There are numerous things that individuals can do to help protect the environment so that the next generation can enjoy a thriving, luxuriant planet. Some of these things seem small or insignificant when considered as individual acts, but the key is to help everyone commit to becoming more environmentally aware.
One vital step is to become mindful of what you throw away. As the NOAA states on its website: "reduce, reuse, and recycle." Reduce means to reduce the amount of what you throw away. Food waste is hazardous to the environment because it creates methane, which is a greenhouse gas. Only prepare the amount of food you will eat, and save the leftovers for later instead of throwing them away. Reuse means that you don't buy disposable products, but instead those that will last. For instance, you can bring shopping bags to the supermarket rather than get new ones each time and then throw them away. Recycle means to put glass, metal, plastic, paper, and other recyclable materials into special bins so that they can be reconstituted for further use.
You can also conserve water as much as possible. Fresh water is a precious and limited resource, and a lot of energy is used up in getting it to your home. Limit the amount of time you spend in the shower. When you are brushing your teeth, turn off the tap. Run dishwashers only when they are full.
Cars are incredibly wasteful of energy. Whenever possible, use public transportation, ride a bike, or walk. If you have to use a car to get to work or school, carpool with colleagues or fellow students.
Turn off electronic devices when they are not in use. This includes computers, televisions, fans, heaters, air conditioners, and lights. Whenever possible, hang dry laundry instead of using energy-wasteful clothes dryers. Replace normal light bulbs with energy-efficient LED bulbs.
These are all simple things that you can do in normal everyday life to help preserve the environment for people to come. If you want to do even more, you can plant trees that will grow to maturity for future generations, volunteer for environmental causes, donate money to organizations that work to protect the environment, and speak out to others about the great need to be environmentally conscious.
