Of course we can! But every action you do, affects the earth. Learn how to save the earth before taking actions. If not you will be...(example)burning down some part of the forest for growing crops while thinking "I can save the earth!".How to save the earth? You can save ELECTRICITY, burn less fuels(example:wood,oil,etc.), etc. One action can affect the whole earth! Example: burning down some part of the forest. Burning requires OXYGEN that WE NEED and produce CARBON DIOXIDE which we can also produce through repiration. Too much carbon dioxide in the air is not good at all.
This is because, the carbon dioxide will rise to the air as it is produced, then traps heat. Heat comes into the earth and goes out of the earth. When heat reaches the earth, the carbon dioxide will trap some of the heat while it goes out of the earth. As there is MORE carbon dioxide to trap HEAT, LESSER heat will travel back into the space. Thus, more heat will be trapped in EARTH and the temperature of the earth will INCREASE as there is MORE heat.

Causes of the change of climate
1. Rising of temperatures: Average global temperature have risen in this century. This is because of that the greenhouse gases build up with carbon dioxide. It affects human lives and animal lives.
2. Rising sea levels: Sea levels are rising hastily and made till low lying islands to have severe floods.
3. Melting ice: Antartica are affected by the hot weather as it has ice. Ice will melt, and animals living on the Antartica will die due to the weather. There will be lots of floods, which causes sea level to rise. Loss of Arctic ice also frees methane. It is a greenhouse gas from seas and soils which will worsen global warming.
4. Dying seas: Seas that has fishes and other living things growing in it will die easily as the seas absorb carbon dioxide which is turning the waters MORE acidic. Warmer waters have also killed a quarter of the world's coral reefs.
5. Severe storms: The frequency of downpours and the power of hurricanes have increased so dramatically that "100-year storms" are striking some areas once every 15 years.
6. Parched earth: Some areas were experiencing droughts, such as El Nino. High temperature bring less snow to Himalayas, causing that area to have lesser water supplies for people living downstream.
7. Smaller harvests: Farmers have complaint that the dry weather have made their crops 50 percent less yield.
8. Earlier springs: Japan's cherry blossom season came five days early this year and a week earlier than the average for the past three decades.
9. Spread of diseases: diseases and their carriers can travel easily because of warmer temperatures.
10. Endangered species: The most affected victim is the polar bears. They live in icy cold place. As the ice melts, they will lose their habitat.

Ways to produce electricity
Electricity is the one of the source we need in our daily lives. Producing electricity through burning fuels also harms the environment! The more electricity we use, the more the environment gets harmed.
There are different ways to produce electricity, but there are pros and cons. Yes, you can burn fossil fuels to produce electricity, but it is too harmful to the environment.Ways to cut carbon dioxide to produce electricity:
- Use solar power
- Use wind power
- Use hydropower
- use geothermal power
- use Nuclear power
- use biofuels
- use carbon capture and storage
- do carbon trading
- geoengineering
- use osomotic power

Having HIV/AIDS instead of big brain disease? Which is MORE serious? Brain disease, of course! 2 boys with brain disease werebeing inserted with HIV genes to cure the brain disease. This is so called "exchange", but exchange for a better disease. As i think that HIV is better than brain disease, and not as serious as brain disease, altough it causes aids, it's very good exchange.
Everyone was shocked by the "School Closed". Pupils who decided to take on private schools can only see their money, busily flying away to a big fox. Cheaters... They were cheated by the "schools" for their money. Their money had gone to a waste. But at least they bought a lesson of not to always believe private schools!
