diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life. FIND OUT 5 WAYS HOW TO HALT THE LOSS OF BIODIVERSITY 6. Deforestation: Our forests produce fresh oxygen and help in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and making that land available for residential, industrial or commercial purpose. FIND OUT 5 WAYS HOW TO STOP DEFORESTATION. 7. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton
All other types of buildings, like places of worship, fire stations, police stations, and laboratories, account for the remaining 10 percent of commercial building energy. 10 Picture 2.7 Energy use by type of building 2.5 Industrial and Manufacturing Energy Use The United States is highly industrialized. Industry accounts for about one-third of the energy used in the country. There are many different uses and a variety of different energy sources in the manufacturing sector. One main use is as boiler fuel, which means producing heat that is transferred to the boiler vessel to generate steam or hot water. Another use is as process heating, which is when energy is used directly to raise the temperature of products in the manufacturing process; examples are separating components of crude oil in petroleum
is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also cause acid rain, that destroyes plants, rivers, lakes and buildings. Acid rain can travel thousands of miles, so pollution in one country can become acid rain for another country. So how to avoid the worst? Lets talk about cars, which are the main means of transport in our everyday life, they are useful and take us to the place, where we want to go. But lets be honest, they have also negative aspects. Like heavy traffic in the morning, while you are going to work and in the evening, when you are about to go home. Cars also, like factories, produce poisoned gas in the air
oceans, and groundwater caused by human activities, which can be harmful to organisms and plants and for all of us. First, we have to talk about the causes of water pollution. Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers. Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Dumping of litter in the sea can also cause huge problems. Different items take different lengths of time to degrade in water. Oceans are polluted by oil on a daily basis from oil spills, everyday shipping and dumping. Secondly, it is very significant to know about dangers of water pollution. Virtually all types of water pollution are harmful to the health of humans and animals. Water pollution may not damage our health immediately but can be harmful after long term exposure.

Thanks to cleaner air people's can breathe better air. This is partly true, but taking up cycling instead of using a car is really more dangerous than use only cars. Thanks to taking up cycling traffic will go busier and messier. There is much different kind of movers in traffic and it makes traffic really dangerous. It is clear that it is not too dangerous. There are many cities where cycling is very popular, for example in Copenhagen. If this method will be chosen, city needs to build special cycling roads. Thanks to these roads traffic should be safer. More energy is used up taking items to recycling banks than the benefits gained from recycl

Wrappers, bottles and other trash are unfortunately a common site at many well-used beaches and rivers around the world.

The thing that bothers me the most in today's world is the lack of care. It is noticeable everywhere: in the streets, on television or even in relationships. If I had the power to change anything I would change the attitude of humankind considering the following issues.

I would change that. I
