Final answer:
Using cloth napkins instead of paper towels and choosing sustainable transportation methods like walking, biking, or using public transportation are effective ways to reduce environmental impact.
Step-by-step explanation:
a. Use cloth napkins instead of paper towels: By using cloth napkins, you can reduce the amount of waste produced. They can be reused and washed multiple times, reducing the need for disposable paper towels.
d. Walk, bicycle, or use public transportation: These modes of transportation produce fewer carbon emissions compared to driving a car. By reducing the use of personal vehicles, air pollution and greenhouse gas emissions can be minimized.
Option a helps in reducing waste, while option d promotes sustainable transportation methods. Both of these actions lead to a reduced environmental impact by minimizing waste production and emissions.
To reduce your environmental impact, options a (Use cloth napkins instead of paper towels) and d (Walk, bicycle, or use public transportation) are effective. Option a promotes reusable materials, lessening waste, and option d reduces fossil fuel consumption and greenhouse gases from personal vehicles. On the other hand, option b (Purchase single-serving foods at the grocery store) and c (Buy disposable razors, pens, and cameras) increase waste and environmental impact due to excessive packaging and the disposability of items, which contradicts sustainable practices.
