13. Work in pairs. Discuss the following quotations about ecological problems.

1. Nature pardons no errors. (R.W. Emerson. Essays)

2. Our remedies oft in ourselves do lie which we ascribe to heaven. (W. Shakespeare. All’s Well That Ends Well)

3. As soils are depleted, human health, vitality and intelligence go with them. (Bromfield Louis Writer (1896-1956)).

4. Only when the last tree is cut; only when the last river is polluted; only when the last fish is caught; only then will they realize that you cannot eat money. (Indian proverb).

  1. Man has lost the capacity to foresee and to forestall.  He will end by destroying the earth.  (Albert Schweitzer).

14. Read the interesting facts about nature and tell one of them to your groupmates.

  1. Some recent studies suggest that 30% of all natural species will be extinct by 2050 if current trend of biodiversity loss continues in the next few decades. 2. Though scientists are each year trying to improve the current inventories of species these inventories are always insufficient and incomplete to provide the fully accurate numbers of species that live in our planet. 3. Biodiversity loss if continues its current trend is likely to cause huge food shortage in years to come.

4. Scientists believe that according to the fossil records there have been five historical mass extinctions, and Earth is currently facing sixth mass extinction. 5. Biodiversity loss is not only happening on land but also in our oceans and seas, one of the main reasons for this is climate change that is not only increasing ocean temperatures but also makes oceans more acidic. 6. Invasive plants and animals are also one of the biggest threats to biodiversity. These invasive species compete with native species for food and resources which can lead to extinction of many native species.

  1. Fossil-fuel burning has contributed to most of the greenhouse gas emissions in the past 20 years. About three-quarters of the anthropogenic emissions of carbon dioxide to the atmosphere during the past 20 years have been due to fossil-fuel burning. Activities consuming fossil fuels include power generation, industrial/manufacturing processes, transport. The rest of carbon dioxide emissions are predominantly due to land-use change, especially deforestation.

  1. The decade of the 1990s was the warmest, and 1998 was the warmest year on record, since 1861. Scientists began systematically recording temperatures at specific locations on the earth's surface around the 1860s. Since then, 1998 has been the hottest year and the decade of the 1990s was the warmest. The increase in surface temperature over the 20th century for the Northern Hemisphere is likely to have been greater than for any other century in the last thousand years.
