Jinger is very proactive in thinking of ways that she can reduce her impact on our freshwater resources. With only 3% of the Earth providing necessary freshwater supplies, humans cannot afford to waste or poison the water. Keep litter, pet wastes, leaves, and debris out of street gutters and storm drains to keep sewer systems from being overwhelmed with materials that need to be sorted and cleaned. Disposing of used oil, antifreeze, paints, and other household chemicals properly are essential for lakes and ponds in nearby areas. Water run-off from hosing these materials out of driveways or flushing them down storm drains leads to absorption and spread. Applying lawn and garden chemicals sparingly and according to directions will help to reduce waste and overuse of harmful chemicals that leak into water sources.

Energy consumption and the sources used to feed this every growing need are a constant battle and concern in the United States. Reliance on renewable resources would limit the use of petroleum, natural gas, and coal, which are nonrenewable fossil fuels. These resources take millions of years to replenish, and our supply is slowly running out. Renewable resources like hydroelectric power, solar power, and wind power are all options that are a financial investment to start but cost less over time, have a dramatically less negative impact on the Earth, and do not run out. The idea to increase the reliance on renewable sources and decrease the dependence on nonrenewable sources is a scientifically based idea that is reasonable and may work. Using electricity derived from wind, water, or solar power will be beneficial to decreasing emissions.

Blin and Dev are highlighting a significant problem around the world - the reduction of pollinators. These are one of Earth's vital resources because they help plants reproduce and make the fruits and vegetables we consume daily. Pollinators can be birds, bats, bees, butterflies, and many other creatures. They spread pollen from one plant to another, allowing the plant to become fertilized. Planting flowers that bloom in a variety of colors will attract different pollinators to the different colored color petals. This will increase the likelihood of plants being fertilized and reproduction occurring.

Clean air is essential for all citizens of the United States, and according to the EPA, many of our emissions have decreased in recent years, but there is still room for improvement. Hybrid vehicles and electric vehicles have come down in price, making them more affordable for the everyday driver. This new access to an alternative full vehicle reduces the emissions produced. Many cities are improving their public transit infrastructures allowing residents to use busses, trains, and high-speed rail systems to travel. This reduces the number of individual drivers on the roads, so there are fewer emissions.

Pankaj has included useful tips for his teacher and classmates, but there is one that he should not recommend that they follow, "Run the dishwasher only when empty.". This would be quite a waste of water and would not conserve resources. Pankaj should suggest that the dishwasher be run when full so water and electricity are not wasted. Water is a precious natural resource and should not be lost on just a few dirty dishes

Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods. Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Creating electricity with solar energy instead of coal will reduce the dependence on fossil fuels, find a cleaner way to produce electricity, and reserve more coal.

All of the answer choices are correct and are scientific-based solutions to protect natural resources. Having fishing seasons, size limits, and catch limits helps to protect endangered and threatened species of fish, allow them to reach maturity so they can reproduce, conserve the populations of fish we have, and enable reproduction rates to catch up with consumption rates. These rules put in place help to protect Earth's resources.

Only one of the suggestions would help protect Earth's natural water resources - "Turn off the faucet when brushing your teeth." This idea would help to conserve water while the other ideas are wasteful and would increase the consumption of freshwater. Turning off the faucet while brushing your teeth is a small effort that each person could do to help the Earth.

Protecting Earth's resources does not have to be expensive, and there are practical things that each person can do at home to help conserve the resources we have. Composting kitchen scraps instead of sending them to a landfill, taking shorter showers, buying locally grown fruits or vegetables, or planting a garden are just a few ideas that don't cost a lot of money and help the planet!

Many of the foods we eat require water for growth, manufacturing, or transportation. The meat we purchase at the grocery store was once a living organism that needs water to survive. The fruits and vegetables we grow or buy need water to survive. Manufacturing goods require water to run factories and machinery. Most of the things we use and eat have water needed in some form to grow or create. Looking at how much water you use inadvertently may change buying habits.
