Rccognizc the impact of engineering solutions in an environmental context Explain (60 to 75 words) an engineering solution for reducing greenhouse gas emissions. Discuss (100 to 125 words) the impact of the above engineering solution in an environmental context. Do not discuss the global/social impact of the greenhouse gas emissions. Explain (60 to 75 words) an engineering solution for overcoming lack of clean water in some part of the world. Discuss (100 to 125 words) the impact of the above engineering solution in an environmental context. Do not discuss the global/social impact of the lack of clean water in some part of the world.Explanation / Answer
1. Move Closer to Work—Transportation is the second leading source of greenhouse gas emissions. (burning a single gallon of gasoline produces 20 pounds of CO2). But it doesn't have to be that way.
One way to dramatically curtail transportation fuel needs is to move closer to work, use mass transit, or switch to walking, cycling or some other mode of transport that does not require anything other than human energy. There is also the option of working from home and telecommuting several days a week. It can also make comfortable transport for the rest of the people who are intended to use vehicals which may reduce over traffic on the roads.
2. Cutting down on long-distance travel would also help, most notably airplane flights, which are one of the fastest growing sources of greenhouse gas emissions and a source that arguably releases such emissions in the worst possible spot (higher in the atmosphere). Flights are also one of the few sources of globe-warming pollution for which there isn't already a viable alternative: jets rely on kerosene, because it packs the most energy per pound, allowing them to travel far and fast, yet it takes roughly 10 gallons of oil to make one gallon of JetA fuel. Restricting flying to only critical, long-distance trips—in many parts of the world, trains can replace planes for short- to medium-distance trips—would help curb airplane emissions.
3. Bicycle Water Purifier:
Cycloclean Nippon Basic
"Japanese company Nippon Basic created a durable bicycle equipped
with a water purifier. The bicycle allows users to filter water through pedaling,
enabling access to clean water for those in remote villages and disaster zones.
Equipped with non-puncture tires, a pump and hoses, riders can commute to water
sources, lower the hose into the source (the hose can siphon water as deep as five meters),
raise the bicycle up on its stand thus lifting the rear wheel off the ground, and start pedaling.
As the user rides, water is pumped into the system and passes through a series of micro-filtration
membranes before it’s stored in a container."

Reducing Your Carbon Footprint
But overall, and especially during day-to-day use, bikes are a very green way of getting around. Cyclists don’t burn non-renewable fossil fuels, and they don’t produce air pollution or other harmful emissions.
The U.S. Census estimates that about half of all Americans live within five miles of their workplace. Those who decided to bike those 5 miles every day rather than driving an average car could reduce total household emissions by six percent.
Motor vehicles produce more than 30 percent of U.S. carbon dioxide emissions, more than 80 percent of carbon monoxide, and about half of the nation’s nitrogen oxide emissions each year. Engine “warm-up” means short trips are by far the worst polluters—and those are the journeys most easily made by bike.
Bikers tend to be in good physical shape and are less likely to be obese than motorists. This means they typically use less energy on everything from transportation to food production.
