I think i have completed the homewokr for you successfully so give me 10 pointsWhat are various environmental problems our world is facing?Invasive species that get loose on the wrong continentWhat are various environmental problems our world is facing?
1) Chopping trees

2) Spitting on road side... is contagious.

3) Pollution

4) Disobeying traffic rules...

5) Disposing the waste



I can think only this much. If these r set right... half the problem would be solved... Don't u think so?What are various environmental problems our world is facing?Overpopulation, Overdrawing from the natural resources(assets of our future generations), unnecessary consumptions in daily life, excessive burning of fossil fuel, ever decreasing plantation{forest} area, overurbanization, wastage on the weapons and lack of love for nature in every human beingWhat are various environmental problems our world is facing?
I would say global warming is the biggest problem our world is facing. Here's some info from http://www.ncdc.noaa.gov/oa/climate/glob鈥?/a>



The greenhouse effect is unquestionably real and helps to regulate the temperature of our planet. It is essential for life on Earth and is one of Earth's natural processes. It is the result of heat absorption by certain gases in the atmosphere (called greenhouse gases because they effectively 'trap' heat in the lower atmosphere) and re-radiation downward of some of that heat. Water vapor is the most abundant greenhouse gas, followed by carbon dioxide and other trace gases. Without a natural greenhouse effect, the temperature of the Earth would be about zero degrees F (-18掳C) instead of its present 57掳F (14掳C). So, the concern is not with the fact that we have a greenhouse effect, but whether human activities are leading to an enhancement of the greenhouse effect.

Top of Page Are greenhouse gases increasing?



Human activity has been increasing the concentration of greenhouse gases in the atmosphere (mostly carbon dioxide from combustion of coal, oil, and gas; plus a few other trace gases). There is no scientific debate on this point. Pre-industrial levels of carbon dioxide (prior to the start of the Industrial Revolution) were about 280 parts per million by volume (ppmv), and current levels are about 370 ppmv. The concentration of CO2 in our atmosphere today, has not been exceeded in the last 420,000 years, and likely not in the last 20 million years. According to the IPCC Special Report on Emission Scenarios (SRES), by the end of the 21st century, we could expect to see carbon dioxide concentrations of anywhere from 490 to 1260 ppm (75-350% above the pre-industrial concentration).What are various environmental problems our world is facing?Major and serious problem is Global warming.What are various environmental problems our world is facing?

First the old ones:



Acid Rain - This one seems to have disappeared from the vogue over the decades. It was an early 70's issue and the polluters causing it have largely cleaned up their act.



Love Canal, Lake Erie, Sydney Tar Ponds - more classics from yesterday. Not all problems are fixed, but progress has been made.



Global Warming - This one has been the flavor of the month for years now, since before The Day After Tomorrow in 2004, but has really taken the front seat since then. Thanks Al.



Ozone Depletion - The issue came up in the 80's and the reality is now.



Call it a very general overview. The monthly articles available at this page http://www.stuffintheair.com/earth-scien鈥?/a> could help keep you up to date.
