Some people agree that human has damaged the earth other believe vice versa.
When we look at our earth from the time we were born to the present day, we can see lots of changes by own eyes due to rapid deforestation and industrialization. I feel that people keep themselves busy in order to fulfill their demands but do not care about environmental damages, extinction of animals and global warming which are threatening every one of us. Though some people think that our earth is being a nice place to live due to technological innovations leading to sophisticated life styles, I believe that there has been more damaged due to deforestation, industrialization, pollution and ...view middle of the document...
In addition, effect of deforestation is now tangible to everybody. We can see that many areas are flooded by increased sea level. For example, many developing countries such as India, Bangladesh, Nepal gets flooded every year and causes lots of devastation making many people homeless; and without food and sanitation. Furthermore, green house effects are gradually increasing due to Deforestation and Industrialization which in turn are responsible for global warming. Higher rate of melting of ice in Antarctica is the result of global warming.
The study, by 1,360 experts in 95 nations, said a rising human population had polluted or over-exploited two-thirds of the ecological systems on which life depends, ranging from clean air to fresh water, in the past 50 years.
"At the heart of this assessment is a stark warning," said the 45-member board of the Millennium Ecosystem Assessment.
Ten to 30 percent of mammal, bird and amphibian species were already threatened with extinction, according to the assessment, the biggest review of the planet's life support systems.
"Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fibre and fuel," the report said.
"This has resulted in a substantial and largely irreversible loss in the diversity of life on earth," it added. More land was changed to cropland since 1945, for instance, than in the 18th and 19th centuries combined.
UN Secretary-General Kofi Annan said the study "shows how human activities are causing environmental damage on a massive scale throughout the world,and how biodiversity -- the very basis for...
