Ways You Can Save the Enviorment

If everyone would do some of these things everyday, we would be stopping the global warming process.

At home:
Recycle everything
newspapers, bottles and cans, aluminum foil, etc.
Don't leave water running needlessly.
Turn off the lights, TV, or other electrical appliances when you are out of a room.
Flush the toilet less often.
Turn down the heat and turn off the water heater before you leave for vacation.

In the yard:

Take extra plastic and rubber pots back to the nursery.

Put up birdfeeders, birdhouses, and birdbaths.

Use only organic fertilizers.

In the car:

Recycle your engine oil.

Keep your tires properly inflated.

Carpool, if possible.

What Scientist Say about Endangered Species

A major international study shows that global warming may drive a quarter of land animals and plants to the edge of extinction by 2050. Between a third and half of land animal and plant species will face extermination. "The news is not very encouraging", it suggests that species' extinctions following on from global change will broadly be in the same order of magnitude as species lost due to habitat destruction", said Stuart Pimm, an expert in extinctions and biodiversity at Duke University, North Carolina. Chris Thomas, from the University of Leeds, said "the effects of climate change should be considered as great a threat to biodiversity as the "Big Three" - habitat destruction, invasions by alien species and over exploitation by humans".
Both Thomas and Pimm agree that to change climate change, serious and immediate action must betaken at the highest level. This includes cutting emissions of greenhouse gases, employing new energy efficient technologies and using strategies to sequester carbon dioxide from the atmosphere.

Any Solutions? Who Wants to Help?



The World Wildlife Fund has been doing a lot to help animals who are victims to global warming. The WWF is working with governments, power companies, and individuals and communities to reduce emissions of heat-trapping gases that cause global warming. They made the Climate Savers Act which allows companies to take a part in helping the environment of animals.The seven companies the WWF are working with are IBM, Johnson & Johnson, Polaroid, Nike, Lafarge, The Collins Companies and Sagawa Express. With the help of these companies the plan is to customize progressive business plans for reducing greenhouse gas emissions, especially focusing on carbon dioxide emissions. Today the WWF is the largest independent member-based conservation organization in the world. It has 4.7 million supporters, and projects in almost 100 countries. WWF invites many companies to come and join them in fighting global warming. WWF also has staff working around the world on climate programs and research projects.

Climate Change Affect on Wildlife

Most species that live int he water such as amphibians will be hit the hardest, thus resulting in the global mean temperature of the earth rising changes in salinity, water temperature, increases in sun exposure in areas due to evaporation, melting ice, and other problems. For example: the Golden Toad use to be found in the Monteverde in Costa Rica. This animal is thought o be extinct due to the the high temperature which results in drought. The Golden Toad was also in wet climates but the growing period of drought made it immune to diseases and infections.
This toad may have been the one of the first victims of global warming. Another example is trout and salmon. These fish live in cold water, but due to global warming ( the rise of temperatures) they are losing a very important habitat. Many animals eat trout and salmon, but what would happen if they were to become non-existent? There will prove to be an even BIGGER problem because these animals will either die or eat other animal which will mess up the food chain.

Impacts on WIldlife

All organisms depend on habitats for food, water and shelter. Climate changes can effect this. It can alter behavior population sizes, species distributions, plant and animal communities, and ecosystem functions and stability. Species that have a small population are most at risk because they are not able to move to different habitats.
Egg laying, flowering, and spawning are occurring earlier in many species and in some cases it disrupts the delicate cycles that ensure that insects and other food are available for young animals.
Global warming increases droughts and is already causing extictions in vulnerable species. About 70 species of harlequin frogs in Central and South America have been driven to extinction by a disease that is linked with global warming. This is due to warmer temperatures that can cause increased cloud cover that creates conditions for a fungus that kills the frogs. Can you see how global warming can affect the ecosystem?

Adapting to Rapid Climate Change

Some species of animals are changing their behavioral patterns in order to adapt to the rapid climate change, scientist believe. Examples are Canadian red squirrels. They are staring to reproduce earlier int he year, German blackcap birds are migrating and are arriving earlier at their nesting grounds, and northern American mosquitoes living in water-filled leaves of carnivorous plants which can also adjust their life cycles. Professor of biology at Oregon, William Bradshaw, said that global warming is going at a faster rate at more northerly latitudes which is causing longer growing seasons. "Over the part 40 years animal species and populations have been migrating, developing or reproducing earlier", says Professor Bradshaw.
