Although the problem hasn't received much publicity in recent years, we are still far from answering the question of how we will continue to supply enough energy to satisfy the world's steadily increasing appetite for it. Though new discoveries made and exploited at the cost of environmental damage have delayed the crisis, sooner or later a crisis will happen. When it does, it will threaten our economic prosperity and our way of life.
However, there is hope; therer are solutions. One of these is tidal power. It may be as close as we can get to a totally renewable and completely clean energy source. Tidal power generators utilize the rise and fall of the ocean waters to spin turbines and produce electricity. No pollution is produced by such a system, and since it is driven by gravity, it is for all practical purposes inexhaustible. Unfortunately, there aren't many places wherer the tides rise and fall enough to make such a system practical, but combined with other new energy sources, tidal power could help us avoid a crisis that would change the world for the worse.

Our modern world faces serious environmental problems. Global
warming is causing the polar ice caps to melt. The earth is running out
of energy. Sadly, we continue to waste what's left on the planet, thinking
little of the future.
Former US Vice President Al Gore brings these issues into sharp
focus. His Oscar-winning film An Inconvenient Truth warns of deadly
tsunamis, floods, droughts, and heat wave. If humans don't make
lifestyle changes, in 10 years the damage they have done to the planet
will be beyond repair!
To make real changes, everyone needs to do their part. Recycling
used goods and buying reusable products are ways to help the
environment. In response th this call, some companies introduces
new Cycle Energy Blue rechargeable batteries. These batteries are those
people's effort to give a safer, cleaner planet to the next generation.
I hope it will be good for your schoolwork of summer vacation!

Going Green in Thailand Eco-Awareness in Ko Samui
Travel and tourism is the world's largest industry and touches every part of a country's economy.
In 1999, travel and tourism, around the world generated 192 million jobs and $3 trillion of GDP. According to forecasts by the World Travel & Tourism Council, it will continue to grow by three percent per annum until 2010.
In some countries, such as Thailand, there will be faster growth rates, and whilst this is good news in terms of increased wealth and greater employment for the country, it foretells of danger ahead. Indeed, growth in travel and tourism, developed in an unsustainable manner, may seriously affect the economies of countries around the world.
This is not a new revelation, nor is it a recent phenomenon, but it is important.
In 1992, at the Earth Summit in Rio, 182 countries agreed to work together to save the planet. From this Summit, the World Tourism Organization, the World Travel & Tourism Council, and the Earth Council devised a set of safeguards - a blueprint - to apply to the travel and tourism industry. These organizations foresaw a need to act immediately for the sake of future generations.
A document, entitled "Agenda 21 for the Travel & Tourism Industry," (www.wttc.org) describes the actions required by the industry. These actions may appear daunting, but the consequences of inaction could be serious with economic penalties on businesses and potentially irreversible damage to the landscapes, wildlife, historic monuments, and cultural diversity on which the industry depends for its very survival. This could be the short-term effect.
