Why are cloth bags better than plastic bags?
Scientists estimate that it takes upwards of 500 years for a plastic bag to decompose, filling up landfills at an alarming pace. Plastic bags are also dangerous to animals and sea creatures who accidentally ingest them.
Why does switching off heating help the environment?
Switching off heating helps the environment by reducing energy consumption, which in turn decreases greenhouse gas emissions from the burning of fossil fuels. It also helps conserve natural resources and reduce overall environmental impact associated with energy production.
What is the carbon footprint of a 2x4 lumber?
The carbon footprint of a 2x4 lumber depends on various factors such as the type of wood, sourcing, processing, and transportation. On average, the production of lumber generates about 1.9 kg of CO2 per kg of wood. However, sustainable forestry practices and using local sources can help reduce the carbon footprint associated with 2x4 lumber.
Greenhouse gases trap the heat rising from the warmed surface of the earth. Hence, increasing the temperature of earth. This is called the greenhouse effect.
If extra greenhouse gases are added, then we have an accelerated greenhouse effect, which causes global warming.
Are plastics responsible for utilizing a major share of the world's oil or hydrocarbon resources?
Though petrochemicals are a critically important source of materials for plastics (and for many, many other products and industrial feedstocks), most oil and hydrocarbon resources (coal, gas, etc.) are used as fuels. It's that simple.
Global warming - fact or fiction?
Global warming is a fact that is backed by overwhelming scientific evidence. The Earth's average temperature has been increasing over the past century primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes, leading to an increase in greenhouse gases in the atmosphere. This phenomenon has wide-ranging impacts on the environment, contributing to rising sea levels, extreme weather events, and disruptions to ecosystems.
What precautions should you take for global warming?
The major precaution is to produce low CO2. CO2 is the main cause of global warming as it increases the green house effect which leads to trapping up of the heat energy near the surface of the earth and makes the temperature rise.
What are the Disadvantages of aluminum?
* Far more expensive that steel. * Limited to certain geometric features using economical processes. * Abrasive to tooling (aluminum oxide is very abrasive). * Difficult to weld. * Prone to severe spring back.
The log homes are excellent examples to Eco-Firendly housing. The homes are completely made of wood like Northern White Cedar. The main advatnage of these eco-friendly log homes is that they have less CO2 emmisions. Moreover, you can save huge cash spent on energy bills as these log homes require less airc-condtioning. The log homes made of Northern White Cedar require less maintenance when compared to the traditional homes. All these make the log homes "The Eco-friendly housing".
Outside of that, any home that is designed to be energy efficient. Facing and orientation is very important, you want to maximise the sun in the winter so in the US you want your living areas (where you spend more time in the day) to face the South, while in Australia, you would want it facing to the North. You would also use environmentally friendly materials such as FSC certified timber and adapt thermal mass to help trap heat in the home.
What you should do if any one is spoiling the environment?
If someone is spoiling the environment, you can address the issue by educating them on proper environmental practices, contacting local authorities if necessary, and participating in community clean-up efforts to counteract the damage. It's important to communicate the importance of protecting the environment and encourage positive behavior changes.
For millennia humans have left their mark on the world's forests, although it was difficult to see. By the twenty-first century, however, forests that humans once thought were endless are shrinking before their eyes. Forests are not only a source of timber; they perform a wide range of social and ecological functions. They provide a livelihood for forest dwellers, protect and enrich soils, regulate the hydrologic cycle, affect local and regional climate through evaporation, and help stabilize the global climate.
What do trees contribute to Earth?
Because they give off a LOT of oxygen!
Trees help the earth by giving us oxygen and if we didn't have trees we wouldn't have oxygen and if we didn't have oxygen then there would be no food... it would be like living in space.
What is the greenhouse effect and how can you prevent it?
The Greenhouse Effect:
Greenhouse gases, such as water vapor, carbon dioxide, methane etc., move in and out of the atmosphere. They trap some of the heat radiated out from the Earth that would normally move out into space. This is called the greenhouse effect. It is natural, and is caused by the earth's carbon and water cycles and the heat from the sun. Without this warming we would be a cold dead planet.
The Enhanced Greenhouse Effect:
Since the beginning of the Industrial Revolution, 260 hundred years ago, we have been burning fossil fuels, initially coal, then oil and natural gas in much greater quantities than before. Fossil fuels contain carbon that has been hidden away for millions of years. Burning fossil fuels is adding extra Carbon Dioxide to the greenhouse gases in the atmosphere, much more than the normal carbon cycle can manage, and is making the atmosphere and the planet warmer. Increased demand for food and red meat has led to massive deforestation for grazing land. Trees no longer act as a valuable soak or sink for carbon dioxide. More cattle mean more methane expelled into the atmosphere. Methane is a much more dangerous greenhouse gas than CO2. This process is called the enhanced, or accelerated greenhouse effect.
When the sun's rays enter earth's atmosphere, but don't exit. Too much of this causes Global Warming.
