Environmental science is all about finding ways to live more sustainably, which means using resources today in a way that maintains their supplies for the future. Environmental sustainability doesn’t mean living without luxuries but rather being aware of your resource consumption and reducing unnecessary waste.
Reduce household energy use
Energy conservation is itself a source of energy. Here are several simple ways to reduce your household energy use:
Turn off appliances and lights that you’re not using.
Install energy-efficient appliances.
Use a programmable thermostat that lowers or raises the temperature when you’re not home.
Set your thermostat lower than usual in the winter and bundle up.
Open windows to allow a breeze instead of turning on the air conditioning.
Hang clothes to dry instead of using the dryer.
Replace incandescent light bulbs with compact fluorescent bulbs (CFLs).
- Eat locally
A powerful way to live more sustainably is to eat locally. The convenience of supermarkets has changed how people think about food. You can stroll through aisles stocked with fruits, vegetables, and other products from all over the world any time of year. But these products consume huge amounts of fossil fuel energy to get from those global locations to your corner supermarket.
- Dispose with disposables
Previous generations didn’t dream of single-use razors, forks, cups, bags, and food storage containers, but these days, you can find a plastic version of almost any object and then throw that object away after you use it.
Many of the environmental health issues today stem from toxins released into the environment by trash. Even trash that’s properly disposed of, such as that in a landfill, requires careful monitoring to ensure that dangerous chemicals don’t enter the surrounding environment.
When you make a purchase, consider the item’s life expectancy: How long can the item be used? Will it have more than one use? When you’re done with it, will it end up in the trash? Start investing in reusable products for the items you most often throw away.
- Plant seeds
Try growing your own food. Simply plant a few seeds in a corner of your yard or in a container on your porch or windowsill. You don’t need acres; a few square feet on a patio, along the driveway, or in a window box can provide enough space to grow edible herbs, fruits, and vegetables.
Recycle as much as possible! If your neighborhood or apartment complex doesn’t offer recycling pickup, either find a drop-off location or request the curbside service. Buying products labeled post-consumer lets companies know that recycling is the way to go!
For other items, such as CFLs, batteries, mobile/cellphones, and electronics, find an appropriate recycler. Many local stores accept used batteries over the counter, but be sure to ask where these materials go for recycling and avoid companies that ship electronic waste overseas for unregulated “recycling” and salvage operations.
- Resell and donate items
Items that you no longer need can get an extended life through resale and donation. By extending the life of any product, you help reduce dependence on disposable or cheaply made single-use products that end up in landfills.
Providing your items are in good condition and are compliant with safety standards there are many charity/thrift shops that you can donate to, so your items not only continue to be used but they benefit others by generating funds.
You can try reselling on Ebay or similar and make yourself some extra cash. There are also many reseller or goods-for-free pages on Facebook where you can get in touch with people in your own area and give your goods a new lease of life.
- Drink from the tap
Dependence on bottled water has added more than a million tons of plastic to the waste stream every year. One reason people rely on bottled water is because they believe it’s safer and better tasting than tap water. But most municipal water supplies in the U.S. provide safe, clean, fresh water (and many bottled waters are just bottled from city water supplies anyway).
If you don’t like the flavor of your tap water, consider the one-time investment in a filtration system. If you like the convenience of bottled water, purchase refillable bottles and keep one in your fridge, one in your car, and one at the office. Encourage your employer to install filters and offer glasses or reusable bottles at work, too.
- Save water
An easy way to live more sustainably is to conserve household water use. Consider installing water-efficient toilets or dual-flush toilets that let you choose whether to use a full flush (for solid waste) or half-flush (for liquid waste). Newer clothes washers can automatically sense the smallest level of water needed for each load.
Smaller changes, such as switching to water-saving shower heads and adding aerators to your sink faucets, are also effective ways to significantly reduce household water use.
To conserve water outdoors, use landscaping adapted to your local environment. When buying plants, look for drought-tolerant species and varieties and be sure to plant them in proper soil and sun conditions to reduce their need for excess watering. Set up sprinkler systems so they don’t water the sidewalk, the driveway, and other paved, impermeable surfaces.
- Rely less on your car
Using fossil fuels to support one person in each car on the road is clearly no longer sustainable. Investigate public transit options in your town or city, such as a bus or train or find out if your company operate carpool service for staff. When traveling close to home, walk or ride your bike.
Many workers in the UK now benefit from the Government Green initiative “Cycle to Work Scheme”. Cycles and safety equipment can be obtained through an employer as a salary sacrifice. This means there are substantial savings on average of 32% on the cost of equipment. So a cycle valued at £800 would actually only cost £544.
- Purchase fair-trade products
When you purchase items that are imported from all over the world — particularly coffee, cocoa, sugar, tea, chocolate, and fruit — look for the fair-trade certification. This designation tells you that these items were grown using sustainable methods of agriculture and that local people are receiving fair prices for the goods they produce.
Items that don’t have the fair-trade certification may have been produced unsustainably and may be the product of exploitative labor practices that don’t benefit the local people.
