Irrigation machinery has <u>quadrupled </u>the amount of irrigated land in the US.
Irrigation refers to the act of artificially providing water to land to support the development of crops. It is an antiquated agrarian system and may have been honed as ahead of schedule as 5000 B.C. along the banks of such consistently flooding streams as the Nile. Channels were burrowed to broaden the region secured by the surge, and dams were raised to trap water on the land after the floodwaters had died down. The advancement of preoccupation dams and of water-lifting machines allowed the water system of terrains lying over those typically come to by floodwaters. Remainders of these antiquated structures have been found in Egypt, where all farmlands are flooded; Iraq; Lebanon; Syria; China; India; Peru; Mexico; and the United States. Present day water system frameworks are as yet in view of these two key building developments.
There are about 200 billion stars in our galaxy, with 40 billion of them like our sun, Marcy said. One of his co-authors put the number of sun-like stars closer to 50 billion, meaning there would be at least 11 billion planets like ours
Answer
• Driving a more fuel-efficient car to eliminate “gas guzzling”
• Reducing heating needs
• Reducing lighting needs
Explanation
The three best strategies employed worldwide for conserving non-renewable energy resources are Reduce, Reuse and Recycle( 3R’s). Energy users are encouraged to increase reliance on renewable energies such as solar, wind and geothermal to aid in conserving the scarce fossil fuel that remain.
Walking and biking can be used as a strategy to cut down gas guzzling and manage the limited nonrenewable oil resources. One popular way of heating homes is oil heating. However, the conserve the oil, home owners are supposed to put up storm windows and insulate homes including caulking cracks around doors and windows to reduce heating costs. When using natural gas, users can reduce energy wasting by keeping the thermostat at 70 degrees and shutting off heat when not in use.