A: One of the main causes of Global Warming is the Green house effect. When the emission of infra-red radiation in the atmosphere warms a planet's surface, it is known as the Green House Effect. The Greenhouse effect is a natural phenomena occurring on planet Earth
One of the man-made causes of the Green House effect is deforestation. Deforestation increases the amount of carbon-dioxide in the atmosphere. Also, due to the disappearance of trees, photosynthesis cannot take place. Deforestation causes of the greenhouse effect. Deforestation is rampant today due to the increase in human civilization. The levels of deforestation have increased by about nine percent in recent times. Also, the burning of wood causes it to decay,therefore releasing more carbon-dioxide into the atmosphere.
Greenhouse Gases also can be released into the atmosphere due to the burning of fossil fuels, oil, coal and gas. These materials are used increasingly and rampantly in Industries. Therefore Industries are also a major cause of the Greenhouse Effect.
Carbon Dioxide and other pollutant gases in the atmosphere prevent trapped heat from escaping into space.
How do the different parts of the water cycle fit together?
The water cycle is a continuous process where water evaporates from bodies of water, condenses in the atmosphere to form clouds, precipitates as rain or snow, and eventually flows back into oceans, rivers, and lakes. Each step in the cycle is interconnected and contributes to maintaining Earth's water balance.
How do parks and other green space in the city help reduce the urban heat island effect?
Parks and green spaces in the city help reduce the urban heat island effect by providing shade, promoting evapotranspiration, and reducing surface temperatures through vegetation and soil moisture. Trees and plants in these areas also help lower air temperature by releasing water vapor through the process of transpiration. Additionally, they can enhance airflow and create a cooling effect through shading and reducing the amount of heat-absorbing surfaces like concrete and asphalt.
What are the harmful effects of global warming?
Where is the most water on earth?
Oceans contain the most water because they cover the majority of the earth's surface and are often very deep. I would say the pacific ocean holds the most water of any one specific place on the planet.
Do energy efficient bulbs really reduce an electric bill?
Yes
A 100watt light bulb left on for 10 hours will use a much electricity as a 1 Kilowatt fire left on for one hour.
An energy efficient light bulb giving out the same amount of light as a 100watt bulb, only actually uses 20watts of electricity. That is 1/5th of the electricity, it will need to be on for 50 hours to use as much as a 1 Kilowatt fire left on for one hour. This will reduce your electric bill but the bulbs are more expensive than old 100watt bulbs (but the energy efficient bulbs last 6-8 times longer! so this balances out).
What countries have banned the use of plastic bags?
I know some countries have. England have not yet but they are starting to give out the bags for life so England may stop having plastic bags.

What are some short term effects of global warming?
Short term effects of global warming are:
1) Abnormally warm temperatures in the Winter and Summer months in various areas of the planet (actually throughout the year, but most easily contrastable in those seasons)
2) Deaths of certain forms of life that are not as adaptable to such temperature changes
3) Increases in glacial and ice cap melting, producing increases in sea level
4) Deaths of certain forms of life due to (3)...such as coral, which can only survive in certain pH levels, which changes in the sea as more fresh water is introduced into the oceans due to Arctic/Antarctic ice melting
5) Increases in the severity of certain storm patterns (such as tropical cyclones) and even local weather patterns
6) Increases in drought conditions in various areas
How does the greenhouse effect affect farmers?
The greenhouse effect can lead to changes in temperature and precipitation patterns, affecting crop growth. Warmer temperatures can alter the growing seasons and pest patterns, while changes in precipitation can impact water availability for irrigation. Extreme weather events like droughts or storms can also disrupt farming activities.
How would a drought affect green algae?
A drought can affect green algae by reducing water availability, which can lead to dehydration and stress in the algae. This can impair their growth, reproduction, and overall fitness. Additionally, a prolonged drought can lead to habitat loss for green algae as water sources dry up.
How much carbon dioxide is needed to fill a party-sized balloon?
I've just been trying to find the answer to this too. After coming across several different articles where people used different calcuations the answer seems to be about 10 grammes or 1 cu ft. depending on whether you want weight or volume.
So 1 tonne of CO2 = 100,000 balloons full.
Which make my yearly driving total, er, 250,000! Or our family total abut 1.1 million... Yikes! A bit easier to picture it now.
Imagine if we had waste collections for all our CO2 emissions that were in baloons: you'd need a truck at your house every day and assuming you get 20 balloons per bin, about 150 bins emptied - unless of course it was compressed first ;-)
What are the ingredients in bicarbonate of soda?
Bicarbonate of soda consists of only one ingredient, which is sodium bicarbonate. It is a white solid that is commonly used in baking as a leavening agent to help baked goods rise. Additionally, it has various household uses, such as cleaning and deodorizing.
Why energy considered a renewable resource?
That depends on where the energy comes from. Say the heat from the sun is a renewable source. Electricity fro m solar cells to a large extent is a renewable source as is wind power and wave or tidal power. If you have to use coal oil or uranium to get no.
