species extinction
• There are 75 species becoming extinct every day.and three species extinct every hour in the world. • U.S well-known biologist Stuart Pimm in Duck University believes that if such a rate continues,by 2050,the current quarter or the hall of the species will be extinct or endangered.

Global warming
Global warming has become perhaps the most complicated issue facing world leaders. On the one hand, warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests. On the other, the technological, economic and political issues that have to be resolved before a concerted worldwide effort to reduce emissions can begin have gotten no simpler, particularly in the face of a global economic slow down
• • • • • • Climate change Effects of global warming are causing the temperature of the Earth to slowly rise, causing massive global changes to our natural environment. Rising sea level Effects of global warming are rapidly melting glaciers around the globe, causing a rising sea level and possibly coastal flooding and other weather problems in the future. Ecosystem changes Effects of global warming are changing certain ecosystems throughout due to temperature fluctuations. Animals and plants are being forced to adapt to this, and as a result are dying off. Breakdown of the Ozone layer Effects of global warming are creating holes in the ozone layer, primarily from human use of products that emit toxic chemicals. The ozone layer absorbs UV radiation from the sun, the holes are causing amounts of toxic chemicals present in our breathing air to increase at a rapid rate.
