Explanation:

Natural resources may be living or non-living. Their value may be tangible, such as the price of an ounce of gold, or intangible, like the psychological value of being able to visit pristine natural areas. Some natural resources must be used and used wisely, but some must be preserved to maintain their value.
Recycling can help conserve natural resources. Such as 

• Buy less stuff (use items as long as you can, and ask yourself if you really need something new).
• Reduce excess packaging (drink tap water instead of water from plastic bottles).
• Recycle materials such as metal cans, old cell phones, and plastic bottles.
• Purchase products made from recycled materials.
• Reduce pollution so that resources are maintained.
• Prevent soil erosion.
• Plant new trees to replace those that are cut down.
• Drive cars less, take public transportation, bicycle, or walk.
• Conserve energy at home (turn out lights when they are not needed).

Hence option 1st is correct.
