Question

what is the main cause of global warming?

Answer 1

The main cause of global warming is the greenhouse gases like methane, carbon dioxide

Answer 2

THE MAIN CAUSES OF GLOBAL WARMING ARE:--

Deforestation

We clear forests for a huge number of reasons, from harvesting wood to make lumber or paper, to clearing land for cattle and pig ranching, to putting in vast tracts of monoculture crops: corn, wheat, palms. While crops may fix a small amount of carbon – removing it from the air and storing it in roots – it is nothing compared to the amount that trees can fix, or “sequester.”

Ranching

Ranching is devastating to our planet in more ways than one. In addition to necessitating the removal of all that valuable forestland, ranching also produces massive quantities of animal waste, which in turn produces lots of methane – a very harmful greenhouse gas

Industrial Farming

While organic farming practices can actually help reduce global warming, sequestering carbon through the growth of crops, it also has some seriously devastating side effects. For one thing, our industrial agricultural system requires a lot of fossil fuel. Shuttling fertilizers, equipment, seeds, crops and so on requires a tremendous amount of gas and diesel, especially when we’re shipping across the U.S. – or across the world.

Surface Warming

Global warming isn’t only a product of the harmful gases being pumped into the air. We are also making the surface of the planet hotter by paving over naturally cooler green spaces with asphalt and concrete, which hold much more heat than do living things. That heat is then reflected back into the atmosphere, back down to Earth, et cetera, in an endless loop of heating.

Fertilizers and Pesticides

These two common farming inputs are also deadly to the environment. Not only do they annihilate soil, and kill native plants, insects and animals, they pollute waterways and air. They are manufactured at huge plants which dump chemicals into the environment, including Global Warming villains carbon dioxide, methane and nitrous oxide.

Electricity Generation

We burn fossil fuel to produce electricity. Burning it generates heat and other output that turn turbines, gathering energy and storing it as electricity, which can be delivered out over the grid. We must invest in clean energies to stop the constant burning of fossil fuels.

Plastic Water Bottles

Plastic water bottles are shockingly bad for the environment. Even plastic bottlers themselves are starting to recognize the issue: “To make the 50 billion plastic PET bottles each year it takes 1 and a half million bottles of oil. That is enough oil to fuel 1 million cars for an entire year. That is only the oil that goes into the bottles.” It doesn’t include fuel to run the plants, prepare the water for bottling or distribute the bottles. Nor does it account for the greenhouse gases that plastic emits as it sits in landfill, not decomposing, for centuries.
