-    use alternative power supplies (sollar, wind, ground, water)
-    better exhaust systems in the cars, less cars and gases
-    try to recover supplies like trees
-    stop killing threatened animals
Pollution
-    affects air, water, land, forest, people, animals and plants
-    air pollution: indust. prod. Smoke, dust, car exhaust, factories and power stations
-    mixed with water vapour: acid rains – kill trees and plants
Trees
-    lungs of our planet
-    carbon dioxide – oxygen
-    rain forests are being destroyed 50% production of oxygen
Greenhouse effects
-    cause climate change, without – no life here, it warms the earth, traps solar radiation
-    prevent heat from escaping
-    manmade atmospheric emissions: rise in Earth’s temperature
-    melting of arctic ice (icebergs), flooding large areas
Ozone
-    it forms a layer in upper atmosphere - protect life from ultraviolet rays
-    cause skin cancer
-    it is damaged by manmade gases (Freon, or methane)
-    ozone hole
