• Population growth • Acid rain • Acidification of lakes • Deforestation • Bioaccumulation • Ozone depletion • Carbon-Flouro-Carbons • Pollution • Exxon Valdez oil spill • Global Warming
• Industrialization • Burning fossil fuels • Non-renewable resources • Pollution • Increased CO2 levels
• Burning of fossil fuels releases sulphates and nitrates into air • Sulphates and nitrates mix with water vapor in air and form sulphuric acid and nitric acid
• Lakes and ponds can become so acidified that no life can live in them!
• Population growth leads to the loss of natural habitats • Cut down trees to build new homes • Loss of biodiversity • Loss of oxygen producers and CO2 eliminators
• Water Pollution • Oil Spills • Gasoline spills • Gets into drinking water
• Increase in CO2 • Increase in greenhouse effect • Increase in global temperatures
• Simply means the diversity, or variety, of plants and animals and other living things in a particular area or region. • It is important because everything that lives in an ecosystem is part of the web of life, including humans. Each species of vegetation and each creature has a place on the earth and plays a vital role in the circle of life. Plant, animal, and insect species interact and depend upon one another for what each offers, such as food, shelter, oxygen, and soil enrichment.
• Climate change, brought about by emissions of greenhouse gases when fossil fuels are burnt, is making life uncomfortably hot for some species and uncomfortably cold for others. • Pollution is currently poisoning all forms of life, both on land and in the water, and contributing to climate change. • Habitat loss and destruction, usually as a direct result of human activity and population growth, is a major force in the loss of species, populations, and ecosystems.
• The protection, preservation, management, or restoration of wildlife and of natural resources such as forests, soil, and water.
• Do not waste paper, use only as much as you require. Do not scribble on it or tearing it off after writing just a line or two. • Use recycle paper as far as possible. • Try to reuse the envelopes where ever possible. • 75% of all fisheries are fully exploited or over-fished. Species like cod, haddock and halibut are already threatened. If we do not move towards sustainable use, there will be no fish left for our grandchildren. • Climate change is considered to be the greatest challenge for humanity. With changing conditions, ecosystems and habitats will change as well. It is an obligation to fight climate change and make sure that species can migrate or adapt to new surroundings.
