nature, habitat - reduce, reuse, recycle

Reduce, Reuse and Recycle : The new way to go

nature, habitat - global warming

Effects of global warming

Evidence of observed climate change includes rising sea levels, and decreased snow cover in the Northern Hemisphere.Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in [human greenhouse gas] concentrations". It is predicted that future climate changes will include further global warming , sea level rise, and a probable increase in the frequency of some extreme weather events. Signatories of the United Nations Framework Convention on Climate Change have agreed to implement policies designed to reduce their emissions of greenhouse gases.

How to reduce global warming
    -3 main things to reduce global warming -Reduce, Reuse, Recycle
You can do your part to reduce waste by choosing reusable products instead of disposables. Buying products with minimal packaging (including the economy size when that makes sense for you) will help to reduce waste. And whenever you can, recycle paper, plastic, newspaper, glass and aluminum cans into the recycle bins. If there isn't a recycling program at your workplace, school, or in your community, ask about starting one. By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually!

nature, habitat - ways to conserve natural habitats

S A V I N G  T H E  E A R T H
In order to save forests from deforestation, we can reuse papers by using them fully before throwing them away. This will help by reducing the number of trees being cut down that results in animals losing their habitats. After using the papers fully, we can throw them in the recycling bins where after they will be able to reuse its purpose all over again, enabling less wastage of paper.
We can save the Earth by not turning on the air-conditioners as often as switching on the air-conditioners need lots of electricity. We can use the fan instead as the fan uses less electricity than air-conditioners. If people continue to use air-conditioners too often, we will run out of fuels soon. Because of human greed, people created many things such as the computer; which needed much electricity. But in exchange, many things are more convenient to us with the computer.We people created many things to make our life more convenient, but those things are usually bad to Earth as they use much of our natural resources.We should create more things that are good to Earth so that we can save it.

nature, habitat - global warming




The increase in the average temperature of Earth’s near-surface air and oceans is known is global warming.

Over the last 50 years, almost 100% of the observed temperature increase has been due to the increase in the atmosphere of greenhouse gas concentrations such as water vapour, carbon dioxide, methane and ozone. Greenhouse gases are gases that contribute to the greenhouse effect. The burning of fossil fuels that leads to the emission of carbon dioxide is the largest contributing source of greenhouse gases.

The effects of global warming are the increase of temperature on earth by about 3 to 5 degree Celsius by the year 2100. The sea levels will also rise bt at least 25 metres by then.

nature, habitat - soil erosion

credits to google.

Adding on to wanjia's post, deforestation affects the growth of other plants as soil erosion would occur. The roots of the trees secure the soil, but without roots the soil would divide themselves unevenly and affect the growth of other plants. Many living things would die as they live on land and their habitat is being destroyed. Also, without the other plants to beautify our surrounding, the world would look very dull. But of course, the cause of soil erosion is not only deforestation, acid rain is also one of the causes. What causes rain to be acidic ? For instance, acidic sulphur is being produced by factories, the sulphur is being washed into rivers, drains, etc and is evaporated. This vicious cycle repeats and thus acidic rain is created. Firstly, people should do re-forestation, secondly, they should encourage factories to dispose their waste in a correct and proper manner. With that, i end my post (:

nature, habitat - deforestation


 <<< in Madagascar


The Earth is in danger now... Many natrural resources such as, tress had been cut down for papers , desks and many other things... We must be gratetful to trees as they provide us oxygen,food and shelter. If we do not have trees, we will not be able to survive. But human not only did not thank them, but cut them down for human uses. We must really save the Earth as if we did not, human will be extinct one day! Not only the human but the animals will too be extinct as they do not have food to eat and home to stay as their habitat is being destroyed. So we must SAVE THE EARTH!!! n_n

nature, habitat - floodings













Lately, because of global warming, the environment on Earth has changed drastically. Some after effects of global warmings are spread of diseases, warmer waters thus more hurricanes, increased probability and intensity of drought and heat waves, economics consequences,and polar ice caps melting. Focusing on warmer waters leading to hurricanes, it may result in floods in low-lying areas and places near the beach.
 Recent floodings in Australia have been disastrous! Two weeks before the flooding, Cyclone Tasha dumped alot of water on Queensland.Hundreds of thousands of people in an area the size of France and Germany combined have been affected. This is an example of the deadly impact on global warming.
