  1. Ecology Done by baranovalice , grade 6

  2. Carbon dioxide • Carbon dioxide has an effective lifetime of about 100 years.   This means that any changes in the atmosphere will take along time to develop.   If we cut down on the amount of carbon dioxide we use, the rate of climate change will slow down.

  3. CARDONE DIOXIDE

  4. WEATHER CHANGES • Weather changes also depend on the type of pressure. Low pressure tends to bring in cloudy conditions and rainfall. On the other hand, high pressure tends to bring in fair weather. Tropical low pressures do not have fronts. This keeps the air mild even when the weather gets unsettled.

  5. DISAPPEARING AND RARE

  6. DISAPPEARING AND RARE • Thousands of tigers have been killed in the last 50 years because their habitat has been destroyed by bulldozers and chainsaws. Already more than 80 per cent of India's forests have been destroyed. Still more forests are being cut down in order to sell firewood and lumber, plus to clear the land for farming.

  7. OCEAN, SEA AND LAKE FISH… LITTLE FRIENDS…

  8. LEOPARD • Besides that, the leopards were poached illegally for their valuable skin and body parts. In the 1980s and 1990s, the demand for their skins increased sharply due the furs’ popularity in fashion.
