and their adverse effects on health or the environment. Typically conducted by scientists, public health officials, or environmental agencies, it aims to inform policy and ensure safety standards. The process involves several steps: hazard identification (recognizing potential dangers), dose-response assessment (estimating health effects of exposure levels), exposure assessment (measuring how much people or ecosystems are exposed), and risk characterization (summarizing the overall risk). This comprehensive approach guides regulatory decisions, helps develop safety protocols, and prioritizes resource allocation to mitigate harmful impacts effectively.

Trees grow through a complex biological process starting with seed germination. Once sprouted, they develop roots that absorb water and nutrients from the soil. Photosynthesis, powered by sunlight, allows leaves to convert carbon dioxide and water into sugars and oxygen, enabling growth. The mass of trees primarily comes from carbon molecules fixed from atmospheric CO2, captured by leaves during photosynthesis. Water absorbed from the soil provides hydrogen for the formation of organic compounds. Elements like oxygen, carbon, and hydrogen comprise the main components, with nutrients from soil (nitrogen, phosphorus) supporting development. The sun provides the energy necessary for metabolic processes critical to growth.

The storage of large water bodies like lakes and reservoirs can induce earthquakes through a process called reservoir-induced seismicity. When substantial volumes of water are impounded, the added weight exerts pressure on the Earth's crust, potentially activating existing faults. This additional pressure can alter stress distributions in the subsurface, triggering fault slippage that results in seismic events. Large reservoirs are often situated near tectonic fault lines, increasing the risk of earthquake occurrence. This phenomenon demonstrates how human activities involving significant water storage can influence geological stability, underscoring the importance of seismic risk assessments in dam and reservoir projects.
