From time to time people must remember how much damage can humankind cause to the world by polluting the air and waters, wasting energy sources, exterminating forests, acting indifferent to endangered species of animals and plants.
It would be a sad task to list all the kinds of living beings which could disappear (or had already disappeared) from the face of the Earth because of the irresponsibility of the human race.
Human does not spare its own kind, either: we all must face the consequences of global warming (intemperate weather, storms, and draught); the smog above the cities and the poisons getting to the soil and to the waters endanger our health and life.
We have heard many times that global warming is caused by carbon dioxide emission, and the poisonous garbage (that could not be composted) can cause a terrible damage.
Fortunately environmentalists try to point out our personal responsibility, and try to get people to save energy, use renewable energy sources and local sources, decrease garbage production. There are interesting posts about the subject on the link below:

Every country of the world is affected by the environmental pollution, the global warming emanating from the greenhouse effect; the consequences - droughts, flows, intemperate weather, melting of the ice of the polar regions, sinking of the fresh waters - overtake the inhabitants of all continents alike.
Nowadays one billion inhabitant of the Earth drink unsafe water.
Growing industry and global warming make a tragic influence on water on Earth.
Fresh water makes up about 2,5% of water on Earth. Over three quarters of it is tied up in polar ice cups and glaciers. Lakes, rivers and ground water makes up only a little fraction.
75% of fresh water is used by agriculture and stock-raising and 14% is used for industrial purposes.
Due to the climatic change, glaciers begin to melt. Ice of the Northern Pole can melt wholly by 2040.
At the Lena River, the number of the lakes and moors of summer tundra decreased with 10%.
Evaporation of lakes and seas increases permanently, that is why Baikal, Aral, Manchar and Chad Lakes almost have been dried up (the latter was one of the biggest lakes of the world some decades before; by now it has lost about 95% of its surface)
Global warming did not spare Colorado, Rio Grande, Chari, Logone, Jialing and Tiger Rivers either. Water level of Jangce and Yellow River is lower than ever before.
Surface of Dead Sea is decreasing year by year.
Snow-line of Kilimanjaro and Fuji got higher during the last years.
Intemperate weather, floods, drought, increasing price of food originate in global warming.
According to experts of UN, drinking water will be more expensive than gold by the end of this century.
What can we do about it:
- Produce utility waste instead of garbage
- Do not produce too much plastic garbage (plastic bags, bottles)
- Collect the garbage selectively
- Produce reusable waste instead of garbage
- Drink tap water instead of table waters
- Save energy: take care of the lagging of your home, have the dripping taps fixed,
- Turn off electric appliances when you do not use them. Switch off the television and the computer if you do not use them
- Do not leave the lights on in empty rooms
- Use energy-efficient light bulbs. (Only one energy-efficient bulb can reduce carbon dioxide emission 400 kg.)
- Eat food and buy products that does not need chemicals during its production
- Walk, ride a bycicle or travel by mass transporting vehicles instead of drive a car.
- Prefer domestic products, things made at nearby areas
- Use redeemable, long-term durability products (eco-friendly light bulbs, eco-friendly shopping bags) instead of disposable ones made for single use
- Do accept responsibility for the well-being of the animals and plants in our surroundings
The test on the link below can show us how big our "ecological footprint" is - which means how much do we care about our environment.
