Answer:
a.) live in a smart community
Explanation:
A standard incandescent light burns through 50 watts of electricity per hour. Replacing an incandescent bulb with an LED bulb can save 6 tons of household emissions per year. Saving 6 tons of carbon emissions is the same as reducing your gas consumption by 700 gallons. (proving b wrong)
you can help reduce your carbon footprint and other greenhouse gases by using energy-efficient home appliances since they have lower emissions of harmful gases into the environment. (proving c wrong)
Salinity refers to an increase in the dissolved salt content of a body of water. Salinity has great impacts on the type of organisms that live inside the water. In the question given above, the salinity occurs as a result of non natural influence; since most of the organisms living inside the water before probably have specific optimal salinity range, if the salinity exceed the range they can cope with, they will probably migrate away from the water, those that refuse to migrate will probably die out and new species which can cope with the salinity level will emerge.
