A textile company has started a program to recycle textiles so they are not added to a nearby landfill as part of the waste stream. The company collects old T-shirts, sorts them by color, breaks down the fibers, and respins the fibers into yarn which is used to make new shirts. The recycling process is different from traditional manufacturing because it does not use dyes and it reduces
the amount of water used in the manufacturing process to make new shirts
(a) One drawback of traditional textile manufacturing is that it can release dyes into nearby rivers
( Identify an ecosystem service provided by rivers.
(1) Assuming the dyes are dark in color, describe how photosynthetic algae living in the water would be affected by the release of dyes into rivers.
(18) Textile dyes often contain heavy metals such as lead, chromium, and cadmium Describe how heavy metals in nearby rivers could affect predators at the top of the food chain

i. An ecosystem service provided by river include water for irrigation and drinking.

ii. Photosynthetic algae living in the water would be affected by the release of dyes into the rivers because dyes can block sunlight and prevent photosynthesis. Algae is the base of most river ecosystem so without direct sunlight due to the dye in the water, the entire ecosystem would be in jeopardy.

iii. Heavy metals in nearby rivers could affect predators at the top of the food chain because the metals consumed by primary and secondary consumers would be digested by the predators on top. The toxins from the heavy metal build up the higher in the food chain.

Explanation:

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
