Practices to Reduce Greenhouse Gas Emissions
- Increase production through herd health and breeding practices.
- Feed cattle based on nutrient needs.
- Composting.
- Include additives in manure to suppress unwanted biological activity.
- Implement manure storage covers and anaerobic digesters.
Meet the world's top destroyer of the environment. Livestock are responsible for 18 per cent of the greenhouse gases that cause global warming, more than cars, planes and all other forms of transport put together.
With every episode of gas and especially burping, cattle release methane, which is 23 times more harmful than carbon dioxide, the main greenhouse gas in car emissions. Besides cow's gas, their manure can be problematic.
A 2013 study by the U.N. Food and Agriculture Organization (FAO) estimated that total annual emissions from animal agriculture (production emissions plus land-use change) were about 14.5 percent of all human emissions, of which beef contributed 41 percent.
Yes, driving cars is no good, but meat production is unexpectedly worse for the environment. Besides all of the fertilizer and cow waste products that release methane, meat unfortunately has to be transported in refrigerated trucks from feedlots to slaughterhouses to processing centers to your local grocery store.
Meat – or more specifically, 'industrial meat' – is bad for the planet. Through its meat production, JBS produces around half the carbon emissions of fossil fuel giants such as Shell or BP, and is driving deforestation in the Amazon. The industrial meat system requires a huge amount of land to sustain itself.
Q: What causes global warming? A: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface. That's what's known as the greenhouse effect.
In fact, carbon dioxide, which is blamed for climate warming, has only a volume share of 0.04 percent in the atmosphere. And of these 0.04 percent CO2, 95 percent come from natural sources, such as volcanoes or decomposition processes in nature. The human CO2 content in the air is thus only 0.0016 percent.
Overview
- Transportation (28.2 percent of 2018 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions.
- Electricity production (26.9 percent of 2018 greenhouse gas emissions) – Electricity production generates the second largest share of greenhouse gas emissions.
5 Causes of Global Warming
- Greenhouse Gases Are the Main Reasons for Global Warming.
- Cause #1: Variations in the Sun's Intensity.
- Cause #2: Industrial Activity.
- Cause #3: Agricultural Activity.
- Cause #4: Deforestation.
- Cause #5: Earth's Own Feedback Loop.
The Top 10 Causes of Global Warming
- Power Plants. Forty percent of U.S. carbon dioxide emissions stem from electricity production.
- Transportation. EPA reports state that thirty-three percent of U.S. emissions come from the transportation of people and goods.
- Farming.
- Deforestation.
- Fertilizers.
- Oil Drilling.
- Natural Gas Drilling.
- Permafrost.
Corporations produce just about everything we buy, use, and throw away and play an outsized role in driving global climate change. A recently published report identified that 100 energy companies have been responsible for 71% of all industrial emissions since human-driven climate change was officially recognized.
These countries produce the most CO2 emissions
- Saudi Arabia.
- Iran.
- Germany.
- Japan.
- Russian Federation.
- India. • CO2 emissions from fossil fuel (2017): 2,466.8 million metric tons.
- USA. • CO2 emissions from fossil fuel (2017): 5,269.5 million metric tons.
- China. • CO2 emissions from fossil fuel (2017): 9,838.8 million metric tons.
Admittedly, air transport is extremely polluting – but so are cars. Air traffic represents less than 2-3% of the global CO2 emissions whereas road traffic accounts for around 10% of these direct emissions. Still, planes remain among the most polluting means of transport, together with cars.
There are three routes to reducing GHGs from transportation: increasing the efficiency of vehicle technology, changing how we travel and transport goods, and using lower-carbon fuels.
Cars and trucks that transport goods and people create approximately 38% of total climate change emissions. Driving green saves money and reduces greenhouse gas emissions.
Burn fuel cleaner
- Keep your vehicle well-tuned and tires inflated properly to reduce exhaust emissions.
- Combine errands into one trip — cars pollute less when they are warmed up.
- Avoid idling — idling exhaust contains more pollutants than running exhaust.
A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO2.
Transport is Australia's third largest source of greenhouse gas emissions (96MtCO2e per year, 17% of total emissions) (Australian Government 2017a). Transport emissions have grown more than any other sector, increasing nearly 60% since 1990 (Australian Government 2017a).
How You Can Stop Global Warming
- Speak up!
- Power your home with renewable energy.
- Weatherize, weatherize, weatherize.
- Invest in energy-efficient appliances.
- Reduce water waste.
- Actually eat the food you buy—and make less of it meat.
- Buy better bulbs.
- Pull the plug(s).
The environmental impact of transport is significant because transport is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide.

Reforestation is the activity among these four options that does not contribute to global warming. It is the act of planting more trees and restoring the forest and woodlands. It mitigates global warming by enhancing biological process thru reduction carbon dioxide, a greenhouse gas that affects global warming.
The main greenhouse gases are:
- Water vapor.
- Carbon dioxide.
- Methane.
- Ozone.
- Nitrous oxide.
- Chlorofluorocarbons.
Tens of thousands of scientists in more than a hundred nations have amassed an overwhelming amount of evidence pointing to a clear conclusion: Humans are the main cause. We're the ones who burn fossil fuels, produce livestock and clear trees, increasing the amount of heat-trapping gases in the atmosphere.
The various greenhouse gases are carbon dioxide, methane, chlorofluorocarbon, ozone, nitrous oxide, and water vapor. Hence the gas which is not a greenhouse gas is nitrogen and the correct answer for the given question is option d).
Methane is a potent greenhouse gas and the second biggest contributor to human-caused global warming after CO2. Per unit of mass, methane is 84-86 times stronger than CO2 (pdf) over 20 years and 28-34 times as powerful over 100 years.
Extra carbon dioxide in the atmosphere increases the greenhouse effect. More thermal energy is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. This increase in the Earth's temperature is called global warming .
