Using complete sentences, identify two ways humans in South and Southeast Asia have modified their water supply. What are the positive and negative effects of these modifications?
Answers
Managing the whole water cycle in an urban setting has become a priority because of increasing urbanization in South and South-East Asia.
Clean water access and treatment of wastewater was a significant global concern. Urban water management and supply comprise 3 fundamental, however inter-related, services.
Firstly, clean drinking water is delivered to households without additional treatment. Providing home water-treatment capability by way of using of filters, flocculants, or solar disinfection to make drinking water safe.
Secondly, wastewater collection from both homes and from industrial and commercial sources which would require adequate treatment and disposal afterward in an environmentally-friendly way.
Third is the efficient disposal of storm water, particularly during the monsoon seasons. Implementing rainwater harvesting systems to accumulate and store rainwater for drinking or re-charging underground aquifers
Disadvantages of the above modifications
Rainwater Harvesting: Rainfall is impossible to forecast and poor runoff can also minimize rainwater production, or not. The rainfall in all areas is not the same. Predicting rainfall is also challenging. Therefore, in areas with minimal rainfall it is not advisable to rely on rainwater alone for all your water requirements
Home Water Treatment: Home water treatments may help remover heavy metals such as mercury and chlorine, however they may not be able to remove pesticides. Solar disinfectants is not suitable for improving the quality of huge volumes of water. It does not greatly help in increasing the water quantity or reducing water shortages.
Answer:
ANSWER
Explanation:
HUMAN MODIFICATION OF THE ENVIRONMENT
For thousands of years, humans have modified the physical environment by clearing land for agriculture or damming streams to store and divert water. As we industrialized, we built factories and power plants. While these modifications directly impact the local environment, they also impact environments farther away due to the interconnectivity of Earth’s systems. For example, when a dam is built, less water flows downstream. This impacts the communities and wildlife located downstream who might depend on that water.
Use these resources to teach your students how humans modify the physical environment and the compounding impacts those changes have.
