write briefly the preventive measures of global warming
Answers
What’s the single biggest way you can make an impact on global climate change? “Talk to your friends and family, and make sure your representatives are making good decisions,” Haq says. By voicing your concerns—via social media or, better yet, directly to your elected officials—you send a message that you care about the warming world. Encourage Congress to enact new laws that limit carbon emissions and require polluters to pay for the emissions they produce. “The main reason elected officials do anything difficult is because their constituents make them,” Haq says. You can help protect public lands, stop offshore drilling, and more here.
2. Power your home with renewable energy.
Choose a utility company that generates at least half its power from wind or solar and has been certified by Green-e Energy, an organization that vets renewable energy options. If that isn’t possible for you, take a look at your electric bill; many utilities now list other ways to support renewable sources on their monthly statements and websites.
3. Weatherize, weatherize, weatherize.
“Building heating and cooling are among the biggest uses of energy,” Haq says. Indeed, heating and air-conditioning account for almost half of home energy use. You can make your space more energy efficient by sealing drafts and ensuring it’s adequately insulated. You can also claim federal tax credits for many energy-efficiency home improvements.
4. Invest in energy-efficient appliances.
Since they were first implemented nationally in 1987, efficiency standards for dozens of appliances and products have kept 2.3 billion tons of carbon dioxide out of the air. That’s about the same amount as the annual carbon pollution coughed up by nearly 440 million cars. “Energy efficiency is the lowest-cost way to reduce emissions,” Haq says. When shopping for refrigerators, washing machines, and other appliances, look for the Energy Star label. It will tell you which are the most efficient.
5. Reduce water waste.
Saving water reduces carbon pollution, too. That's because it takes a lot of energy to pump, heat, and treat your water. So take shorter showers, turn off the tap while brushing your teeth, and switch to WaterSense-labeled fixtures and appliances. The EPA estimates that if just one out of every 100 American homes were retrofitted with water-efficient fixtures, about 100 million kilowatt-hours of electricity per year would be saved—avoiding 80,000 tons of global warming pollution.
6. Actually eat the food you buy—and make less of it meat.
Approximately 10 percent of U.S. energy use goes into growing, processing, packaging, and shipping food—about 40 percent of which just winds up in the landfill. “If you’re wasting less food, you’re likely cutting down on energy consumption,” Haq says. And since livestock products are among the most resource-intensive to produce, eating meat-free meals can make a big difference, too.
7. Buy better bulbs.
LED lightbulbs use up to 80 percent less energy than conventional incandescents. They’re also cheaper in the long run: A 10-watt LED that replaces your traditional 60-watt bulb will save you $125 over the lightbulb’s life.
8. Pull the plug(s).
Taken together, the outlets in your home are likely powering about 65 different devices – an average load for a home in the U.S. Audio and video devices, cordless vacuums and power tools, and other electronics use energy even when they're not charging. This "idle load" across all U.S. households adds up to the output of 50 large power plants in the U.S.So don't leave fully charged devices plugged into your home's outlets, unplug rarely used devices or plug them into power strips and timers, and adjust your computers and monitors to automatically power down to the lowest power mode when not in use.
9. Drive a fuel-efficient vehicle.
Gas-smart cars, such as hybrids and fully electric vehicles, save fuel and money. And once all cars and light trucks meet 2025’s clean car standards, which means averaging 54.5 miles per gallon, they’ll be a mainstay. For good reason: Relative to a national fleet of vehicles that averaged only 28.3 miles per gallon in 2011, Americans will spend $80 billion less at the pump each year and cut their automotive emissions by half. Before you buy a new set of wheels, compare fuel-economy performance here.
10. Maintain your ride.
If all Americans kept their tires properly inflated, we could save 1.2 billion gallons of gas each year. A simple tune-up can boost miles per gallon anywhere from 4 percent to 40 percent, and a new air filter can get you a 10 percent boost.
11. Rethink planes, trains, and automobiles.
Choosing to live in walkable smart-growth cities and towns with quality public transportation leads to less driving, less money spent on fuel, and less pollution in the air. Less frequent flying can make a big difference, too. “Air transport is a major source of climate pollution,” Haq says. “If you can take a train instead, do that.”
You will avoid rising prices at the gas pump and dramatically reduce your daily carbon emissions by selling your car. Buying a hybrid vehicle is one thing, but you’re still highly dependent upon fossil fuel for energy.
You will become healthier by riding a bicycle. Curb your addiction to cars, sell your vehicle, and become more mobile by using a bike, or public transportation such as the bus, subway, or train. There may even be carsharing programs in your city. There are numerous transportation alternatives to owning and driving a car.
If your daily commute is more than a few miles away from your home, you may want to consider moving to a closer location to your job. Living car-free is a liberating experience and you will learn to prevent global warming on your way to work.
2.) Eat fresh, local foods for a healthy environment and youThere has been an influx of organic food in supermarkets over the past several years. But of equal importance to consider is where that food is coming from. For example, how much of the produce in your supermarket is being transported halfway around the world? Check the stickers on those apples and peaches and you’ll see ” Produce of Chile”, “Mexico”, or “China”. Also important to note: how much of that food is actually in season? The transportation of food is a major contributor to greenhouse gases.
Easy ways for you to get low carbon food are:
Buying things that are actually in season.Buying locally-grown fruits and vegetables at farmers markets.Joining a CSA.You’ll massively reduce the carbon from your food if you follow the above advice. Plus, eating locally-grown, fresh foods is not only better for the planet, it’s healthier for you, too.
3.) Learn how to reduce your home’s carbon footprintDo you realize that modern houses are built using synthetic products and other materials with high embodied energy? Sadly, this means that modern homes are huge contributors to global warming. For example, concrete is (amazingly) the second most consumed material on earth, right behind water, and it takes a huge amount of energy to produce it. Not only that, the manufacturing process is highly polluting.
You can lower your energy bills with a home that is designed for maximum energy efficiency. One of the most simple things to consider learning about is passive solar design. Passive solar homes feature smart design considerations that can dramatically decrease the need for active energy heating and cooling systems. In other words, passive solar homes stay cooler in the summer, and warmer in the winter with lesser need for air conditioning and heating. Greater energy efficiency equals a lesser carbon footprint.
Explode your conceptions of what a home can really be. You can take a workshop on how to build a straw bale home or a cob building, if you want to take it even further. Both of these natural building techniques stress the use of local and natural building materials, such as straw bales, sand, and clay. Natural building is an important movement towards a lower impact and environmentally sustainable lifestyle.
Together, we have the power to fight global climate change.
